Let’s solve this worksheet step by step. The goal is to count objects and express the total as “___ tens + ___ ones = ___”.
---
##
Part A: Count the number of objects in each set, and write how many in all.
1) Pizza and strawberries
-
Pizza: Has 10 slices → that’s
1 ten
-
Strawberries: There are 6 individual strawberries → that’s
6 ones
- So:
1 ten + 6 ones = 16
✔ Answer:
1 ten + 6 ones = 16
---
2) Flowers in a vase and loose flowers
-
Vase: Contains 10 flowers →
1 ten
-
Loose flowers: 4 flowers outside →
4 ones
- So:
1 ten + 4 ones = 14
✔ Answer:
1 ten + 4 ones = 14
---
3) Books on shelf and loose books
-
Shelf: 10 books (2 rows of 5) →
1 ten
-
Loose books: 5 books beside shelf →
5 ones
- So:
1 ten + 5 ones = 15
✔ Answer:
1 ten + 5 ones = 15
---
##
Part B: Circle a group of ten in each set. Write how many in all, how many tens and ones.
1) Blue hexagons
- Total hexagons: Let’s count — there are 13.
- Circle any 10 of them (e.g., first two rows: 5 + 5 = 10).
- Remaining: 3 hexagons → 3 ones.
- So:
13 = 1 ten + 3 ones
✔ Answer:
13 = 1 ten + 3 ones
---
2) Blue water droplets
- Total droplets: Count them — 17.
- Circle 10 (e.g., first two rows: 5 + 5 = 10).
- Remaining: 7 droplets → 7 ones.
- So:
17 = 1 ten + 7 ones
✔ Answer:
17 = 1 ten + 7 ones
---
3) Orange dots
- Total dots: Count — 19.
- Circle 10 (e.g., first row: 10 dots).
- Remaining: 9 dots → 9 ones.
- So:
19 = 1 ten + 9 ones
✔ Answer:
19 = 1 ten + 9 ones
---
##
✔ Final Answers:
A)
1) 1 ten + 6 ones =
16
2) 1 ten + 4 ones =
14
3) 1 ten + 5 ones =
15
B)
1)
13 = 1 ten + 3 ones
2)
17 = 1 ten + 7 ones
3)
19 = 1 ten + 9 ones

Explanation Summary:
This worksheet teaches place value — breaking numbers into tens and ones. A “ten” means a group of 10 objects. Anything left over is “ones”. This helps build understanding of numbers 11–19 as “1 ten and some ones”, which is foundational for addition and subtraction later.
Let me know if you’d like to visualize the circling part or need more practice!
