Estimation - Multiplication and Division WORKSHEET
Interpret a fraction as division of the numerator by the denominator (a/b = a Ă· b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
Estimation - Multiplication and Division WORKSHEET DESCRIPTION
This worksheet focuses not only on estimation but also choosing suitable values for estimating answers to calculations. Section A asks learners to complete a large table where they need to choose suitable values to approximate the answer to a calculation as well as find the actual answer. Learners will need to be aware that sometimes rounding to 1 significant figure is not always the best method when estimating some calculations. Section B then provides six word problems involving estimation.
All worksheets are created by the team of experienced teachers at Cazoom Math.

Frequently Asked Questions
This worksheet goes beyond simple rounding rules by teaching students to make strategic decisions about which values work best for estimation. While many students automatically round to 1 significant figure, this 5th grade resource helps them recognize when that approach might not give the most reasonable estimate for multiplication and division problems.
