Book Title: Great Estimations
Explore estimation with your math class. They will estimate how many Cheerios are in a box. Then count and group 50 Cheerios on a twist tie and attach groups to represent hundreds. They then discuss and practice skip counting and revise...
Scholastic
Study Jams! Estimate Whole Numbers
Watch animated slides as RJ explains how to round numbers to the nearest ten and thousand. Viewers then get a chance to try it themselves.
Curated OER
Estimate then Measure the Angle #4
In this angles worksheet, students estimate angles to within 15 degrees, then measure and name each. A reference web site is given for additional activities.
Curated OER
Estimate How Many Seeds Are In a Fruit or Vegetable
Help mathematicians estimate how many seeds are in a given vegetable or fruit. They are divided into pairs and estimate the amount of seeds in a whole fruit without seeing the inside. They then cut the fruit or vegetable in half and...
Balanced Assessment
Fermi Estimates II
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.
Balanced Assessment
Fermi Estimates I
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...
Curated OER
Problem Solving: Estimated or Exact Amounts
In this problem solving worksheet, students read and solve 6 story problems. Students explain why estimates or exact answers were used.
Curated OER
Estimate Tens
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.
Curated OER
Estimate Products
For this estimating products worksheet, students 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.
Curated OER
Estimate and Compare Data
Seventh graders explore the values that are used in order to describe data that is collected or given. They compare data using the statistical analysis provided by finding the mean, median, and range.
Curated OER
Estimate on a Number Line
Using a number line activity, 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.
Curated OER
Estimate and Count
In this estimating and counting worksheet, students observe pictures of items in boxes, estimate and record the total amount, and then count and record the total. Students solve 4 problems.
Curated OER
Estimate Weight In Metric
Learners brainstorm words that describe the weight of objects. They pick up objects and estimate the weight. Afterward, students find the exact weight and compare U.S. units of weight to metric units. In groups, learners create a chart...
Concord Consortium
Fermi Volume
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.
Mathed Up!
Scatter Graphs
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...
Curated OER
Reasonable Estimates
Help pupils explore estimation. They will make estimates and discuss when you might use an estimate. Then they discuss if their estimates are reasonable.
Curated OER
Everyday Mathematics: Ballpark Estimates
In this estimating practice activity, students sharpen their math skills as they learn how to make likely estimates and try the 2 extra practice activities.
Curated OER
Estimate, Solve, and Check
Young scholars estimate, solve, and check a series of addition and subtraction number and word problems. They write their estimates on a recording sheet, compute and write the answer in the next column, and check their answer with a...
