Middle Grades Math
Geometry
In this unit, students will explore how two-dimensional figures and their images are related under translations, rotations, reflections and dilations. Similarity and congruence will also be investigated. Students will identify the relationships between angles formed by intersecting lines and angles created when a transversal intersects parallel lines. Students will solve problems involving the area and circumference of a circle and investigate two-dimensional cross-sections of three-dimensional figures. Students will solve real-world problems involving surface area and volume of cubes, right prisms, cones, cylinders and spheres. Students will explore the Pythagorean Theorem and its converse.
This unit was developed from the Common Core State Standards. For more information download the unit guide (on the right) where the specific content standard is identified. There may be other CCSS that align to the activities as well that are not referenced on the guide.
