Shodor Interactivate: More or Less Estimator

Tell the story of the math. Given a graph of a linear system, learners write a story that models the graph before crafting the corresponding functions. Graphs intersect at an estimated point, allowing for different variations in the...

This activity allows the user to practice estimation skills by determining if a given amount is more or less than the number of objects shown, the length of a curve, or the area of a shape. An interactive activity and teacher resources...

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 practice estimation skills. Students use three types of estimations: counting, length, and area. An interactive activity and teacher resources are included.

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.

The Shodor Education Foundation provides this lesson plan to introduce young scholars to the concepts of probability. Students learn about the definition of, outcomes in, and calculations of experimental probability. Young scholars use...

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...

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.

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...
