Shodor Interactivate: Estimator

This applet game for two allows you to practice estimating at several different levels of accuracy. You can choose whole number addition, multiplication, percentages or any combination of the three.

This lesson plan is designed to help students learn to make estimates. Resources are linked to help support the teacher and offer exploration and practice to students.

Use this applet to practice your estimating skills comparing length, area, counting or a random sampling of those topics. You can also adjust the difficulty and the precision needed. The applet also lets you know how close you are to the...

This activity allows the user to compare to quantities by estimating. Students use three types of estimations: counting, length, and area. An interactive activity and teacher resources are included.

Practice your estimation skills by comparing the number of objects shown, the length of a curve or the area of a shape to a given number. Your choices are "greater than" or "less than".

Fit functions to data by using an interactive app. Individuals plot a scatter plot and then fit lines of best fit and regression curves to the data. The use of an app gives learners the opportunity to try out different functions to see...

Students explore the concept of estimation. In this estimation lesson plan, students discuss making estimates through teacher led discussion. Students use the Internet to complete an activity where they must estimate the length of lines.

Pupils solve problems with percents, decimals and fractions. In this algebra lesson, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.
