The Quantile® Framework for Mathematics, developed by educational measurement and research organization MetaMetrics®, comprises more than 500 skills and concepts (called QTaxons) taught from kindergarten through high school. The Quantile Framework depicts the 

developmental nature of mathematics and the connections between mathematics content across the strands. By matching a student’s Quantile measure with the Quantile measure of a mathematical skill or concept, you can determine if the student is ready to learn that skill, needs to learn supporting concepts first, or has already learned it. For more information and to use free Quantile utilities, visit www.Quantiles.com.

true or False?

1 Circle T if the equation is true. Circle F if the equation is false.

example 10 + 3 = 13 T F

a 6 + 6 = 12 T F

b 12 = 7 + 5 T F

c 12 – 8 = 4 T F

d 10 – 2 = 6 T F

e 10 = 6 + 4 T F

f 5 + 6 = 6 +5 T F

g 11 = 3 + 7 T F

2 Read the story. Circle T if it is true. Circle F if it is false.

a Sara had 8 cars. She got 7 more cars for her birthday. Now she has 15 cars in all.

T F

b Max made 13 cookies. The dog ate all the cookies. Max has 3 cookies left.

T F

3 Read the story. Circle the matching equation.

a There were 4 bugs in the garden. 9 more bugs came. How many bugs in all?

13 – 4 = 9 10 + 3 = 13 4 + 4 = 8 4 + 9 = 13

b 14 frogs were in the pond. 6 frogs hopped away. How many frogs were left?

14 + 6 = 20 14 – 6 = 8 14 – 4 = 10 12 – 6 = 6

4 Write a story on the back of this page to match this equation: 16 – 16 =0
