2D Shapes

Shape Matcher—Identical Orientations & Sizes

Sub Trajectory: Comparing

Identical: Matches familiar shapes (circle, square, typical triangle) that have the same size and orientation. In specific congruence tasks, may think that two shapes are the same if they are more visually similar than different.

Orientations: Matches familiar shapes with different orientations.

Sizes: Matches familiar shapes with different sizes.

When working on specific congruence tasks, children at this level may think that two shapes are the same if they are more visually similar than different. Or, they may think that two shapes are the same after matching one side on each.

Experiences in many contexts encourage children to match shapes in context with a lot of perceptual support. Play shapes, shape puzzle boxes, and even picture books can be helpful. Discussion can emphasize that "These are exactly the same shape" and adults can encourage children to "show the match" by putting one shape on top of the other.
