This worksheet is designed to teach
one-to-one correspondence, a foundational math concept where each item in one group is matched with exactly one item in another group. The goal is to determine which group of items (ice creams, carrots, hats, or cheese) matches the number of animals or children shown.
Let’s go through each section step by step:
---
1. Ice Creams for Children
-
Number of children: 4
-
Groups of ice creams:
- Group A: 5 ice creams
- Group B: 4 ice creams
- Group C: 3 ice creams
✔ Correct answer: Group B
Why? There are 4 children, so they need 4 ice creams — one for each child. Group B has exactly 4 ice creams, matching the number of children.
---
2. Carrots for Rabbits
-
Number of rabbits: 5
-
Groups of carrots:
- Group A: 5 carrots
- Group B: 6 carrots
- Group C: 4 carrots
✔ Correct answer: Group A
Why? There are 5 rabbits, so they need 5 carrots — one per rabbit. Group A has exactly 5 carrots, so it matches.
---
3. Hats for Children
-
Number of children: 6
-
Groups of hats:
- Group A: 8 hats
- Group B: 6 hats
- Group C: 7 hats
✔ Correct answer: Group B
Why? There are 6 children, so they need 6 hats — one for each child. Group B has exactly 6 hats, making it the correct match.
---
4. Cheese for Mice
-
Number of mice: 7
-
Groups of cheese:
- Group A: 6 pieces of cheese
- Group B: 7 pieces of cheese
- Group C: 8 pieces of cheese
✔ Correct answer: Group B
Why? There are 7 mice, so they need 7 pieces of cheese — one for each mouse. Group B has exactly 7 pieces, so it matches perfectly.
---
✔ Summary of Answers:
| Section | Correct Group | Reason |
|--------|----------------|--------|
| Ice Creams | B | 4 ice creams = 4 children |
| Carrots | A | 5 carrots = 5 rabbits |
| Hats | B | 6 hats = 6 children |
| Cheese | B | 7 pieces = 7 mice |
This worksheet helps students understand that
each person/animal gets one item, and the total number must match exactly — this is the essence of
one-to-one correspondence.
Parent Tip: Review the logic above to help your child master the concept of 1 to 1 correspondence worksheet.
