## Lesson 6 - Sorting 2-D Shapes

To encourage students to have fun on the Web while learning about Sorting 2-D Shapes, here are some games and interactive activities they can do on their own or in pairs.

### Goals

Describe attributes of 2-D shapes.

Sort 2-D shapes by their attributes.

### Instructions for Use

Shape Sorter prompts students sort and classify shapes using a Venn diagram.

There are two ways to use Shape Sorter - Guess the Rule, or Make the Rule. Both ways students can use a single circle, two non-overlapping circles, or two overlapping circles. Click on either button at the left of the screen to choose which one to play.

To use Guess the Rule, the program creates a rule for students to try to figure out. Click and drag different colored shapes into the circle(s). Try to guess the rule based on which shapes and colors are accepted or rejected. Have students guess the rule from the pull-down menu and then click on the "Check Rule" button.

To use Make the Rule, have students make the rule for the circle(s) and then place the shapes in the appropriate location(s). Use the pull down menus to set the rule for each circle. Then click the "Set Rule" button to continue. Drag each of the shapes to their appropriate location in the Venn diagram. When the shapes are all in the correct locations, a message appears to indicate the game is finished.

Pattern Blocks lets students sort shapes by their attributes..

To use Pattern Blocks, click on a shape and drag it onto the workspace. Select a shape by clicking on it. Once selected, the shape can be moved to any location on the workspace. Click on the other tools on the top panel to select and drag, rotate, find more information about the shape, or to clear the workspace. To remove a shape, drag it to the recycling bin.
