Activities that Build Number Sense
Have fun while building the number sense of young mathematicians with this list of ten-frame learning games. From developing cardinality and counting skills to learning place value and basic addition strategies, ten-frames are excellent...
Curated OER
Estimating Quotients
Put down those calculators! Show scholars they can solve division problems mentally using rounding strategies. They divide four-digit dividends by one-digit divisors, competing 26 problems in all. The first eight have some scaffolding...
Curated OER
Estimating Decimals
In this estimation worksheet, students learn to estimate with decimal numbers by using rounding or compatible numbers. There are 10 problems.
Curated OER
Estimate High and Low: Compatible Numbers
In this estimation activity, students read about compatible numbers and complete a chart, estimating quotients and determining if estimations were "over or under." Students then answer questions related to the chart.
Curated OER
Estimate Quotients
Fifth graders have to use division to solve problems in everyday situations. This worksheet on estimation and division has students practice these skills using real-life examples. The worksheet is part of the Houghton Mifflin math series...
Curated OER
Estimate Quotients: Reteach
In this estimating quotients instructional activity, students review how to estimate quotients using compatible numbers. Students then estimate the quotient for the division equations and tell what compatible numbers were used.
Curated OER
Estimating Quotients
In this estimating quotients worksheet, 4th graders estimate the quotient in 12 math problems and write the numbers they used on the lines provided.
Curated OER
Dividing By Two-digit Divisors
In this dividing by two-digit divisors worksheet, students working with a partner problem solve and calculate the answers to ten word problems and mathematical division equations.
Curated OER
Estimation: Compatible Numbers
In this estimation worksheet, students read real word problems and mentally estimate answers. Individually, they complete eight multiple choice problems using compatible numbers or rounding to determine their answers. Students evaluate...
Curated OER
Estimation 2: Sum and Difference
In this estimation worksheet, learners mentally solve eight multiple choice problems involving addition and subtraction. They arrive at their answers through the process of using compatible numbers or rounding. Students read story...
Curated OER
Compatible Numbers To Ten
Students solve both addition and subtraction facts and discover the relationship between adding and subtracting equations. Students read real life word problems, extrapolate needed information, and write equations to solve the story...
Curated OER
Estimation 4: Sum and Difference
In this estimation worksheet, young scholars read story problems, determine the correct operation, and mentally evaluate the problem by using compatible numbers or through the process of rounding. Students complete three multiple choice...
