About this worksheet

Is it proportional?. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can tell whether a table is proportional by finding the amount for 1 in every row.
I can tell whether a graph is proportional: a straight line through (0, 0), even when I only see two points.
I can tell a steady add (+2 each time) from a steady multiply, and I know a starting amount stops it being proportional.

Standard: 7.RP.A.2a

Words to know

proportional: Two amounts where one is always the same number of times the other.

the amount for 1: How much of the second thing goes with exactly 1 of the first, in a row.

the 1 row / each row: Divide second by first in every row; proportional tables get the same answer every time.

origin, (0, 0): The graph's corner: none of the first thing goes with none of the second.

steady adding: The same amount is added each row. It looks regular but is not multiplying.

Common mistakes

Your child saw both columns go up by the same amount each row and called it proportional.

Your child checked the first row (or two) and stopped.

Your child said no because the second column grows by a different amount than the first.

What to say

Ask: in each row, how many of the second thing go with exactly 1 of the first? Is it always the same?

Ask: does the same rule still work in the last row?

Ask: if you double the first number, do you double the second? Different jumps are fine when it is multiplying.
