The Ready Steady Code grids in the Scratch backdrops library add about 80% more functionality to SCRATCH for integration in school. The grids shorten and simplify the code for Maths lessons. They can also facilitate the layout and design of SCRATCH projects. Here is an easy way to test coordinates.
The X and Y coordinates in this test refer to squares on the Ready Steady Code XY-grid-30px RSC grids. Remember X is forwards + and back - (horizontal) and Y is up + and down - (vertical). A flashing green apple indicates CORRECT. Seamus O'Neill © 2019
