Without measuring, can estimators determine which string is the longest? The shortest? There are two sets of strings here for learners to evaluate, circling the shortest in the first set and the longest in the second. Next, they eyeball...

Practice angle estimation with a worksheet. First learners estimate three angles within 15 degrees, then they measure and name each angle. A reference website is given for additional activities.

How can you complete a simulation when it is not practical to determine the probability of an event? Class members learn that in some situations, it is not feasible to find the probability of an event, but they can estimate it by running...

For this angles worksheet, students estimate angles to within 15 degrees, then measure and name each. A reference web site is given for additional activities.

How many hot dogs does Fenway Park go through in a year? Learners estimate answers to this question and more as they work through the task. Problems require participants to make assumptions and use those assumptions to make estimations.

Enrico Fermi, the physicist responsible for the first nuclear detonation, was known for his ability to estimate with little or no data. Use this task to have your classes practice their Fermi skills. They estimate the magnitude of three...

In this problem solving learning exercise, learners read and solve 6 story problems. Students explain why estimates or exact answers were used.

In this estimating tens worksheet, students use a picture of a group of penguins to estimate amounts, circle groups of ten, and find the total number. Students solve six problems.

In this estimating products worksheet, learners interpret data on the yearly diets of the average American, then solve 6 word problems where they must estimate products by rounding the larger factor to its greatest place value.

Using a number line worksheet, learners solve seven different problems using the shown number line in each. They estimate what number is selected on the number line in each problem and write it out.

In this estimating and counting learning exercise, students observe pictures of items in boxes, estimate and record the total amount, and then count and record the total. Students solve 4 problems.

It is about this big. An assessment provides three questions on the estimations of volume. Pupils determine the quantities needed and use dimensional analysis to arrive at estimations involving dollar bills, paint, and gasoline.

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

In this estimating practice worksheet, students sharpen their math skills as they learn how to make likely estimates and try the 2 extra practice activities.

I like this measuring with nonstandard units worksheet! Learners use paper clips and connecting cubes to estimate and measure real objects, and solve 17 problems.

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...

In this estimating lengths worksheet, students observe problems with pictures and lengths and choose the length that gives the best estimate. Students solve 9 problems.

How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.

In this estimation worksheet, students estimate numbers of items shown in pictures, then circle given groups of items, count and write totals. 

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.

In this estimate using tens worksheet, 2nd graders match three sets of toys with 3 jars by estimating using tens and reading the label on the jar.

In this estimate or exact instructional activity, learners complete word problems where they either estimate or find the exact number. Students complete 3 word problems.

For this estimation and rounding worksheet, students estimate sums or differences by rounding to the nearest hundred mile, then find the total distance from one given spot to another. 

In this length worksheet, students estimate how many cubes long items are, then measure, record and compare actual lengths. Houghton Mifflin text is referenced.
