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.

In this estimation worksheet, 3rd graders study the 6 dimensions of a sketch of a house. Students estimate and measure 6 different sides of the house. Students check off each of 6 items that are longer than 1 decimeter.

Third graders add and subtract decimals.  In this third grade mathematics lesson plan, 3rd graders are given an imaginary $100 to purchase five Beanie Babies.  Students determine which five they would like to purchase and...

In this recognizing customary measurement concepts worksheet, learners estimate and measure objects, determine whether measurement of an estimate is sufficient, make lists of objects with specific measurements, and solve word problems....

Students practice measurement using real world objects. In this scavenger hunt for lengths lesson, students collaborate to measure with rulers, yardsticks, trundle wheels, and tape measures.  Students must estimate the length then...

Young scholars measure the size of an epithelial cell and to estimate the number of epithelial cells in a given area of the body. After watching a video on cells, student groups perform an experiment using a microscope to view some of...

Students examine uses for estimating, and round purchase prices to estimate total purchases in a simulated school store setting. They discuss what it means for an item to be on sale, and observe the teacher work through the process of...

Students develop their geography skills. In this Lewis and Clark lesson, students collaborate to calculate the time and distance of different segments of the expedition. Students compare their estimate to Lewis and Clark's.

Students estimate the total cost of a shopping trip. In this estimation lesson, students use three different techniques to estimate how much a shopping trip will cost.

Second graders investigate the physical properties of cantaloupe using their senses. In this life science activity, 2nd graders estimate the weight of their sample. They get it's actual weight and compare it with their estimate.

Students solve problems using various strategies. In this problem solving lesson, students read the book Swimmy by Leo Lionni. Students make fish swimming patterns, measure how many goldfish crackers it takes to make a handprint and...

Students collect data by conducting a survey of fellow classmates. They investigate the relationship between estimates obtained from samples and theoretical probabilities. Answer keys included.

Learners estimate angle measures in this this estimating angle measures lesson. They use an application on their graphing calculator that shows various settings involving angles and then they estimate the angle measure of a clock's...

With this estimating populations assignment, your class will learn about taking random population samples and calculating the average number of species in the samples to estimate the total population. Students use the given data to find...

Fifth graders examine the partial-quotients algorithm for finding the answer to a division problem.  In this partial quotients lesson, 5th graders demonstrate the process of division through a series of estimations....

Students examine and classify various types of rocks.  In this rock identification lesson, students complete a KWL chart about rocks and then read Let's Go Rock Collecting.  Students go on a walk to collect rocks and then...

Second graders explore estimation and place value. In this place value lesson, 2nd graders estimate and construct numbers while working with spider activities. Students use addition and subtraction to compare estimates. Resources and...
