Instructional Ideas
  • Have the class record the name and definition of each shape on the back of the cards, using them as geometry flash cards
  • Create sets of words cards with the names of each shape and use them with the picture cards to play a matching game
  • Have students cut out and sort the shapes into categories based on the number of sides and types of angles they have
Classroom Considerations
  • Note that this resource only includes the shape cards, requiring the teacher to come up with directions for how they are to be used
  • Laminate these cards, allowing them to be used year after year during geometry lessons
  • A total of 18 different shape cards are included in the set
  • Shapes are shown in different orientations to challenge children's understanding of geometry
  • Three different types of triangles are included: right, acute, and obtuse
  • In two of the pictures, the sides of the shapes do not meet neatly in the corners, but this does not affect the ability of children to identify the shapes
