Use this resource to review 2-D shapes with your young mathematicians. Students will identify the names, number of edges, and number of vertices of common shapes as they work to fill in the blanks of this 2-D shape chart.
First grade geometry covers basic shapes, as well as an introduction to 3D shapes. Our team of curriculum experts designed the following guided lesson, which provides an overview of first grade geometric concepts and gives kids lots of opportunities for practice. If your child needs more support in a different format, check out the suggested first grade geometry worksheets.
Geometry in third grade introduces kids to the idea that shapes have different categories (rectangles, rhombuses, etc..) attributes (four-sided, etc...) and areas of different values. This lesson, designed by our curriculum experts, provides the guided instruction and practice that third graders need to conceptualize shapes in a deeper way. For more practice, download and print the third grade geometry worksheets recommended as part of this lesson.
What makes a trapezoid unique? How is it different from a hexagon or a pentagon? Use this resource with your students to practice identifying the characteristics of a trapezoid and comparing them to other 2-D shapes.
Use this resource to help your students develop their understanding of trapezoids and other two-dimensional shapes. Students will compare the attributes of trapezoids to those of other plane figures, such as triangles and ovals, in this geometry activity.
A key characteristic of trapezoids is that they have a set of parallel lines—lines that never intersect. Use this helpful geometry resource with your students to practice identifying parallel lines in trapezoids and comparing different 2-D shapes.
It’s time to practice finding perimeter! Use this geometry exercise with your students to give them practice calculating the perimeter of various trapezoids. Students will use addition to add up the lengths of the four sides of trapezoids.
Expand your child's shape vocabulary with these resources that test her on different kinds of polygons and geometric solids. These lesson plans, worksheets, and activities can be used to introduce students to the topic or review previous lessons, all while students work together to solidify concepts and get the individual practice they need.
