ExplorA-Pond:4th Grade Surface Area

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Cover some serious area in your geometry curriculum with this collection of worksheets. After first introducing the concept of area using the tiling method, this resource continues on to teach learners how to use the area and perimeter...

Help learners discover methods to estimate animal population. They will participate in a simulation of catching and tagging fish in order to estimate the fish population. They scoop and count goldfish crackers, record data, and use...

In a cross-curricular measurement and literacy lesson, your class will identify and compare cooking measurement instruments. They read a recipe and sequence a set of similar instructions in which the steps have been mixed up....

In this lesson students will practice finding the area of irregular shapes with right angles and understand that there are different methods for calculating area.

Build boxes using unit cubes to compare surface area and volume. The group performs multiple experiments to determine properties of volume, such as if it makes a difference which order the dimensions are multiplied in. Extensive...

Your geometers are used to finding the perimeter of a square or rectangle, so give them something different this time! With this lesson, small groups will receive a picture of a shoreline and calculate the perimeter. The website listed...

Students estimate the surface area of a pond using ratios and chance methods of estimation. They gain insight into how well estimations based on chance outcomes match the average of a maximum area estimation and a minimum area estimation.

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 irregular...

Fourth graders visit a real pond. They mark the pond's curvilinear perimeter using string. They measure the string to find the actual perimeter of the pond.
