Hi, I'm Luna from DoodleBeez. Shapes are all around us. A clock, a pizza slice, a window, a door. Today we will learn to name four shapes by counting their sides and corners.
Sides are the straight lines on a shape. Corners are where two sides meet. Let's count them on every shape we see. Counting sides and corners is the secret to naming shapes.
A circle is round. It has no straight sides and no corners at all. It goes round and round. A wheel, a coin and a cookie are all shaped like circles.
A triangle has three straight sides and three corners. Tri means three. A slice of pizza and a yield sign look like triangles. A triangle can be tall, short or tipped, and it is still a triangle.
A square has four straight sides and four corners. All four sides are the same length. A cracker and a window pane are often square. Count with me. One, two, three, four sides.
A rectangle also has four sides and four corners. But two sides are long and two sides are short. A door, a book and a dollar bill are shaped like rectangles.
Now it's your turn. This shape has three sides and three corners. What is its name? Pause and try. It is a triangle! Three sides and three corners always make a triangle.
Great job! A circle has no corners, a triangle has three sides, and squares and rectangles have four. Count sides and corners to name a shape. Practice naming shapes in the Math Lab at doodlebeez.com. See you next time!
