Kids in upper elementary classrooms are more inclined to learn math through games because math games provide the same environment as today’s gadgets and screens but with the goal of learning something new.
This is why, in today’s teaching, it is more important than ever to use game-based learning methods in our math classrooms.
In my 10+ years of teaching math to elementary students, I have never encountered a time in my classes when, whenever I pull up a game, my kids do not get excited.
It has always been the case for me, no matter what the type of game is! It can be digital as well as printable but what would never happen with board games or game shows is a dry class with no learning excitement for a hard subject like math.
Honestly, I feel that having printable games or digital game-based activities should be in every teacher’s toolkit. They are a compelling way for kids to connect and engage with your teaching content. Still not convinced?
Here’s a list of why math games are important and how to integrate them into your lesson planning.
1. Enhanced Engagement during Math Class
This is what we all want? I mean, I do! And the best way to increase your class engagement is by using math games to make learning more interactive and exciting.
Gamification helps develop critical thinking skills, which are essential for children’s future success. Students are more likely to participate and stay focused when they play a game in pairs, compared to just working through a set of problems on a worksheet.
So, make your kids work in pairs next time you want them to add some accountability to your math lessons. The added accountability helps them push each other and encourages a sense of responsibility.

2. Improved Understanding with Math Games
Understanding is the most important part of the learning process. It is the integral part that should be focused on during lesson planning.
If your kids can understand the basics of any concept, like fraction operations or the order of operations, they will be able to think through them, understand them, and solve problems on their own, which should always be the goal.
This collaborative environment that is created as a result of their teamwork can help them feel more comfortable sharing their thought processes and strategies with their class fellows.
With games, we can present kids with the same math problems in various formats like multiple choice, true-false, or even open-ended, which then helps students to see concepts from different angles.
This is crucial as it deepens their understanding and helps them apply math skills in various real world situations.
During my lessons I try to give kids as many practice problems as possible, but after we have
ended a lesson I prefer other formats like multiple choice or true false using interactive activities or riddles to check their understanding and see where the gaps are!
3. Immediate Feedback
Of course, getting feedback is important! But what’s more important is making it fun not just for kids but for you too. I try to incorporate self checking games during lessons because of the immediate feedbackkk!
We all want our kids to rise and shine but none of us want to go through the painful time taking act of grading and checking the assessments and creating the report cards.
That’s why math games can actually be a handy tool. It provides us with a way to keep ourselves on top of all the stuff other than teaching by utilizing the power of active learning, allowing students to practice and reinforce their skills in an interactive way.
It allows students to quickly see the results of their actions and understand what they need to improve. This immediate reinforcement can increase their confidence and motivate them to learn more.
4. Fun and Motivation
Let’s be honest: It is a chore to make math enjoyable and personalize activities for every kid. However, I believe learning is not only enjoyable with games; students are more than ready to engage with the material. Math games can turn a challenging subject into a fun and rewarding experience, which enhances a positive attitude towards math.
Digital games can be easily integrated into your lesson plans and are great for individual or small group work. One way is to customize games for different skill levels, making sure that all students, regardless of their abilities, are challenged appropriately and can progress at their own pace.
You can create different stations with various math games, like “Digital Fraction and Decimals Pixel Art Bundle.” Just assign students one of the activities and keep them engaged by exposing them to different types of problems.
Another way is to organize math game tournaments or challenges inside the classroom to add an element of friendly competition. However, this can even create a challenge of managing competitiveness among students. For this, make sure to emphasize the importance of teamwork and collaboration more. This can motivate students to practice more and improve their math skills.
Lastly, have students discuss what they learned and reflect on their strategies after playing. This will help solidify their understanding and encourage them to think critically about problem-solving techniques.
Math games are a fun and effective way to review important math concepts like decimal operations inside classrooms. Incorporating math games into your classroom can transform the way your students learn and engage with math.

As a math teacher with various grade levels teaching experience, I know the struggle math teachers face in their day to day life. Your days are undoubtedly filled with various responsibilities, from strategizing your lessons and managing your classroom to caring for your families. Finding the time and energy to create engaging and effective teaching environments and lessons can be challenging!
This is why I have created this blog post to help teachers like you with the tools and resources you need in order to ensure your students master math while you have more time for yourself and your loved ones.
Why should you help your students in learning maths?
As teachers, I know your first priority is to help your kids master the subject with ease. This is the mere reason why I am excited to share all my valuable findings with you. All math teaching strategies to help you make an impact on students learning and foster independent problem solving and critical thinking in your students.
By implementing these strategies effectively, you can inspire a love for math and develop confidence in their abilities, which is what we all strive for as educators.
How should you think about these math learning abilities in kids:
Learning to solve math is very important for our kids’ everyday lives and a country’s growth. All those students that are good at math perform better in STEM fields which are very important in this information and technology driven digital era.
This is why it is important for schools to help kids develop their mathematical abilities. In recent studies, experts have found that one of the reasons our young learners do not perform well in maths is because math teachers simply don’t have enough knowledge of their subject.
This could be a direct result of the old-fashioned teaching methods still used in schools.
One way to fix this problem is by developing your student’s metacognitive skills. This helps them better equip themselves to solve their own problems not only in maths but in life.
How to implement this in your teaching practices:
Helping your students develop their metacognitive skills is a tedious task. But being a class facilitator to goal during your teaching would be to help them develop their own thinking for every problem that they encounter.
Let’s say your students are working through an area and perimeter of composite figures of project. They can check their understanding of the project by calculating what’s required for the task at hand. Now for every problem that they come across during practicing they should be able to plan it out and then check if the plan works. This type of thinking helps them develop the cognitive skills required to solve complex math problems.
The more your students are able to reflect, plan, and evaluate the math problem at hand the better their understanding gets with time. This is why I like to use math projects riddles and mysteries with my students during my class.
Strategies to help your kids learn math in an interesting way: Here are some math teaching strategies to help kids learn math faster and more easily:
1. Make it Relevant:
It is a powerful strategy in math education that aims to give students some real world experience in their math learning. Through this strategy the educator aims to bridge gap between abstract concepts and real scenarios application, which deepens the students understanding.
Elementary students are in the age group where they are naturally curious about their environment, so connecting math to their everyday lives captivates their interest and sparks more motivation in them.
In traditional math teaching, students are made to memorize the concept and formulas without any practical understanding. This approach keeps them wondering about the purpose of their math learning beyond the classroom. However, by making math relevant to their environment and everyday life, teacher’s have the opportunity to show how math is an integrated part of our everyday life, from simple to complex discoveries.
Ways to implement:
One way to implement this is using math problems such as calculating discounts during shopping or measuring ingredients during cooking so students can immediately see the practical usage of their abilities.
Such hands on experience solidifies your kid’s understanding of math concepts and boosts their confidence. You can even integrate math with other subjects showing its interconnection with other disciplines.
For example in science students can use mathematical formulas to understand the laws of motion, or in arts, they explore geometrical shapes and symmetry. This type of understanding nurtures a holistic approach to their learning.
In conclusion, this strategy is an essential pillar in math education. It ignites curiosity, foster engagement, and equips learners with the skills they need to tackle real-world challenges with confidence and proficiency.
As students recognize the practical relevance of math, they are more likely to approach the subject with enthusiasm and become lifelong learners and problem-solvers.
2. Hands on learning:
This strategy involves using physical objects, manipulatives and interactive activities to teach math concepts. Students interact, measure and manipulate the objects to understand abstract ideas more concretely. For instance, using counting blocks to illustrate addition and subtraction or using shapes to teach geometry. This approach caters to different learning styles, making math more accessible and enjoyable.
3. Problem-Solving Approach:
The problem-solving approach nurtures students’ critical thinking and analytical skills. Instead of relying on rote memorization, kids are presented with real-world problems that require applying mathematical concepts to find solutions. So if we can encourage them to reason through problems and instill a deeper understanding of math, this will equip them with valuable skills beyond the classroom.
4. Games and Puzzles:
Honestly, math games and puzzles make learning math enjoyable and engaging. For my kids, these create a fun learning environment where students can practice math concepts while having fun.
Games can range from board games that reinforce basic arithmetic to online math challenges that promote strategic thinking. What is most interesting to see is the element of competition between peers. It motivates students to actively participate and reinforce their learning.
5. Personalized Learning:
This strategy focuses that students have different learning paces and needs. As teachers we must adapt to cater to individual needs, offering extra support or advanced challenges based on each student’s abilities. This approach builds a positive learning experience, boosts confidence, and helps students reach their full potential.
6. Visual Representations:
Visual representations use graphs, charts, diagrams, and drawings to illustrate math concepts. It enhances comprehension and memory retention, especially for complex topics. Visualizing information helps students make connections between abstract ideas and concrete examples.
7. Real-life Problem-solving:
Connecting math to real-life situations makes the subject more meaningful and relevant to students. By presenting math as a tool to solve practical problems, such as budgeting, measurements for a classroom project, or understanding patterns in nature, students can see its importance in their daily lives and future careers.
8. Positive Reinforcement:
Positive reinforcement involves praising and acknowledging students’ efforts and achievements. Recognizing their progress and hard work promotes a positive attitude toward math. Positive reinforcement builds confidence and motivates students to continue learning and exploring math concepts.

All right, so we’re diving into the exciting and full of fun world of… 3 digit addition. As a math teacher myself, I know what you might be thinking! I know, I know. ‘three digit addition’ and ‘exciting’ are two phrases that you probably never expected to see in the same sentence. Yet, here we are!
But for a moment, I want you to picture this: your kids, completely absorbed, their minds buzzing away as they add numbers. No more expressionless eyes, no more “Do I have to?” Instead, they’re eager. They’re engaged. They’re learning. Sounds like a far-off dream? Well, it isn’t, and thanks to the gamified math lessons, this could be the reality of your classroom.
I remember when I was a kid, and math felt like a tedious chore. But honestly, I do not want that for my kids in the classroom, so it’s time that we as math teachers, put those days behind us.
Let’s make learning two and three digit addition and subtraction worksheets a game — literally. How? Here is a step by step month-long journey to transform 3 digit addition from ‘Ugh, not again!’ to ‘Can we do more?’ in your classroom.
Week 1: Nailing the basics of the concept of 3 digit addition
Ever tried to build a castle on sand? It’s a shaky business, right? The same goes for 3 digit addition with elementary students. If you’re shaky on the basics, teachers! Well, you’re setting your class up for a castle full of confusion. Let’s clear the air on this. Shall we?
Now, for your kids to understand 3 digit addition with and without regrouping, you first need to make them recognize the importance of place values. They should’ve got hundreds, tens, and ones down. To clarify this concept to your kiddos, you can tell them to picture hundreds, tens, and ones as three shelves in a bookcase, each with a specific spot for its ‘book’.
But the thing to remember here is that it’s essential for the numbers to go in their right place. Misplace the numbers, and you’ve got chaos!
Then comes the tricky bit: carrying over. A common hiccup, often as mystifying as a magician’s trick. But it does not have to be that. You can simplify it further for them. So, if your ‘ones’ total more than 9, you ‘carry over’ the extra to the ‘tens’ shelf. Same rule for the ‘tens’ to the ‘hundreds’. It’s like when you’re packing a suitcase, and it overflows – you need another bag!
Now, what about gamification in math? Think of it like turning broccoli into a superhero. Kids love games, right? So why not use that love to turn learning 3 digit addition and subtraction with and without regrouping into a thrilling adventure?
Gamification takes the chore out of learning, and makes it interactive, and here’s the important part: it leverages our innate love for rewards. There are several platforms and tools for gamification, with different colors suited to different needs.
Week 2: Preparing the Gamified 3 Digit Addition with and without regrouping Lessons
So you’re ready to transform your class into a gaming field. But which platform to choose? It can get overwhelming pretty quickly if you do not know exactly what you are looking for. More like being in a candy shop with infinite choices.
But what I can tell you from personal experience is that features, user feedback, and, most importantly, compatibility with your class size, age group, and tech comfort is all that matter.
Selecting a platform is just the beginning. Next, you’ve got to figure out a way to add your triple digit addition and subtraction curriculum to this platform. Initially, it might feel like you are doing a puzzle. You need to break down the curriculum into daily and weekly objectives, making sure each game fits seamlessly into the learning process.
Now the most important part here is to remember, that variety is the spice of your classroom! Mixing up games and keeping the interest alive is what you should aim for. Imagine being served the same dish every day. Boring, right? The same goes for your class. So spice it up with a variety of games.
Week 3: Rolling Out the Gamified Lessons
Now comes the big reveal. Introducing the new approach to students can be a dance as delicate as a ballet. The aim? To make sure they understand how the platform works, how it’ll be integrated into their learning, and – this is key – why it’s gonna be super fun.
As the lessons roll out, be ready to wear the hat of an eagle-eyed observer. Tracking progress, and providing feedback, it’s all part of the game. It’s like being a coach on the sidelines, guiding and cheering on the players.
