Uncover strategies for finding areas of composite figures. The 23rd lesson in a 29-part module has young mathematicians decompose figures to find total area. Figures decompose to rectangles and circular regions.

Investigate perimeter and area of polygons! In this measurement lesson, learners use index cards to create rectangles and trace their hand to estimate its area and perimeter.

All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...

Remodeling projects require more than just a good design — they involve complex fractions, too. To determine whether a tiling project will fit within a given budget pupils calculate the square footage to determine the number of...

The asteroid is getting closer and the question is whether the state of Alabraska is large enough for the shelter calculated in the previous activity. Teams determine the scale of their project and then use the scale on the map to...

In this area and perimeter instructional activity set, learners determine the area and perimeter of 120 rectangles when they are given the length and the width of each. They write the answers with the proper labels.

Students practice using the formula to calculate the area of a square or triangle. They participate in large group guided practice using simple area of squares problems then complete a series of problems calculating the area of rectangles.

In this length and width learning exercise, students find either the length or width of a rectangle with the area and other known measurement given. Students complete 4 problems.

Seventh graders review the concept of finding the areas of a rectangle. This lesson uses the classroom as a real life application for the formula of area. They measure classroom in order to compute the area.

Students study area and quadrilaterals. In this multiplication and area lesson, students use Polystrip models to change rectangles to form different parallelograms. Students find the area of the models use a Geometer Sketchpad to find...

Seventh graders practice finding the area and perimeter of polygons. In this polygon area lesson plan, 7th graders brainstorm shapes and take a walk to locate shapes. Students record properties of shapes and use various shapes to...

In this geometry worksheet, 10th graders use algebra to solve geometry word problems involving the perimeter of a rectangle. The one page interactive worksheet contains eight questions. Answers and hints are included. 

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...

In a straightforward assignment, learners simple calculate the area or perimeter of 14 rectangles. For the first six, a rectangle is drawn with the lengths of the sides provided. For the next six, lengths of sides are simply listed to...

Learners divide a poster board so everyone gets the same amount of area to decorate. Youngsters talk about the different ways to divide a rectangle. They measure their lines to make sure that each piece is equal and then decorate their...

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...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

What is the area? Because there is only one problem here with a detailed explanation below, consider projecting this as an all-class warm up. Learners examine a rectangle split into 12 squares. They know that each unit is three...

Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...
