# Math Article Series Assessment

## Assessment Objectives

The assessment is aligned to the Common Core State Standards for Mathematics – Grade 4 – Operations and Algebraic Thinking

4.OA.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

4.OA.2 Multiply or divide to solve word problems involving multiplicative comparison.

4.OA.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

25. Generate the first six numbers for a pattern that starts with 2 and has the rule add 4. What is the feature of this pattern?

## Answers

1. 35 is 5 times as many as 7 and 35 is 7 times as many as 5

2. 65 is 5 times as many as 13 and 65 is 13 times as many as 13

3. 39 is 13 times as many as 3 and 39 is 3 times as many as 13

4. 42 is 6 times as many as 7 and 42 is 7 times as many as 6

5. 100 is 10 times as many as 10 and 100 is 10 times as many as 10

6. 8 = 4 x 2

7. 153 = 3 x 51

8. 30 = 5 x 6

9. 18 = 9 x 2

10. 520 = 13 x 40

11. Let j = the number of jumps the students in Room 2 did. j = 3 x 1027, j = 3081, The students in Room 2 did 3081 jumps.

12. Let r = the number of cans the students in Room 2 collected. r = 2 x 139, r = 278, The students in Room 2 collected 278 cans. Let c = the number of cans the students in Room 3 collected. c = 139 + 278, c = 417, The students in Room 3 collected 417 cans.

13. Let b = the number of stickers Becky has, b = 39 / 3, b = 13, Becky has 13 stickers. Let c = the total number of stickers Amelia and Becky have together, c = 39 + 13, c = 52, Amelia and Becky have 52 stickers together.

14. Let j = the number of stickers John has, j = 2 x 19, j = 38, John has 38 stickers.

15. First, let t = the number of tours needed. t = 52 / 20, t = 2 remainder 12. The boat will need to make 3 tours.
