Seventh Grade
Geometry
Solve real-life and mathematical problems involving angle measure, area, surface area, and volume.
Lessons (11)
Introduces students to acute, obtuse, and right angles as well as relationships between angles formed by parallel lines crossed by a transversal.
Students learn about classifying angles by their measure and in relation to angles formed by two lines crossed by a transversal.
Comparing shapes with the same areas but different perimeters.
This lesson has students explore areas of rectangular and irregular shapes on a grid to help them understand the concept of area and the units in which area is measured.
Helps students understand there are a variety of ways to solve problems. This lesson also gives students practice in using various methods to find the areas of irregular shapes.
Introduces students to length, perimeter and area.
Introduces students to the concepts of surface area and volume.
This lesson teaches students how to find the surface area of non-rectangular prisms.
This lesson teaches students how to find the surface area of rectangular prisms.
This lesson teaches students how to find the volume of non-rectangular prisms.
This lesson teaches students how to find the volume of rectangular prisms.
Activities (6)
Practice your knowledge of acute, obtuse, and alternate angles. Also, practice relationships between angles - vertical, adjacent, alternate, same-side, and corresponding. Angles is one of the Interactivate assessment explorers.
Learn the relationship between perimeter and area. A shape will be automatically generated with the perimeter that you choose. Calculate the area of this shape. Area Explorer is one of the Interactivate assessment explorers.
Measure angles, distances, and areas in several different images (choices include maps, aerial photos, and others). A scale feature allows the user to set the scale used for measuring distances and areas.
This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter. Shape Builder is one of the Interactivate assessment explorers.
Learn the relationship between perimeter and area. A random shape will be automatically generated. Calculate the area and perimeter of this shape. Shape Explorer is one of the Interactivate assessment explorers.
Manipulate dimensions of polyhedra, and watch how the surface area and volume change. Parameters: Type of polyhedron, length, width and height. Surface Area and Volume one of the Interactivate assessment explorers.
