Show 43 using tens and ones. Use a drawing or base-ten blocks.
What is 4 tens and 3 ones?
Break 23 into tens and ones. Draw a model.
What is 2 tens and 3 ones?
What is ten more than 26? Show with a drawing or base-ten models.
What is 36? 3 tens and 6 ones.
Find the sum: 34 + 5. Show with a drawing or base-ten blocks.
What is 39?
Show 47 using tens and ones in two different ways.
1. What is 4 tens and 7 ones?
2. What is 40+7?
3. What is 3 tens and 17 ones?
Show two different ways to make 56 using tens and ones. Draw or use models.
1. What is 5 tens and 6 ones?
2. What is 50 + 6?
3. What is 4 tens and 16 ones?
What is 10 more than 95? Show using a drawing or base-ten model.
What is 105? 10 tens and 5 ones.
Find the sum: 46 + 10. Use a drawing or base‑ten model and write the equation. Explain why adding a multiple of 10 is easy.
What is 56? Adding a multiple of 10 is easy because the tens places increases by 1.
I have 2 tens and 9 ones. What number is that? Show with a drawing and write the number.
What is 29?
Pick a number between 30 and 70. Show three different ways to make that number using tens and ones. Draw or model each.
Ex: What is 34? 3 tens and 4 ones. 30 + 4. 20 + 14.
For the number 83, show and explain ten more and ten less using drawings or models.
What is 93, 9 tens and 3 ones? What is 73, 7 tens and 3 ones?
Solve 29 + 8. Show your work with drawings or models, write the equation, and explain if you used regrouping (making a ten).
What is 37? I regrouped 9+8 by replacing 10 ones with a ten and having 7 ones left over.
