FOR 3RD GRADE

Correct Answer . Read the explanation below

NUMBER AND OPERATIONS is a common core content. It means you will use this acquired knowledge from 3rd grade to high school

The AZ Department of Education Mathatematics Standards expected 3rd grade students to master how to represent fraction using number line. They are also expected to master how to compare fraction using benchmark.

3rd grade students ? Do you know how to draw a benchmark fraction or number line?

Step 1. To draw the 1/2 (halves ) benchmark fraction. First draw a straight line.On the left hand side of the line make a tick mark then number it 0 (zero) and again on the right hand side of the line make another tick mark then number it 1 (one).

Step 2. 1/2 (halves) benchmark fraction is actually telling you to divide the line you drawn into half.See the picture shown below and copy how to draw the halves (1/2) benchmark.

3rd grade students. It's time to test your understanding on how to draw a benchmark fraction. Are your ready?

Now draw the third (1/3) benchmark fraction. You can copy the drawing above if you need help. What do you notice about the total length of halves (1/2) benchmark fraction and the thirds (1/3) benchmark fraction? You are right. They have the same total length.


Now draw the fourths (1/4) benchmark fraction.What do you notice about the total length of the halves (1/2) benchmark fraction, the thirds (1/3) and the fourths (1/4) benchmark fraction? You are right. They have the same total length.


Now draw the fifths (1/5) benchmark fraction. What do you notice about the total length of the halves (1/2) benchmark fraction, the thirds (1/3), the fourths (1/4), and the fifths (1/5) benchmark fraction? You are right. They have the same total length.


Now draw the sixths (1/6) benchmark fraction. What do you notice about the total length of the halves (1/2) benchmark fraction, the thirds (1/3), the fourths (1/4), the fifths (1/5), and the sixths (1/6)? You are right. They have the same total length.


Now draw the eighths (1/8) benchmark fraction. What do you notice about the total length of the halves (1/2) benchmark fraction, the thirds (1/3), the fourths (1/4), the fifths (1/5), the sixths (1/6) and the eighths (1/8) benchmark fraction? You are right. They have the same total length.


Now draw the tenths (1/10) benchmark fraction. What do you notice about the total length of the halves (1/2) benchmark fraction, the thirds (1/3), the fourths (1/4), the fifths (1/5), the sixths (1/6), the eighths (1/8), and the tenths (1/10) benchmark fraction? You are right. They have the same total length.


Draw the 1/16 (sixteenths) benchmark fraction.
