Dar Forma a Nuestro Mundo: Level 3 (Mathematics Readers)

Shapes are everywhere you look. They are in the streets, in your classroom, and in your home. Two-dimensional (2-D) shapes have length and width. Regular 2-D shapes have angles (which are measured in degrees) that are all equal, and irregular shapes have angles that are not equal. Shapes can create different patterns. You can discover the different types of 2-D shapes and patterns as you look around you.
