Young scholars perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.

Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.

Students use ratio and proportions to solve problems. In this geometry lesson, students apply ratio and proportions to real life scenarios.

Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

10 this geometry instructional activity, learners identify the different angles created by polygons and name the shape created based on the number of sides. There is an answer key.

Students measure the perimeter and area of their polygons. In this geometry lesson plan, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

Students prove the theorem of Pythagoras. In this Pythagorean Theorem lesson, students define the different parts of a right triangle. They use the Pythagorean Theorem to solve for the missing sides and angles of a right triangle.

In this bedroom redecoration project, your young mathematicians become interior designers. They plan, draw, and determine finances for the project. They apply their knowledge of working with decimals, geometric shapes, and problem...
