Shape Up Exercise

Barbara Estevez

Description

This activity allows students to use technology to demonstrate mastery of congruent and similar shapes. Students use software like MS Word 97 or higher with gridlines to draw the shapes and manipulate them for congruency and similarity.

Objectives

The student knows congruent and similar figures.

Materials

-Computers (lab setting is preferable but can be done with less)
-Microsoft Word 97 or higher
-Printer
-Overhead
-Transparencies
-Vis-a-Vis pens
-Terminology sheet created by teacher (see teacher preparation)
-Printer paper
-Graph paper

Preparations

1. Create geometric term list to include the name and definition for pentagon, hexagon, octagon, and triangles (equilateral, isosceles, and scalene) and 2 different quadrilaterals, leaving a place for students to draw the corresponding example for each term. (You can use the included student worksheet and key or create your own).
2. Make sure there is enough graph paper for 2-4 pages per child.
3. Turn on computer(s) and printer.
4. Make sure there is paper in the printer.
5. Have overhead with transparencies and colored pens ready.

Procedures

1. In the classroom setting, distribute a list of terms for various geometric shapes. (teacher-created terminology sheet)

2. Use the overhead to demonstrate examples of the different shapes.

3. Students will draw each example by the corresponding shape term on their sheets to use as a reference. Walk around and make sure students are drawing the shape correctly.

4. Introduce the concept for congruency and similarity by modeling them on the overhead with each shape.

5. Distribute graph paper (2-4 pages per student) and model how to draw the figures so that the student can show congruency and similarity.

6. Have students draw the shapes to show congruency and similarity for pentagon, hexagon, octagon, triangles (equilateral, isosceles, and scalene) and 2 different quadrilaterals based on the teacher demonstration.

7. If there are no computers available, have students put their names on their papers before they submit them for assessment. They will need to label the figures, including the congruent and similar figures. Assess the drawings according to the instructions in the assessment.

8. If computers are available, demonstrate how to open MS Word 97 and add gridlines from the Draw feature.

9. Demonstrate how to add geometric shapes from Basic shapes found in Autoshapes.

10. Demonstrate how to use the flip/rotate feature found in Draw to show another perspective.

11. Demonstrate how to enlarge and reduce the shape size.

12. Students create their own paper grids and show congruency and similarity for pentagon, hexagon, octagon, triangles (equilateral, isosceles, and scalene) and 2 different quadrilaterals different based on the teacher demonstration. These will need to be labeled.

13. Students can use the flip/rotate feature to show a different perspective.

14. While students create their Shape Up Exercise, move around every station to help with student feedback and problems.

15. Students type their names on the final documents and print them for assessment purposes.

Assessments

Assess each student's computer work or drawing for: Printed student Shape Up Exercise document showing congruency and similarity for pentagon, hexagon, octagon, triangles (equilateral, isosceles, and scalene) and 2 different quadrilaterals. Labels must be included. For students who are having difficulty, offer feedback and assistance since this is a formative assessment in this lesson.
