Description

How to Teach Building Shapes

This Using Objects to Construct New Shapes Worksheet helps students see that every shape is made of parts. When children build a shape out of straws and twist ties, each straw becomes a side or an edge, and each twist tie becomes a corner. Counting those parts is a hands-on way to learn what makes a pentagon, a hexagon, a cube, and a pyramid different from one another.

Students look at four straw-and-twist-tie models. Two are flat shapes and two are solid shapes. For each model, they count the straws and the twist ties and write each number in its box. Then they use the word bank to write the name of the shape on the line. It works well right after children build their own shapes with real straws and connectors, and it makes a quick check of what they learned.

What’s Included

  • One using objects to construct new shapes worksheet with four straw-and-twist-tie shape models
  • A word bank with cube, hexagon, pentagon, and pyramid
  • Count boxes for straws and ties plus a writing line for each shape name
  • A complete answer key with every count and shape name

Why This 2nd Grade Geometry Worksheet Helps Kids

First, counting straws and ties builds a clear picture of sides, edges, and corners, which is the language of geometry. Second, comparing flat shapes with solid shapes shows that a cube and a pyramid are made from the same simple parts as flat shapes. Third, naming each shape from the word bank strengthens shape vocabulary that students will use all year in 2nd grade geometry.

Ideas for Teachers and Parents

Hand out drinking straws and twist ties or pipe cleaners and let children build each model before they fill in the worksheet. Ask them to predict how many straws a shape will need before they count. As an extension, have students build a new shape with seven straws and describe it to a partner. This 2nd grade geometry worksheet also fits well in a math center or as homework practice with a family member.
