Let’s break down three key teaching points from this resource and how to implement them in your classroom.

1️⃣ Teaching Point #1: Mastering Decimal Addition & Subtraction

How to Implement

  1. Quick Review: You can start with a 5-minute refresher on how to align decimals and borrowing/carrying when needed. Basically the stuff kids already know
  2. Think Aloud: Teach kids 1–2 problems on the board, and say out loud your thought process.
  3. Turn & Talk: Have your students explain the problem’s steps to a partner before they even start.
  4. Independent Work: Give out the Color by Number worksheet and let students solve it.
  5. Check & Reflect: Let students compare their answers with a partner before coloring.

Practice Exercise

Here are a few warm-up problem set you can use with your kids:

  • 3.42 + 2.58 = ?
  • 7.1 – 3.89 = ? A good one to discuss how to align decimals with 1 and 2 decimal places
  • 9.03 + 5.77 = ?

Discuss the most common mistakes (misaligned decimals, forgetting to borrow, etc.).


2️⃣ Teaching Point #2: Building Confidence with Self-Checking

How to Implement

  1. Encourage Estimation: Before solving, have students round numbers and estimate to check their reasonableness.
  2. Check in Pairs: After every five problems, students compare answers before coloring.
  3. Spot the Error: If students see an unexpected color pattern, guide them to rework the problem.

Practice Exercise

Have students estimate first and then solve:

  • 4.92 + 3.17 (Estimate: 5 + 3)
  • 10.5 – 7.63 (Estimate: 10 – 8)
  • 6.89 + 1.56 (Estimate: 7 + 2)

This step reinforces number sense and problem-checking habits.


3️⃣ Teaching Point #3: Increasing Engagement with Color & Creativity

How to Implement

  1. Make It a Challenge: Time students and see who correctly solves and colors first.
  2. Personalized Touch: Allow students to choose their own coloring shades.
  3. Create a Math Wall: Display finished work to reinforce effort and accuracy.
  4. Incorporate Tech: Have students take a photo of their work and explain their thinking via a digital tool like Flipgrid.
