How can we estimate time? Have your young mathematicians make a clock. Then they compare and contrast types of clocks. They practice writing times in two different ways and make a book about telling time.

Learners make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

In this least squares learning exercise, students solve 6 different problems that include the least squares of numbers. First, they plot 3 points on the axes shown and draw in their best approximating line. Then, students estimate the...

Finding approximate solutions to word problems allows users to assess the reasonableness of their answers. In a well-paced lesson, the class rounds numbers to estimate the solutions. They explain their thinking and determine if the...

Learners celebrate the 100th day of school with a variety of math and language arts activities based on the number 100. They make books, count objects, and draw their predictions about life 100 years from now. They also estimate the...

Students participate in a instructional activity that has the intention of working on estimation skills. They use pumpkins to estimate the number of seeds are inside. They collect data for each pumpkin and compare it to the estimation....

Students, using a list made up of things from around the room; estimate the distance of one of the items on the list with one unit, record their prediction, and then actually measure items with non-standard measuring devise.

Students practice skip counting strategies, estimation, and higher number addition. They estimate the number of seeds in bell pepper, and count seeds in groups of tens and ones after the teacher removes seeds from the pepper.

Students investigate the water wars taking place in East Africa. In this global issues lesson, students watch video clips and read selected articles about the water shortages in East Africa. Students estimate their own average daily...

How can we estimate the answers when working with decimals? That's what the question is as the class reviews two-digit decimal addition. Have them estimate by rounding to a whole number either before or after they have completed their...

Students pace a Gunther Chain, a measurement used by foresters to determine distance and area. They discuss that pacing is individualized depending on age, gender, etc. They practice to find an average pace. Teams estimate, pace and...

Students describe and classify rocks that they have chosen. They estimate and find the mass of their rocks.

Sixth graders estimate surface area of a pond using a random number table.

Students create a survey to hand out to determine the best field day park. Using their local area, they select five parks, if possible, that meet the criteria and calculate the distance and estimated time travel. They use this...

Eighth graders view pictures that show many objects, estimate amount that they think they saw, and take class data from estimation to find the mean, median, mode, and range for the class.

Students study genetics and evolution. They evaluate a group of organisms and estimate their genetic relatedness. Then they use an online program to check the accuracy of their estimations and make a branching phylogenetic tree which...

In this function worksheet, students sketch the graph of a nonzero function, estimate the value of an infinite sum, and determine the derivative and slope of functions. This one-page worksheet contains approximately 6 multi-step problems.

Elementary schoolers learn about metric units and how they are used by engineers. They learn how engineers use the units to measure mass, distance, and volume. Then, they estimate measurements of units, and compare them to actual...

First, second, and third graders explore elapsed time through estimation and prediction. They work with a partner to estimate how long it will take to perform various tasks. One person uses a stop watch to time his or her partner...

Class members predict and count how many items need to be cleaned up in class while skip counting by 10s. They estimate whether having each child clean up 10 items will be enough to get the room ready for the next day. Everyone counts...

Little learners look at images inspired by classic fairy tales such as, gingerbread men, ducks, and shoes. They estimate how many they think are there then count to find out how close their estimate was.

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

A physical activity log will help your elementary students keep track of their activities. Your class will calculate the average number of physicaly active minutes per day. They compare with other students and then estimate the relative...

Practice makes perfect! Learners estimate the least squares fit line for a set of data. They understand error involved in least squares fit lines, and solve application problems using least square fit lines.
