Comparing corners worksheets

Two shapes in a row and one question: which has more corners? These free printable worksheets ask a child to count both and compare, which is a step past naming either of them.

What's on this sheet

Counting one shape's corners is not comparing two, and the difference is the whole exercise. A child who can say a pentagon has five corners has analyzed it; putting a pentagon beside a hexagon and asking which has more is what turns that into a comparison.

Why this sheet works

“The same” is one of the three answers and it is not a trick. Six of the ten shapes on these sheets have four corners, so a rhombus against a rectangle genuinely ties — and noticing that two shapes which look nothing alike have the same number of corners is the most useful thing on the page.
