The Only Multi-digit Addition and Subtraction Practice I’ll Use This Year

BySadia

Raise your hand if you’ve ever printed a math worksheet, handed it out and watched your entire class immediately ZONE OUT.

Same. Dry, black and white worksheets suck the energy right out of math time for your students and for you.

They’re boring. They don’t work. And worst of all? They make these core basic operations reviews feel like a chore.

But here’s the thing, addition and subtraction practice doesn’t have to be dull.

When you mix in color by number printables or activities with riddles to review, your kids are engaged, your classroom is calm, and your math centers become something everyone actually looks forward to.

I’m breaking down the multi-digit addition and subtraction practice worksheets I’ll use this year, because they work and they save my sanity.

Strategy 1: Use Multi-digit Addition and Subtraction Escape Room to Make Practice Fun

What would life be like if you didn’t have to convince kids that the more they practice, the better it is for them?

What better way to practice than to disguise it as a riddle and increase their curiosity along with math skills? These are just a few of the reasons why math riddles are magic, I use during review time.

The only 2 and 3 digit Addition and Subtraction Practice Activity Needed in your elementary math class | Multidigit Addition and Subtraction Escape Room printable worksheets activity for 3rd 4th and 5th grade

My students get self motivated to solve them, and that’s not just to get the math right but to solve the riddle. That little “aha” moment at the end makes the work feel like a game to them, not a worksheet.

The best part? Riddle worksheets are also self-checking. If the answer doesn’t make sense? It means it’s time to double-check their math without you having to hover or correct them. The reason why it’s a total win for me.

Escape Room-style riddles are also perfect for independent work, partner pairs, or small groups.

You’ll love the classroom management piece (hello, quiet engagement), and your students will love cracking the code.

Still not sure? Try what I use and see your kids filled with excitement: Multi-Digit Addition and Subtraction with Regrouping Escape Room.

Strategy 2: Color by Number for Fluency & Focus

You know those kids who can’t sit still for more than five minutes? Yeah, even they get into color by number math. The visuals pull them in, and the structure keeps them focused. It’s like sneaking in math fluency practice… with crayons.

To be honest color by number is a game-changer for independent work, early finishers, math centers, basically anytime you need your students to be engaged without needing your constant attention.

And unlike flashcards, these worksheets build fact fluency in a low-stress, low-prep way that students actually enjoy.

My go-to resources that I pull again and again are: Add/Subtract/Multiply/Divide Color by Number Worksheets

My students actually ask for these during math review. Yep. It’s that fun.

Strategy 3: Mix Seasonal + Skill-Based Review

Want to keep review fresh without re-inventing the wheel every week?

Seasonal printables are your best bet. You’re still hitting the same addition and subtraction skills, just dressed up for fall, Halloween, winter, or whatever season you’re in.

Students stay engaged because it feels new even though the practice is familiar. Teachers win because it’s low-prep and high-impact.

It’s perfect for early finishers, homework, and sub plans basically anytime you need a minute to breathe.

Teachers like you find these a fun addition to their toolkit: any seasonal or holiday themed addition and subtraction practice.

What would life be like if you didn’t have to reinvent the wheels?

If you want your students engaged, confident, and actually enjoying math this year, start with tools that make them smile and think. Riddles, color by number, seasonal printables, they’re more than just fun. They’re effective.

You don’t need to reinvent math review. You just need the right tools in your teacher box.

Empower Students to Learn Fractions With Word Problems Using Exciting Worksheets and Epic Activities
BySadia

Teaching adding and subtracting fractions isn’t easy, especially when you’re teaching upper elementary school kids.

You not only have to explain the basics but also make sure your fractions lessons are engaging enough so they pay full attention during the learning period and do not get distracted.

In this blog post, I will discuss with you some new and easy ways I have found helpful in teaching fraction operations to my kids during math class to help them engage with the problems at hand and be happily willing to practice adding and subtracting fractions.

So, let’s dive in…

1. Fun Fractions Maze Activity with Task Cards – Save the Queen

This activity includes a printable self-checking maze that you can use with your kids to have them practice addition, subtraction, multiplication, or division of fractions with unlike denominators.

Each fraction operations maze activity comes with 12 task cards and a self-checking FUN maze, which keeps kids inspired to learn, but you do not have to spend all day grading.

The activity is story-based, in which your kids become detectives, helping the Queen bee, who is lost in the jungle, return home. For that, your kids have to work through the problems to bring her back home.

Once the kids have completed the activity, you can use the printable reward card to reward your kid’s hard work and create a positive motivation for them to practice their math skills happily the next time!

2. Solve the Room Fractions Activities

Are your kids bored with their daily boring math routine work and want to have some fun and excitement while learning new concepts?

Try adding Solve the Room activities to help them get moving and learn all at the same time!

Solve the Room is my kid’s favorite activity as it allows them not to be glued to their desks but to move around the room while working on the problems. The best part is that it is very easy to set up.

All you have to do is print the question cards and place them in different spots inside your classroom. Next, give students their recording sheets. Kids move around the room, looking for problems with adding and subtracting fractions.

They solve the problems and record their answers on the recording sheets provided. You can also instruct them to use the back of the recording sheet to show their work, which is always a good idea.

3. Color by Number Fractions Activities

Coloring is LOVE for all my kids – no matter their age.

Primary, lower elementary, or upper elementary, you name it!

The easiest way teachers can use it to their advantage is by making any doodle on a piece of paper along with a bunch of practice problems and giving them to solve and color.

Using color by number activities in elementary math classes can enhance engagement, reinforce concepts like perimeter and area of complex figures and volume of rectangular prism creatively, and facilitate differentiation for diverse learning levels.

These activities make working on math problems more enjoyable for students and provide valuable tools for teachers to effectively deal with the challenges of teaching elementary mathematics.

Looking to add some fun color by number activities to your next lesson? I have created these 5th grade fraction operations color by number activities that you can use to skyrocket your class math learning outcome. Want some fraction word problem worksheets? Click HERE to check them out.

BySadia

Are you ready to learn how to make Boring Worksheets Fun in your next math class and make math the coolest part of your kids day . Try out these fun ideas and say goodbye to boring old traditional worksheets.

In this post I’ve got 11 super fun ideas to make math feel like a game. Imagine your students racing to finish math problems, playing bingo with math questions, or even turning your classroom into a mini escape room.

Let’s make sure learning math is not just about numbers but also about having a great time. And yes you can have fun in you math class even using your old math worksheets that maybe your district in mandating you to use.

1. Math Races:

I am all about healthy competition and honestly my kids even love it. All you have to do is give your students a competitive atmosphere by timing them as they complete their assigned math activities or worksheets. This will motivate them to finish quickly and accurately and turn the routine task into an exciting race against the clock.

2. Worksheet Bingo:

Another idea that you can implement is turn your normal daily worksheet problems into a bingo game. Which basically means with each correct answer you made your students to mark off a task or problem completed and check off a square. What can even motivate them more is to give them a small prize or award recognition for their effort or to the one that get a line first.

3. Math Puzzles:

Using puzzles as worksheets where with every problem that they solve gives them some clue for the next problem they need to solve. It can be a riddle, a hidden message, or a mystery that gets solved with each correct answer. I used on of these mystery puzzles worksheets for reviewing addition and subtraction inside my classroom and my kids just loved it.

4. Interactive Worksheets:

Using technology to turn your already made worksheets into interactive digital activities. This way you do not have o do the work again and still keep your kids engaged in fun way. Best way I do it is by turning the task cards in to images and then adding those task cards as background images inside Google Slides(TM) and add a text box on top of it for my kids to put their answers.

Second thing that you can do is insert the same task cards as images in Google forms(TM) and use the multiple choice option to create a multiple choice self Checking activity like this for your class, either way your kids are gonna love the special twist of learning experience you put on turning boring worksheet fun.

5. Group Challenges:

Team work in important for every classroom whether its ELA, math, arts or even music. No matter what you are teaching encouraging teamwork by having students work in small groups to complete the the assigned math task. This way they can develop their social and leadership skill along side learning which is a win win. Students can discuss strategies and help each other out which fosters a collaborative learning necessary for their future growth.

Creating activities like math mazes, puzzles or mystery activities gives them the opportunity they need to develop their collaborative skills and turn boring worksheets into fun learning experiences.

6. Real-World Application:

Connect math problems to real-life scenarios. This not only makes the worksheet more interesting but also helps students understand the practical application of what they’re learning.

7. Math Stations:

Set up different stations around the room, each with a math task or worksheet to complete. Students rotate through the stations that breaks the monotony of boring routine and adds movement and excitement to the class.

8. Creative Rewards:

Positive reinforcement is essential for kids to learn and get motivated to do better next time. You can give them their favorite snack as an award, a Home work pass or a chance to play their favorite game.

9. Incorporate Art:

Have them illustrate their mathematical thinking into art. This gives them the ability to develop further their problem solving skills and critical thinking skills.

10. Math Journals:

Math journals like goal journals and others can be useful. Instead of boring worksheets, have students keep math journals where they not only solve math problems but also write about their thought process, making the activity more reflective and personalized. This helps students organize their thought and develop creative thinking.

11. Escape Rooms:

Design worksheets that mimic an escape room challenge. Each correct answer helps “unlock” the next section until they “escape” by completing the entire sheet. This adds an element of adventure to the task.

Remember, the goal is to make learning math not just educational but incredibly fun too. So, try to use these strategies and ideas to your advantage, and turn boring worksheets fun and use them to your advantage. Here is one such example of an multi digit addition and subtraction escape room I did in my that my kids totally loved.

Use this and see your students discover the joy in numbers, and most importantly, develop a lasting love for learning. Implementing all these ideas might require a bit more effort on your part but I assure you it will be 100% worth it.

How to Teach GCF and LCM With NO Stress This Halloween
BySadia
Halloween week in the classroom is chaos. Between sugar highs, costume distractions, and a packed schedule, the last thing you need is a complicated GCF and LCM practice lesson.

But October is also a great time to hit those tough concepts like Greatest Common Factor (GCF) and Least Common Multiple (LCM) practice especially, if you’ve got the right tools.

That’s why I created these three hands-on, no-prep Halloween-themed math activities that actually get your students excited about GCF and LCM.

These aren’t just worksheets, they’re interactive, self-checking, and fun.

In this post, I’m breaking down how each activity works and how you can use them in your classroom this October.

GCF and LCM Practice Halloween Coloring

Kids in my class LOVE coloring period. The truth is, we need to use more coloring math practice in the age of AI than ever before.

The reason is that kids these days aren’t as calm as they used to be. Coloring helps them calm down due to their hyperactive abilities.

This Halloween color-by-number activity blends math + art to keep kids engaged while practicing core skills.

Students solve GCF and LCM problems, find the matching color, and use it to complete a spooky themed image that you can display on bulletin board.

Why it works:
- Self-checking format helps students correct their own work
- Visual + hands-on = more focused engagement
- Works great for early finishers, math centers, or calming down a hyped-up classroom
The best part? It’s Print and go! No prep needed.

It’s perfect for days when you want meaningful review without managing chaos.
