Flash & Fact:  Solve each problem.  Check your answer on the back.  Stack the “practice needed” cards in one pile, and use then to play the games below.

Fact Family Fun:  Sort your practice-needed cards into fact families-cards with one common addend.  With the answer side up, find a pattern to the problems and answers.

Mind Math: Shuffle the deck and choose three cards.  Lay the cards answer side down in the order of their sums. Turn over the cards to check your answers.  For a challenge, use five or more cards.  For a brain stretch, mix addition and subtraction cards.
