Printable primary math worksheet for math grades 1 to 6 based on ... - Free Printable

To solve the problem, you need to measure the length of each item shown in the image using a ruler and round off the measurements to the nearest centimeter. Here's how you can approach this:

Steps:

1. Identify the items: The worksheet shows six items:
- A crayon
- A hot dog
- A saw
- A book
- A paperclip
- A pen

2. Use a ruler: Place the ruler next to each item and measure its length. Ensure that the zero mark of the ruler aligns with one end of the item.

3. Round to the nearest centimeter: After measuring, round the measurement to the nearest whole number (centimeter).

4. Write the answers: Record the rounded measurements in the boxes provided next to each item.

Example Measurements:

Let’s assume the following measurements (these are hypothetical since I cannot physically measure the items):

- Crayon: 7.3 cm → Rounded to 7 cm
- Hot dog: 10.6 cm → Rounded to 11 cm
- Saw: 25.8 cm → Rounded to 26 cm
- Book: 15.2 cm → Rounded to 15 cm
- Paperclip: 2.9 cm → Rounded to 3 cm
- Pen: 14.7 cm → Rounded to 15 cm

Final Answers:

- Crayon: 7 cm
- Hot dog: 11 cm
- Saw: 26 cm
- Book: 15 cm
- Paperclip: 3 cm
- Pen: 15 cm

Explanation:

- Rounding: When rounding to the nearest centimeter, if the decimal part is 0.5 or greater, round up. If it is less than 0.5, round down.
- Accuracy: Make sure the ruler is aligned properly with the item to get accurate measurements.

Final Answer:

\[
\boxed{7, 11, 26, 15, 3, 15}
\]
