  • Multiply multiples of 10, 100 and 1,000, and write powers of ten with exponents
  • Round each factor to estimate, and decide whether an answer is reasonable
  • Fill in area models and break a factor apart into partial products
  • Multiply with the standard algorithm, up to 4-digit by 2-digit and 3-digit by 3-digit numbers
  • Solve a one-step and a two-step multiplication story
  • Answer keys name the lesson and skill of every question

Skills Covered

How to Use This Pack

The unit test for the third unit of 5th grade, multiplying whole numbers. Pages 1 and 2 are Form A. Pages 3 and 4 are Form B: the same questions in the same order with different numbers, for a retake, a make-up or a second seating. Each form has 13 questions, one point each, and a Score line on its first page. The pre-check and the unit review are packs of their own.

In the Classroom

Give Form A the day after the unit review. Questions 1, 2 and 3 hold more than one problem, and the area models and the questions that break a factor apart (5 and 7) ask for several parts: give the point when all are right, or score them by the part if you like. The keys show one way to split a factor and one way to work the two-step story; other ways that reach the same answer are right too. No question asks a problem from the unit's exit tickets or the practice sheets. 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 to estimate first (round each factor to its greatest place), then multiply and see whether the answer is close to the estimate.

Tips for Success

  • Think of 40 × 300 as 4 × 3 with three zeros after it
  • The exponent on a power of ten counts its zeros
  • Split a factor by place value, then add the partial products
  • Write each regrouped digit small, above the next place
  • 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:

  • 4.OA.A.3 Solve multi-step story problems with whole numbers and all four operations, deciding what remainders mean, writing equations with a letter, and checking by estimating.
  • 5.NBT.A.2 Explain why multiplying or dividing by 10, 100 or 1,000 adds zeros or moves the decimal point, and write powers of 10 with exponents.
  • 5.NBT.B.5 Multiply whole numbers with many digits fluently, using the standard written method.
