Lesson Title:  Shapes and Solids

Software Applications:  PowerPoint & Word

Directions:
There are two different activities to reinforce geometry skills. In the first lesson the students will use a PowerPoint template to explore solids.

Lesson 1

Exploring Solids template
Slide 1: Students type their names.
Slide 2: Students click and drag the clipart solids under the proper category title.
Slide 3: Students find new examples of cones using clipart
(you may need to discuss shapes so that the students can have keywords for their search).
Slide 4: Students list the attributes of the solid. (i.e. number of faces, vertices, and edges. They can also list the shapes that make up the faces.)

Students can make copies of slide 3 and 4, change the name of the solid, and complete the information for the other solids mentioned in slide 2. To make copies, click on the slide on the left, go to edit copy, and then click on edit paste. If you need to move the slides, click on the number and drag it to where you want it.

Slide 5: Students choose two solids and put their names in the box. Then students can use one box to compare similarities and the other to compare differences.
Slide 6: Students read the clues carefully and drag the objects to their proper place.

Once the students are finished, the students can print the pages. To save paper, when the students click on print there will be a Print screen that appears. In the lower left hand corner, there is a box that says Slides. If you click on the arrow next to the word slides you can choose to print the slides as handouts. This will allow you to print up to 6 slides on each paper.

Before you go to the computer lab, open the templates, and save them to the Student Shared Directory so that all of your students can access the files.
You will  want to make the files read-only so that more than one student can open the document at the same time. Right click on the document, and choose properties. When the box opens, click in the box next to read-only. Click Apply and then click OK.

 

Lesson 2

The second lesson uses Microsoft Word to create a 2-dimensional drawing using the AutoShapes tools on the drawing toolbar.

Have the students open Microsoft Word. In the Menu bar have the students click on View - Toolbars - and make sure that there is a checkmark next to Drawing. If there is the students can click off of the dropdown box.

If the drawing tools are not activated, click on Drawing to open the toolbar. Most times the drawing toolbar will appear on the bottom of the page. You should see the word AutoShapes on the Drawing toolbar.

When the students click on AutoShape they will see several different categories to choose from. For this activity I would suggest using the Basic Shapes. Give the students a few minutes to click on different shapes and draw them on the Word document. To draw a shape, the students click their mouse where they want the shape to begin and then drag it to the place they want it to end.

Task: Create a 2 dimensional picture using the AutoShapes feature. (5-10 minutes)
Then have the students write instructions on how to create their picture using the proper vocabulary.
Depending on your class, you may want your students to create their picture on a separate piece of paper from their directions, or you may put the picture on the top half of the page and the description on the bottom half.
Have the students save their picture and directions to their personal directory.

Once all of the students have finished, print out the directions and pictures you can have students read each others directions and try to create each others shape.
(If the students are unable to recreate each others shapes, you can have the students work together to improve their directions and have other students try to draw their picture.)
