Flashcard Fun: For this activity you can make your own flashcards using blank index cards. On several cards make an addition sign (+). On other cards make the subtraction sign (-). You will also need to make flash cards with the equals sign (=). On other index cards you will need to make problems (both addition and subtraction) that do not contain the operation sign in the middle of the problem, but do include the answer. (ex: 3__ 1 = 4) Help your child to practice with the flashcards. The first level of this activity would be to just use the +, -, and = cards. Once your child is able to successfully identify the signs and what they mean, you may move to the next set of cards (missing the operational sign in the middle of the problem). For this portion of the activity, they can use a whiteboard to copy down the problem, and then attempt to work it out, so that they can identify which sign is missing.
