FOR 3RD GRADE

PREVIOUSQuestion 1: Answer is B

 

Solution: Correct Answer B

3rd grade students are expected to demonstrate proficiency representing fraction using number line. They are also expected to demonstrate proficiency in comparing 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.
