Introduction:
This lesson is designed to teach students how to identify geometry terms, shapes, classify angles, lines and to determine the different between edges and vertices.
Vocabulary Words:
Students will identify vocabulary words such as ray, angles, right angle, acute angle, obtuse angles, triangles, intersecting lines, and perpendicular line, by constructing or drawing them.
Purpose:
To assess students knowledge of vocabulary words, geometry terms, classifying angles and lines.
Objectives: Students will recognize angles and lines, identify three-dimensional shapes, determine the difference between edges, faces, vertices; understand the difference between a prism and a pyramid
Materials:
Procedures:
Hand out packets of shapes. Post pictures of shapes on the board and no charts. Discuss what a three-dimensional shape is and the difference between two and three-dimensional shapes. Students will construct three dimensional shapes from the hand out packet . Once everyone has constructed their shapes (this takes a while) have them to explain the concepts; of edges, and vertices using the models. Review the lesson.
Assessment: Assessment is on-going throughout the lesson. 100% participation is required throughout the lesson, because the students have to cut and paste together their shapes and construct models of triangular pyramids and prisms. This is a great lesson to do with students, because they love constructing things.
