Watch with Miss Tomat:
In your gridbooks, write a maths vocabulary list titled, The Cartesian Plane. When you have finished, you can define your words. Eg,
A coordinate plane is an important tool for working with these equations. It is formed by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis. The two axes intersect at a point called the origin.
Consider this…the ORIGIN can be thought of as the centre of the soccer field where the ball is placed at the start of the game.
