Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

The geometry resource investigates the area of irregular shapes. Detailed examples and practice exercises are included.

Practice finding the areas of complex shapes that are composed of smaller shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This resource has three sets of problems. Each set has six questions for finding area of irregular shapes formed by line segments. Select a problem set, then select a question. Fill in the blank with the correct answer for each problem....

Explore the world of prisms in this mini-lesson by learning what are prisms, definitions with shapes and examples, the difference between regular, irregular, right, and oblique prisms, the surface area of a prism, and the volume of a...
