How Well Can You Measure? - Free Printable

To solve this problem, we need to figure out which combination of the available measuring cups (1 c., ½ c., c., and ¼ c.) adds up to each amount listed.

Important Rule from the instructions: You do not have a c. cup or a ¾ c. cup. You must build those amounts using the cups you *do* have.

Here is the step-by-step logic for each row:

1) 1 c.
- You have a 1 c. cup.
- Use: 1 c.

2) ¾ c.
- We don't have a ¾ cup. We need to make it.
- Think: ½ + ¼ = 2/4 + 1/4 = 3/4.
- Use: ½ c. and ¼ c.

3) ½ c.
- You have a ½ c. cup.
- Use: ½ c.

4) ⅔ c.
- We don't have a ⅔ cup. We need to make it.
- Think: ⅓ + ⅓ = 2/3.
- Use: two ⅓ c. cups (Check the ⅓ c. column twice, or just understand that you fill the 1/3 cup two times). *Note: In these tables, usually you check the box for the cup you use. If you use the same cup multiple times, you might mark it once but imply repetition, or mark it twice if allowed. However, standard practice for these worksheets is often to find the unique cups needed. Let's look closer. Actually, usually, you just list the components. So for 2/3, you use the 1/3 cup twice. Since there is only one column for "1/3 c.", we will assume checking that box implies using that tool. But wait, looking at row 9 (1 2/3), it's clearer. Let's stick to marking the cups involved.*
- Correction: The prompt says "Put a check mark under the measuring cup you would use". It doesn't explicitly say you can't use a cup more than once. For 2/3 c., you strictly need the 1/3 c. cup (used twice). You cannot make 2/3 with 1/2 and 1/4 easily (1/2+1/4=3/4, too big. 1/2+1/3=5/6, too big). So the only way is 1/3 c. (twice).

5) ⅓ c.
- You have a ⅓ c. cup.
- Use: ⅓ c.

6) ¼ c.
- You have a ¼ c. cup.
- Use: ¼ c.

7) 1 ⅓ c.
- This is 1 whole cup plus 1/3 cup.
- Use: 1 c. and c.

8) 2 ¾ c.
- Break it down: 2 wholes + ¾.
- We know from #2 that ¾ is made of ½ and ¼.
- So we need two 1-cup measures, one ½-cup measure, and one ¼-cup measure.
- Use: 1 c. (twice), ½ c., and ¼ c.

9) 1 ⅔ c.
- Break it down: 1 whole + ⅔.
- We know from #4 that ⅔ is made of two ⅓s.
- So we need one 1-cup measure and the 1/3-cup measure (used twice).
- Use: 1 c. and ⅓ c. (twice).

10) 2 ½ c.
- Break it down: 2 wholes + ½.
- Use: 1 c. (twice) and ½ c.

Final Answer

Here are the checkmarks for each row. An X indicates you should put a checkmark in that box.

| Amount | 1 c. | ½ c. | ⅓ c. | ¼ c. | Notes |
| :--- | :---: | :---: | :---: | :---: | :--- |
| 1) 1 c. | X | | | | Use the 1 cup once. |
| 2) ¾ c. | | X | | X | ½ + ¼ = ¾ |
| 3) ½ c. | | X | | | Use the ½ cup once. |
| 4) ⅔ c. | | | X | | Use the ⅓ cup twice. |
| 5) c. | | | X | | Use the ⅓ cup once. |
| 6) ¼ c. | | | | X | Use the ¼ cup once. |
| 7) 1 c. | X | | X | | Use 1 cup once, ⅓ cup once. |
| 8) 2 ¾ c. | X | X | | X | Use 1 cup twice, ½ cup once, ¼ cup once. |
| 9) 1 ⅔ c. | X | | X | | Use 1 cup once, ⅓ cup twice. |
| 10) 2 ½ c. | X | X | | | Use 1 cup twice, ½ cup once. |
