Scratch coordinate system

Coordinate Grid

Do you know everything about Coordinate Grids? Let's find out!

Practice!

Now, let's put what you know to the test!

Good results or not, always remember:

• X comes first! Always start going from left to right. Left means negative, right means positive!

• Y comes second! Continue from where you stopped on the x-axis. Either go up for a positive number or down for a negative number!

• You are amazing! Let's keep practicing!
