In this geometry learning exercise, 10th graders arrange pennies in the form of a triangle. They then remove three pennies to rearrange the shape of the triangle and diagram it. An answer key is provided.

First graders explore shapes. In this geometry instructional activity, 1st graders make shapes with geo-boards, use play-dough to make three-dimensional figures, and make a shape book using pre-cut shapes.

Students identify attributes of different geometric shapes. In this geometry lesson, students view a  PowerPoint presentation on shapes and use attribute blocks to examine the corners and edges of each shape. Students work together...

Learners explore geometry by analyzing different shapes. In this shape identification lesson, students discuss the characteristics that make certain shapes unique and the same characteristics that cause shapes to look the same. Learners...

In this geometry worksheet, learners find the area and perimeter of 6 different compound shapes containing squares, rectangles, triangles, and half circles. 

In this geometry worksheet, students solve the area of 2D shapes starting with squares, rectangles, parallelograms, triangles, rhombi, trapezoids, circles, and ending with area of shaded regions. There are 20 questions.

Geometry is full of shapes, figures, and corresponding things here and there. The guide shares all of the key pieces of geometric information in a nicely color-coded and labeled sheet. 

What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...

Drawing triangles is easy, even if you have to calculate the exact length of its sides. Scholars use the Law of Cosines to find missing sides of triangles. An interactive helps them check their answers.

In this rectangles and shapes worksheet, students complete a variety of exercises including counting the number of faces on a solid object, coloring solids to match nets and coloring plane shapes. Students check their answers online as...

Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Have your learners practice finding the perimeter and area of geometric shapes using this resource. While just a simple review, this could be a wonderful way to solidify the concepts in their minds.

Investigate the area and perimeter of polygons in this geometry lesson plan. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape...
