Take plastic easter eggs and put small candy inside. Write problems of any kind of math on a scrap piece of paper, and write the answers on the eggs. If there are any eggs left over put down any OTHER numbers that are NOT answers. Go hide ALL of the eggs. Tell the child to find them and mention to the child that there is a surprise in the egg for them if they get it right. Before the kid eats the candy they have to show you the answer to check it right. You can use this idea at any time of the year.
