Quadrilaterals

Not all things with four sides and 90 degree angles are squares or rectangles! Sometimes the angles in these 4-sided shapes are less than (or greater than) 90 degrees, causing them to have a slightly odd shape. These are called quadrilaterals and come in a few different varieties. In this tutorial, you'll learn about them. Common Core Standards: 5.G.B.3, 5.G.B.4

Coordinate_plane_word_problems

Represent real world problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

Intro_to_the_coordinate_plane_

How can we communicate exactly where something is in two dimensions? In this tutorial, we cover the basics of the coordinate plane and graphing points.
