Step-by-step explanation:
Jackson can use the "Control" menu in Scratch to repeat an action a certain number of times. Specifically, he can use the "Repeat" block under the "Control" menu to execute a set of blocks a specified number of times. To repeat an action 10 times, he can drag the "Repeat" block onto the workspace and change the default value of 10 to the desired value of 10. Then he can place the set of blocks that he wants to repeat inside the "Repeat" block.
