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

Students explore how to estimate quotients and check their division with multiplication. They practice rounding the divisor and the dividend. Students compare the estimate to the exact answer and determine if it is reasonable.

Fifth graders solve division problems using partial quotients. In this long division lesson, 5th graders practice seeing division as a process of repeated subtraction and estimation. This lesson provides a script for the teacher.

Fourth graders perform probability experiments. In this math lesson plan, 4th graders complete a penny toss to evaluate and graph the combinations of outcomes. In a second activity, students draw M&Ms out of a bag and graph results....

Students gain an understanding of time. In this time lesson, students work together to recognize the difference between yesterday, today, and tomorrow, As well as months, hours, minutes, and seconds. Students brainstorm ideas of ways the...

Pupils perform operation with secant and tangent lines. In this calculus lesson, students find the derivative and relate it to the slope of a line. They differentiate between secant and tangent as they intersect a circle, using Cabri.

There are four irrational numbers that participants need to graph. Pi(π), -(½ x π), and √17 are easy to approximate with common rational numbers. On the other hand, the commentary describing the irrational number 2√2 is not...

Students use classified ads to select a career. In this math lesson, students convert the listed salary to an hourly, yearly, weekly and monthly rate. Students explain the process they used to find the various rates.

Students describe the difference between an estimate and a guess. They create reasonable estimates based on observation and hands-on activities. They synthesize estimated based on interaction with online activities.

Students work in groups to calculate the costs of a trip to Six Flags amusement park. For this domain and range lesson, students calculate the least and greatest amounts of money needed for tickets, food, souvenirs, and airplane tickets.

Students explore the concept of estimation. In this estimation lesson, students create their own estimation jars and fill them with objects of their choice. Students then count the exact number of objects and trade jars to...

Students gain the powerful tools of estimation, prediction, and averaging and discover the importance these tools have in daily living.

For this estimation worksheet, learners use a small snack food to complete 9 estimation activities. They describe the item they are estimating, make a first estimate, use more information, make a second estimate, acquire more information...

Students apply number and operation skills to learn how to spend a gift certificate. In this mathematical reasoning lesson, students use base 10 blocks as money and calculate how much money they have.

Students estimate what they can accomplish in a minute. In this estimation lesson, students guess how many jumping jacks or stars they can draw in a minute. They get timed and see how close they are to their prediction. 

In this estimation worksheet, students take a trip to a specific destination and guess how long they'll have to stand in line before it becomes their turn. Students use estimation in a variety of scenarios.

In this math worksheet, students complete 14 problems where they estimate money amounts and multiplication products using numbers with decimals. Examples are provided in this well-designed worksheet.

Students assign value to different shapes of pattern blocks, and estimate values and use process of elimination to determine values. In this pattern block values lesson plan, students trace each block on a worksheet and use 5 blocks to...

Students investigate various types of problems using whole numbers and decimals. They use a discussion format while working example problems to help create a baseline for further independent practice. The lesson plan also includes praise...

Students explore measurement. In this math instructional activity, students measure how far they can jump using blocks. Students compare the results when different sized blocks are used. Students estimate the distance jumped.

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...

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Compute fuel economy and gas mileage. Why? So you can teach rates and ratios, of course! Middle schoolers calculate the rate of miles per gallon for various vehicles. They research each vehicle, its mileage per gallon, and cost per...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...
