Rounding Teacher Resources

In this real-data worksheet, students use data from the 2008 Census Bureau to answer eight questions divided into four activities.  The topics covered include: place value, rounding, estimation, fractions, and percents.

Bring math home with this interative estimating worksheet! Scholars make educated guesses about the number of six household items: crayons in a crayon box, keys on a key ring, coins in a piggy bank, trees in the yard, pictures on the...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Estimation is a good way to build and assess a student's number sense. Watch as Sal uses estimation to solve a problem where he must determine how much 'Janelle' ran during a 4-day period. He calculates the exact amount and compares the...

The two rules of rounding are expertly-covered in this math PowerPoint. Young mathematicians are instructed to look at the number to the right of the place value they must round to. If the number is 0-4, the number stays the same. If the...

Kids might enjoy this dramatic presentation on estimating surface area. The fake Transylvanian accent is a bit distracting but the problem solving practices are sound. Dr. Crazy Pants rounds his decimal measurements then multiplies...

Rounding numbers can be fun using this game. Learners estimate and round numbers to the tens, hundreds, and thousands using this presentation. What a clever way to review this concept.

Teach young mathematicians that sometimes just getting close to the exact answer is perfectly fine, by using this collection of estimation worksheets.

Profit always seems to get everyone's attention. The same is true during a lesson on estimation. Learners use given information to estimate the cost of supplies for a painting job. They then develop a strategy for estimating the...

What is a quick comparison, and how can it help you estimate sums and differences? For this estimation worksheet, learners estimate fractions in addition problems. They complete four problems where they estimate the sums after reviewing...

Teach the class how to estimate by rounding to the nearest 10. They review the rules for rounding, try rounding a few numbers using a number line, then round on their own. This is a good introduction that explains how to round and why we...

Work on rounding, estimating, adding, and subtracting with a helpful math worksheet! Fifth graders study different sets of addition and subtraction problems, and after rounding each number to the leading digit, they estimate what the sum...

First graders estimate length and height of items. They read the story of Jack and the Beanstalk and discuss estimation of size. Students predict the length and height of figures. They use lines and numbers on the centimeter rod and tape...

By rounding, scholars find that adding money amounts becomes a breeze! They round two and three-digit numbers (with decimals) in these addition problems to get approximate sums. For each, mathematicians write the new addition equation...

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Teach your class a thing or two about making educated mathematical guesses. Learners read a passage that explains estimation and approximate and exact answers. They then respond to five questions about and related to the text.

Students complete a worksheet.  In this estimation lesson, students view various ties and estimate the number of objects or pictures on it.  Students complete a worksheet on estimation and then make their own tie pattern.

Estimating is an essential skill used in everyday life. This presentation explains how to apply prior knowledge about rounding numbers to estimating sums and differences. Example problems and assessment include large numbers, making this...

A good estimator usually has a good number sense. Make good estimators out of your class with this fun estimation activity. They review words that express estimation, estimate the number of three different sets, and then estimate the...

Select items to purchase from a store, add up the total cost, then estimate the total cost! Kids count out the money needed to make the purchase and pay for the items. An excelent way to connect real life math and estimation!

Learners use estimation to determine the answers to word problems by rounding whole numbers. In this estimation lesson plan, pupils compare and contrast solutions using the best answer.
