Drag the green circle to any number. Click the green flag and the cat will go to the green circle. Drag the red target circle to any number. Decide which repeat blocks you need to use. Each has either a +1, +10, -1, or -10 block inside the repeat. Combine the blocks and change the input in the repeat blocks to make the cat go from the green circle to the red circle when the space bar is pressed.
Ask students how they knew they had to stop counting by 1s or by 10s.
