All About Shapes - What is an Octagon?


Shapes are all around us and they are one of the first mathematical subjects kids love to learn about. Kids start to notice differences between shapes at around 18 months old. At 2 years old, they begin to understand, recognize and name basic shapes of circle, triangle, square, and rectangle. At 3 years old, kids start to move onto some harder shapes such as star, heart, oval, and diamond. Once they have a good understanding of these shapes, it is time for them to learn about pentagon, hexagon, and octagon. An octagon is a polygon with 8 straight sides and 8 corners.

This worksheet is all about octagons. It helps kids learn to recognize octagons. An octagon is a 2D shape that has 8 sides and 8 corners. Octagons can be any size, as long as the eight sides/edges all connect to make a closed shape. Octagons can be any color: yellow, green, red, blue, and so on. Some popular examples of octagon shapes around us include: stop signs, Chinese Feng Shui Bagua maps, octagonal plates, octagonal windows, and umbrellas. You can easily get an octagon shape by cutting straightly the 4 corners of a square or a rectangle. An exercise is given at the end for kids to distinguish octagons from other similar but different shapes. This could help kids reinforce the concept of the octagon shape.
