Talk about shapes as a group. Introduce the basic circle, triangle, square and rectangle.
Learn in depth about each shape at a rate of one per day or week. Explain how a circle has no sides or corners; a triangle has three sides and three corners; a square has four sides and four corners that are all the same and a rectangle has two pairs of sides that are the same and four corners.
Have students draw various shapes, using a template or freehand. Ask them to identify each shape verbally. Checking their work will ensure that they are able to form and identify each shape.
Take students on a shape hunt around the school or neighborhood. Create a simple tally mark chart so students can keep track of how many of each shape they can find.
Review shapes routinely so students retain their new knowledge. Shape identification can easily be added to math routines or free choice times using pattern blocks or Playdoh.
