Knowing number combinations that equal 10 is a basic skill that can help students understand more math facts. To help students memorize addition facts that equal 10, play a game of Find 10. Prepare several sets of cards numbered 0 to 10. Lay all of the cards face up in rows. Players look at the grid and pick up two cards that total 10. For example, a student could choose a 3 and a 7 card to equal 10. Play continues until all of the cards have been chosen. As students get more comfortable with combinations equaling 10, ask them to pick up three or more cards that will equal 10. For example, the 1, 4 and 5 cards would add up to 10.
Practice multiplication facts with another card game. Prepare several sets of cards numbered 1 to 10, or use a deck of playing cards and value the face cards as 10. Divide the deck between two players, each making a stack in front of him. Players turn over the top two cards from their stack and multiply the two numbers. The player with the higher product picks up all the cards. If the totals are the same, players put down two more cards and the person with the higher product collects all eight cards. Play continues for a pre-determined amount of time or until one player has collected all of the cards.
Use double-six dominoes to work on subtraction facts. Prepare several sets of cards labeled 0 to 6 and place them face down in a pile. Each player takes 10 dominoes and places them face up in front of him. On his turn, a player draws a card and then tries to find one of his dominoes that has a difference the same as his card, and discards it. For example, if a player drew a 4 card, he could find the domino with 6 and 2, because the difference between the numbers is 4. The game ends when one player has discarded all of his dominoes.
To practice any type of math fact, teachers can play bingo with students. Prepare bingo boards by making a grid filled with answers to math facts you want students to practice. Each player receives a board and several small markers to cover the spaces, such as small candies or crackers. The teacher calls out a math problem and students find the answer on their bingo boards and cover the space. This game can be used to practice addition, subtraction, multiplication or division facts, and teachers can adjust the bingo boards to match the level of problems that students are practicing.
