Middle schoolers classify angles. In this angles lesson, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Middle schoolers participate in...

Sixth graders identify and measure right, acute, obtuse, and straight angles. In this geometry lesson, 6th graders review the definition of each angle and are shown examples of each specific angle. Students use toothpicks, gumdrops, and...

Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Learners construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...
