Reading Passage
Find the Triangles
Look at all the shapes! Can you find the triangles? A triangle has three sides. Count them: one, two, three. A triangle has three points too. One, two, three points!
See the square? A square has four sides. It is not a triangle. See the circle? A circle is round and has no sides. It is not a triangle.
A triangle can be big. A triangle can be small. The sides can be long. The sides can be short. But it always has three sides. Can you find the triangles now? Good job!
