Shape matching is about comparing a visible form with the place or outline that corresponds to it. The useful visual clues are the shape’s edges, corners, and orientation.
Compare the outlines
Look at one shape and the place it may fit. Notice whether the edges are straight or curved and where its corners point. Comparing one feature at a time can make a busy picture easier to read without turning the activity into a test.
Talk about position and direction
A shape can look different when it is turned, even though it is the same form. You might describe which side is at the top or compare the width of two edges. Let the child point, name, or simply look; there is no required vocabulary for exploring the picture.

Tangram pages show how several geometric forms can make a larger composition. Polyomino puzzles use connected pieces arranged in a layout. These guides describe their visible mechanics; the App Store listing is the place to check current availability.
