Students calculate the surface area of polygons. In this geometry lesson, students use spacial reasoning to find the answer to their problem. They analyze solids and create formulas to estimate the measurements of the area.

In this math worksheet, students work in groups to estimate the area of the ellipses using the grids. Then they estimate the arclengths of the ellipses.

Second graders, in groups, estimate amounts in various jars. They sort each jar from least to greatest amount.

Third graders investigate liquid measurements by estimating how many cups it takes to fill containers. The students predict the liquid measurements and then find the actual amount using the water in a bucket. Students then compare...

In this Euler's method instructional activity, students use Euler's method to determine one-second time intervals in a rate problem. They explore functions to estimate rate changes in small time intervals. This two-page instructional...

In this quadratic equation learning exercise, students solve quadratic equations by graphing. They identify the exact roots or state consecutive integers between which the roots lie. This one-page learning exercise contains seven...

Young scholars estimate the amount of money they have in groups of pennies, nickels, and dimes. In this money lesson plan, students then count up the amounts they have and exchange money amounts.

Twelfth graders experiment with a projectile that is launched horizontally after a demonstration and small discussion about two pennies, one dropping from a table top and the other being slide off the top and hitting the ground at about...

Single-step addition or subtraction operations are applied in order to solve these 12 simple equations. An answer key is available, not so much for you, but perhaps to be used by learners as a self-correction tool. Note that the...

In this prealgebra activity, pupils perform addition, subtraction, multiplication, or division operations to solve for an unknown. There are 12 problems to be solved. Use this as a quiz to assess how well your class is grasping the skill...

This printable contains 12 basic equations to be solved. The first one is worked out as an example, and the answers for all can be found by clicking on a "Show Answers" box found on the website. The publisher has identified this as...

Students use estimation skills to calculate distance traveled and then calculate walking rate traveled in MPH.

Twelve very simple equations are presented for learners to solve. What is the value of x? What is the value of n? Individuals apply operations to find the answers. You will find the final answers by clicking on the appropriate box at the...

First graders distinguish between an over-estimate and an under-estimate. They estimate the number of beans that can be held in a hand, organize data and actual findings.

Learners estimate how many peas fit in a container. In this science lesson plan, students calculate the weight of a pea and record it. They use this data to calculate how many peas fit in a human brain.

Fourth graders are given a map of Indiana and have to plan a road trip including at least two major points of interest with 100% accuracy. The students estimate the distance between their two chosen locations with 100% accuracy.

Second graders choose estimation strategies in real-world problem situations and explain the choice. They work in groups of five using three different estimation methods to find out how many words are on a page of text.

In this counting activity, students read about counting and when it is appropriate to find an exact count of something, versus counting by ten to find an estimate. They then read 10 items that can be counted and indicate whether they...

In this math worksheet, students learn to subtract whole numbers and decimals. Students are given step by step directions on how to solve one sample problem, then complete 5 examples on their own. Example: 6.57 - 3.28. There is...

Fifth graders use estimation to solve problems and assess the reasonableness of their answers. They may use an odometer, a map with a legend, MapQuest, or a map without a legen. They estimate 4 to 5 different scenarios.

Students explore the problem of percentages. Students find a given fraction or percentage of a quantity. Students devise and use problem solving strategies on problems explored.

Eighth graders complete math problems given in this lesson, where they find the perimeter and area of specific figures. They estimate the perimeter and area of shapes and figures and then complete the mathematical formula to find the...

Fifth graders create a timeline of the most important dates and events involved in the history of electricity. Each student researches one scientist and designs and illustrates a piece of a poster board for the timeline.

Students label the parts of a wheat plant on a worksheet. In this Egyptian farming lesson, students thresh a wheat stem and estimate the amount harvested. Students research Ancient Egypt online.
