IEL Tip Sheet: Path to Math: Geometric Thinking for Young Children About
Children ages 3–5 are beginning to learn about shapes, spaces, and locations—basic concepts of geometry. They use geometric thinking when they build with blocks, assemble a floor puzzle, or play a target game. Here are some ways to engage preschoolers with geometry. (See Illinois Early Learning and Development Benchmarks 8.A.ECa Sort, order, compare, and describe objects according to characteristics or attribute(s).View sample lesson plan and 9.A.ECa Recognize and name common two- and three-dimensional shapes and describe some of their attributes (e.g., number of sides, straight or curved lines).–9.A.ECe Think about/imagine how altering the spatial orientation of a shape will change how it looks (e.g., turning it upside down)..)
Use the language of geometry.
- Describe objects by their shape when you talk with children. “You found a square piece of fabric.” “Kaya used two cylinder blocks in her tower.”
- Use words such as side, solid, surface, point, straight, curve, inside, flat, top, angle.
- Look at art work together and talk about how artists use lines and shapes. Help children recognize lines and shapes in their own drawings.
- Help children ask and answer thought-provoking questions. “If Mario places these three rods next to each other, what shape will he have?” “How can you tell this is a circle and not a square?” “What could you do if you wanted to turn the square on the geoboard into a triangle?”
Make geometry a part of daily routines.
- Have children line up to go places. Ask them who is at the beginning or end of the line.
- Label shelves with the outlines of items that should go there. Children can put away toys and supplies by matching each item to its outline.
- Help older preschoolers make comparisons of shapes and sizes. “Will that paper rectangle fit inside this round basket?”
Plan activities involving shapes, spaces, and locations.
- Have children position their hands, feet, or bodies to make basic shapes.
- Offer containers of various shapes (cubes, pyramids, etc.) for sand and water play.
- Encourage children to work together on puzzles, tangrams, and mazes.
- Invite children to draw or make 3-D representations of things they observe indoors and outdoors.
- Let children explore drawing aids such as rulers, protractors, French curves, and stencils.
- Provide building blocks, pattern blocks, geoboards, pegboards, straws, buttons, and beads for creating designs and structures. Teach children to weave, braid, and sew. Show them how to fold, cut, and arrange paper and other materials to make mosaics, collages, and other designs.
Play games that involve spaces, shapes, and locations.
- Introduce table games such as Carrom, Candyland, tic-tac-toe, and card games such as Slapjack or Memory.
- Teach active games such as Fox and Geese, Mary Mack, Musical Chairs, beanbag toss, and variations on bowling.
