Beacon Lesson Plan Library
It Figures!
Karen Castle Orange County Schools
Description
Students use a variety of materials to construct, compare and judge twodimensional figures.
Objectives
The student draws and classifies twodimensional figures having up to six or more sides.
Materials
Tablet paper
Tablet markers
Construction paper
Crayons
Rulers
Clay
Toothpicks
Preparations
1. Chart paper with predrawn Classification Tree
2. Construction paper
3. Overhead Projector
4. Prepared overhead sheets with 2 and 3 dimensional pictures
Procedures
A quick sketch activity uses an overhead projector and pictures of 2 and 3 dimensional figures displayed one at a time. A figure is flashed on the overhead and students proceed to draw the figure.
1. Introduce the lesson with a review of concepts taught in prior lessons. Teacher will hold up pictures of designated figures and review name of figure, number of sides, and if it is a 2 or 3 dimensional figure.
2. Use a quick sketch activity to have students describe, draw, and analyze 2 and 3 dimensional figures. This activity will serve as reviewing and accessing background knowledge of students.
3. Flash a picture of a figure on the overhead and students will have a few seconds to draw the figure they viewed. After students have time to draw what they see, teacher will show the actual figure and a quick discussion will ensue.
4. As a group, collaborate and brainstorm a list twodimensional figures. Write these words on the chart paper. (see attached file)
5. After brainstorming session, go over each word on the chart with students.
6. Randomly select a student to describe figure to teacher and proceed to draw figure on the board. Discuss name of figure and attributes with students.
7. Using background knowledge of figures, students will successfully describe shape to teacher.
8. Hand out construction paper, crayons, and rulers.
9. Students will draw diagrams of the twodimensional figures listed on class chart.
10. Pair students with a peer and have each student check drawings for accuracy.
11. Collect drawings. Use rubric as assessment tool. (See attached file)
12. Hand out another piece of construction paper.
13. Direct students to draw a classification tree labeled with 3 4 sided figures and 5 or more sided figures. (See attached file)
NOTE: A classification tree is used to classify information. (see attachment)
14. Independently have each student fill in the classification tree by drawing an accurate figure under the appropriate branch of the map. (Classifying)
15. Collect student classification trees. Use rubric as an assessment tool. (See attached file)
16. Together with students, review concepts taught by filling in a class classification tree (on chart paper) by asking volunteers to come up to chart and draw a figure under the correct part of the map.
Assessments
Use rubric to formatively assess the student’s ability to accurately:
*Draw twodimensional figures
*Classify twodimensional figures with up to 6 sides or more
Extensions
To modify lesson for ESE or ESOL, be sure to display examples of Thinking Maps on board and overhead; list vocabulary terms on board and overhead.
