Description
This creating new shapes worksheet helps 2nd Grade students see how small shapes can be joined to build a brand new shape, and how to name that new shape by counting its sides. In second grade, children learn to sort polygons by the number of sides and angles they have: a triangle has three sides, a quadrilateral has four, a pentagon has five, and a hexagon has six. Composing shapes gives that skill a hands-on twist, because the new shape is built from pieces they already know.
How to Use This Worksheet
Each of the four cards shows a big shape made from smaller shapes such as squares, rectangles, and triangles. The lines inside show where the small pieces meet. Students count only the sides on the outside of the big shape and write the number on the sides line. Then they use the word box to write the name of the new shape: triangle, quadrilateral, pentagon, or hexagon. Each word in the box is used one time. Page two is an answer key, so checking work is quick and easy.
What’s Included
- Four cards with new shapes built from squares, rectangles, and triangles
- A sides line on every card for the number of outside sides
- A word box with four polygon names: triangle, quadrilateral, pentagon, and hexagon
- A full answer key on page two
Why This Worksheet Helps Kids
First, it shows children that shapes can be put together to make new shapes, a big idea in early geometry. Second, it teaches them to look past the inside lines and count only the outside edges, which builds careful attention to detail. Third, naming a shape by its number of sides prepares students for this 2nd grade geometry worksheet skill and for later work with angles, area, and fractions of shapes.
Ideas for Teachers and Parents
Before the worksheet, give children pattern blocks, paper squares, or paper triangles and let them build their own new shapes. Ask them to trace around the outside with a finger while counting the sides aloud. After the worksheet, challenge students to build a pentagon or a hexagon a different way and draw it. This creating new shapes worksheet also works well as a math center, a quick check after a geometry lesson, or extra practice at home.
