When does 4+4 = 8? When four sides plus four angles equals one quadrilateral! Become a shape detective by singing a song, playing an online game, and gluing toothpicks together to make quadrilaterals!
During this lesson, you will learn how to identify quadrilaterals by using clues! Read on to learn the clues that will help you detect which shapes are quadrilaterals and which shapes are not!
You are ready to start learning about quadrilaterals!
Continue reading to learn about shapes that are quadrilaterals.
Take a look at some of the shapes below.
On a plain sheet of paper, write down some of the things you notice about the shapes.
Write at least two or three sentences about the similarities and differences among the shapes.
Share your sentences with an adult.
