Fifth graders experience a instructional activity to investigate the methods for finding the area of a circle. They use the drawing of segments in order to visualize how a circle can be proposed of many parts. Then students brainstorm in...

Knowledge in Action! Today you will find out if the students are understanding the idea of decomposing and composing shapes with pattern blocks.

A guide to support parents as they work with their students in identifying, composing, and partitioning shapes.

In this series of STEAM activities, students will discover the concepts of geometry through shape exploration and the creation of choreographic sequences. Another activity in this module will allow students to identify shapes by applying...

These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

This computer tool allows students to compose and decompose shapes by making cuts and rearranging the pieces. The tool has an exploration section for learning exercises.

Students use pattern shapes to explore geometry and fractions, creating their own designs, or filling in outlines. As they work with the shapes students explore geometric relationships, think about angles, investigate symmetry, and...

First graders use their understanding of composing and decomposing shapes to cover a given area. Today's lesson is bringing together many of the geometric skills from previous lessons.

The students will make the connection between 2-D and 3-D shapes using modeling clay and geometric solids and participate in an interactive web lesson. Students will make predictions about what 2-D shape they think will be made when they...

Students will cut a square into four pieces, and then will put those pieces in an envelope for another student to put together. The purpose of this task is to give students a hands-on experience with composing and decomposing geometric...

The purpose of this task is to give students an opportunity to compose and decompose polygons to make rectangles. The students will be shown a picture and are asked to count how many rectangles they see. Explanations and examples are...

In this exercise, students practice decomposing figures to find area. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

For this lesson, students will explore self-portraiture by looking at classical portrait paintings, such as Diego Velazquez's La Infanta Margarita or Raphael's Portrait of Baldassare Castiglione. A close look at these works reveals...

In this exercise, students practice composing shapes. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

In this exercise, students practice decomposing figures to find the volume. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

In this exercise, students practice decomposing figures to find area. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

A guide to support parents as they work with their students in analyzing, comparing, and composing shapes.

Practice solving problems involving triangles, parallelograms, and composite figures. Exercises include decimals, fractions, and word problems. Area of circles is not included. Students receive immediate feedback and have the opportunity...

With this lesson, students will recognize and use the 4 basic shapes to create objects that they find in their environment. The students will then use their "shape creation" and recreate it on the computer.This lesson plan was created as...

Build a train by dragging shapes into a rectangle. Choose your level from easy (outline of shapes given) to hard (no outline of shapes).

In this interactive students click on one of the black statues to break them down into shapes; then they reconstruct the statue by putting the puzzle pieces together, which shows the animal that it represents and replaces the statues...

The purpose of this task is for students to decompose a figure into rectangles and then find the total area by adding the area of all of its smaller, non-overlapping rectangles. Aligns with 3.MD.C.7.d.

The purpose of this task is for students to compose two-dimensional shapes to create a composite shape using tangram pieces. The teacher will read "Grandfather Tang's Story" and the students will use tangrams to compose the animals from...
