I’m excited to share how MathReps can transform daily math practice into a fun and engaging activity for your students. Whether you’re a seasoned teacher or just starting your journey, MathReps are a fantastic tool to build fluency and confidence in math concepts.
For today’s demonstration, let’s dive into a 2nd-grade MathRep and explore how you can use it in your classroom. This template can also be found on Wipebook Workbooks and Kami!
Step-by-Step Guide: Using MathReps in Your Classroom
1. Set Up the Numbers
For this example, we’re working with 237 and 422. Begin by deciding whether your students will add or subtract these numbers. For this demonstration, we’ll focus on addition.
2. Use a Pictorial Model
Start by setting up the numbers in a pictorial model.
- Creating a 100’s chart will help students represent each digit in the numbers.
- Each x will represent the ones (I prefer x’s over dots as it can become hard to distinguish individual dots)
- Each l will represent the tens
- Each square will represent the hundreds
- Count the ones, tens, and hundreds in each number:
- Ones: 7 ones + 2 ones = 9 ones
- Tens: 30 tens + 20 tens = 50 tens
- Hundreds: 200 hundreds + 400 hundreds = 600 hundreds
Add these values together:
659
3. Transition to the Base 10 Model
Once students understand the pictorial model, encourage them to transfer the information to a base 10 model by breaking down the numbers into expanded form:
- 237 → 200 + 30 + 7
- 422 → 400 + 20 + 2
Have the students add the expanded forms:
- Add the ones: 7 + 2 = 9
- Add the tens: 30 + 20 = 50
- Add the hundreds: 200 + 400 = 600
Bring it all together:
600 + 50 + 9 = 659
Why It Works
This activity bridges the gap between pictorial models and abstract math concepts. Students not only practice addition but also develop a deeper understanding of place value and number decomposition.
