In this activity, the students will investigate a variety of plants and animals common to the Amazon through research. They will determine the plant or animal characteristics that make them edible or useful for the trip and learn to categorize them by comparing similarities and/or differences.

Helping kids learn what makes different media choices healthy or not is a good start. But how do we help them actually make responsible choices in the real world? Give your students the opportunity to create a personalized media plan.

The objective of this module is to show the many ways you can quickly and easily find OER materials in OER Commons. This module, “Finding OER Materials,” is activity-based; you'll be guided through the process of finding OER materials you can start using in your teaching and learning.

In this task students have the opportunity to construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).

This real world problem is appropriate for mental mathematics and students should be encouraged to think through the solution mentally.

The purpose of this task is to give 4th grade students a problem involving an unknown quantity that has a clear visual representation. Students must understand that the four interior angles of a rectangle are all right angles and that right angles have a measure of 90_ and that angle measure is additive.

This short video and interactive assessment activity is designed to teach fourth graders about finding the adjusted rate - word problems.

This tasks examines how to calculate the area of an equilateral triangle using high school geometry.

This short video and interactive assessment activity is designed to teach fourth graders about finding the capacity of water with illustrations (metric units).

This short video and interactive assessment activity is designed to teach third graders about finding the expression not matching a given number.

This short video and interactive assessment activity is designed to teach fourth graders about finding the expression not matching a given number.

This short video and interactive assessment activity is designed to teach fourth graders about finding the incorrect equations.

This short video and interactive assessment activity is designed to teach fourth graders about finding the number from figure patterns.

This short video and interactive assessment activity is designed to teach fifth graders about finding the total amount of liquid in liters and milliliters.

This short video and interactive assessment activity is designed to teach fifth graders about finding the total using division - word problems.

This task helps students solidify their understanding of linear functions and push them to be more fluent in their reasoning about slope and y-intercepts. This task has also produced a reasonable starting place for discussing point-slope form of a linear equation.

This task "Uses facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure (7.G.5)" except that it requires students to know, in addition, something about parallel lines, which students will not see until 8th grade.

This task asks students to solve addition and subtraction equations with different structures so that they are able to see the connections between addition and subtraction more easily.
