   Step 1: Hana walks from one end of the sandbox to the other, placing one foot directly in front of the other. Step 2: She counts each footstep she takes. Step 3: She counted 12 footsteps from one end to the other. Step 4: The number of footsteps equals the length of the sandbox in footsteps. Therefore, the sandbox is 12 footsteps long.

3. The bookshelf is 35 blocks long. How many blocks long is it? Answer: 35 Solution: Read the problem carefully: 'The bookshelf is 35 blocks long.' This means when we measured the bookshelf using blocks placed end to end, it took 35 blocks to match the bookshelf's length.
   Full step-by-step solution

   Step 1: Read the problem carefully: 'The bookshelf is 35 blocks long.' Step 2: This means when we measured the bookshelf using blocks placed end to end, it took 35 blocks to match the bookshelf's length. Step 3: Therefore, the bookshelf is 35 blocks long. The answer is 35.

4. Tommy is measuring his toy car using building blocks. He lines up the blocks end to end next to the car. The car is as long as 7 blocks placed in a row. How many blocks long is the toy car? Answer: 7 Solution: The problem states that the toy car is as long as 7 blocks placed end to end. When measuring with non-standard units, the number of units that fit along the object equals its length in those units.
   Full step-by-step solution

   Step 1: The problem states that the toy car is as long as 7 blocks placed end to end. Step 2: When measuring with non-standard units, the number of units that fit along the object equals its length in those units. Step 3: Since 7 blocks match the length of the car, the car is 7 blocks long. The answer is 7.

5. Sarah is measuring her pencil using paper clips. The pencil is as long as 6 paper clips placed end to end. How many paper clips long is the pencil? Answer: 6 Solution: Sarah is measuring her pencil using paper clips. The problem says the pencil is as long as 6 paper clips placed end to end. Interpret the measurement.
   Full step-by-step solution

   Step 1: Understand the problem. Sarah is measuring her pencil using paper clips. The problem says the pencil is as long as 6 paper clips placed end to end. Step 2: Interpret the measurement. If 6 paper clips placed end to end equal the pencil's length, then the pencil's length in terms of paper clips is exactly 6. Step 3: State the answer. Therefore, the pencil is 6 paper clips long. Final Answer: 6

6. Aroha is measuring her kitchen table using hand spans. She places her hand flat on the table, thumb to pinky, and moves it along from one end to the other. She counts 11 hand spans.

9. Tommy has a pencil that is 8 paper clips long. His friend Sarah has a pencil that is 5 paper clips long. How many paper clips long are their pencils if you put them end to end? Answer: 13 Solution: Tommy's pencil is 8 paper clips long. Sarah's pencil is 5 paper clips long. We are putting them end to end, so we need to find the total length in paper clips.
   Full step-by-step solution

   Step 1: Understand the problem. Tommy's pencil is 8 paper clips long. Sarah's pencil is 5 paper clips long. We are putting them end to end, so we need to find the total length in paper clips.
