# All About Shapes - What is a Square?

Square is one of the first shapes kids learn to identify. Kids start to notice differences between shapes at around 18 months old, and then they gradually begin to understand, recognize and name basic shapes such as circle, triangle, square, and rectangle. Through kindergarten to 6th grade, kids will learn more and more about shapes and geometry.

A square is a regular quadrilateral, which means that it has four sides of the same length and four right angles or corners. This worksheet is all about squares. It aims to help kids learn to recognize squares. A square has four sides and four corners. All four sides are the same length, and all corners are vertical. Squares are everywhere. We can find square shapes easily around us; examples shown in this worksheet include a chessboard, a chocolate bar, a pedestrian crossing sign, dice, the flag of Switzerland, a wall clock, and a Rubik’s Cube. Squares can be big or little, and can be any color: green, blue, red, or purple. Once kids are comfortable with recognizing squares, you could ask them to do an easy but tricky exercise: count the number of different squares in a 2-by-2 and a 3-by-3 grid as shown in this worksheet. In general, this worksheet will be useful to help kids improve their geometry knowledge about squares.
