How to Use This Pack

The unit test on multiplying and dividing decimals. 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 12 questions, one point each, and a Score line on its first page. Questions 1 to 11 are the Common Core part of the unit; question 12 (times and divided by 0.1 and 0.01) is for the states that teach it in 5th grade. The column problems and the long division sit on grids with room to write every step. No question asks a problem from the unit's exit tickets or the practice sheets. 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 3 and 9 have two parts and question 12 has four: give the point when every part is right, or score them by the part if you like. Question 12, at the bottom of the second page, is taught in 5th grade in some states only: give it if your class learns it and score out of what you give. The answer keys name each question's skill and show the work for the columns, the long division and the stories, 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 before multiplying, such as 4.9 × 3.1 is about 5 × 3, and to use the estimate to say where the decimal point goes.

Tips for Success

• Have students estimate first, then check that the answer is close
• Multiply as whole numbers, then count the decimal places in the factors
• In long division, write the point in the quotient right above the point in the dividend
• Count how many tenths or hundredths are in a number to divide by a decimal
• Use Form B as a retake after reteaching what was missed
