Features

  • Forms A and B ask the same questions with different numbers
  • Write a times as many sentence as an equation, and an equation as a sentence
  • Times as many stories with a strip diagram, and stories that divide
  • Times as many or how many more, with the same numbers
  • Factor pairs from rectangles and in a T-chart, and whether one number is a factor of another
  • Skip count to find multiples, circle multiples, and circle the prime numbers
  • The last two questions (facts with 11 and 12, and the greatest common factor) are for the states that teach them in 4th grade
  • Answer keys name the lesson and skill of every question

Skills Covered

  • Multiplication as comparison
  • Times as many stories with strip diagrams
  • Times as many or how many more?
  • Factor pairs from rectangles
  • Every factor pair of a number to 100
  • Multiples
  • Prime and composite numbers
  • Facts with 11 and 12, and the greatest common factor

How to Use This Pack

The unit test on times as many, factors and multiples. Pages 1 and 2 are Form A. Pages 3 and 4 are Form B: the same questions in the same order with different numbers and facts, for a retake, a make-up or a second seating. Each form has 12 questions, one point each, and a Score line on its first page. Questions 11 (facts with 11 and 12) and 12 (common factors and the greatest common factor) are for the states that teach them in 4th grade. The pre-check and the unit review are packs of their own.

In the Classroom

Give Form A the day after the unit review. Most questions have two or more parts: give the point when every part is right, or score them by the part if you like. Question 11 is for Florida, Oklahoma and Virginia, and question 12 for Virginia: leave out the ones your class does not learn and score out of what is left. Factor pairs can be written in either order, and a story can have more than one right equation; the keys show one way. The answer keys name each question's skill, so a missed question points to the lesson to reteach.

At Home

Use Form B as a check after the unit. Ask your child for every way to make a rectangle from 24 squares, and whether 24 is prime or composite.

Tips for Success

  • Ask "times as many, or how many more?" before solving a comparison story
  • Have students draw a strip diagram for each times as many story
  • Find factor pairs in order, starting with 1, so none are missed
  • Remember that a prime number has exactly two factors
  • Use Form B as a retake after reteaching what was missed

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 3.OA.C.7 Multiply and divide to 100 fluently with strategies, and by year's end instantly recall every product of two single-digit numbers.
  • 4.OA.A.1 Read a multiplication equation as a comparison (24 = 3 × 8: 24 is 3 times as many as 8) and write comparisons as equations.
  • 4.OA.A.2 Multiply or divide to solve story problems that compare amounts (times as many), using drawings and equations, and tell them apart from comparing by adding.
  • 4.OA.B.4 For numbers 1 to 100, list factor pairs, spot multiples of one-digit numbers, and sort numbers into prime and composite.
