Third graders estimate and measure the length of a whole color-segmented, candy gummy worm. Then, as students bite off each segment, they estimate, measure and record findings in an activity log.

Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

In this compound shapes worksheet, students solve 40 problems in which the area and perimeter of compound shapes is calculated. There are instructions and examples on this page, which is intended to be used on-line, but can be completed...

In this cumulative math review learning exercise, 5th graders respond to a variety of review questions which can be used for practice testing. Students answer 8 questions pertaining to charts and graphs, word problems, and equations.

Students develop an appreciation for complex structures in nature. They observe patterns in nature in relationship to the Real World. Students use observation skills to assist in problem solving. They show comprehension of the concepts...

Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Young scholars are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Students analyze and demonstrate how a circle can be measured in square units and examine how diameter, circumference and radius are related.

Students discuss current knowledge of pixels. They listen as the teacher explains their importance in picture clarity. Students view the "Pixel Mosaic Animated Movie." Students receive pieces of pictures and matching tiles which...

Double the dimensions, quadruple the surface area. Pairs build similar prisms and compare the ratios of their surface areas and volumes to the ratio of the heights. Given two similar cones, partners determine the ratios of the lateral...

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to find the perimeter of a shape using a grid.

Find the area and perimeter of quadrilaterals using their coordinates. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Drawings and discussion of several methods to estimate the area of an irregular shape, like the state of Texas.
