Understand common Year 1 common 2-d and 3-d shapes mistakes, why they happen and how to fix them with short practice checks.
These are common ways children can become stuck on this type of question. Use the short check after each one to make sure the correction is understood.
Why it happens: Shapes are classified by properties, not by how they are rotated or drawn.
Fix it: Check sides, angles, faces, edges or vertices before naming the shape.
Why it happens: An angle measures turn, not how long its arms are drawn.
Fix it: Compare the opening/turn and ignore the drawn length of the arms.
Why it happens: A reliable classification uses properties that every example of the shape has.
Fix it: Ask whether the statement stays true for every version of the shape.
