Chapter 3.6
Using models to add up to 20
What You'll Learn
Use block models to visualize addition problems up to 20
Identify tens and ones values in sums using base-ten models
Recognize how blocks represent quantities in place value format
Break down addition into tens and ones for easier computation
What You'll Practice
1
Adding numbers up to 20 using visual block representations
2
Identifying tens and ones in block model sums
3
Using base-ten blocks to solve addition problems
Why This Matters
Block models help you visualize how numbers work in our base-ten system, making addition easier to understand. This foundational skill builds your number sense and prepares you for mental math, regrouping, and larger addition problems throughout elementary math.
