Putting information to music makes it easier to remember. Sing your "one plus one equals two" type addition facts to a familiar tune such as “Old MacDonald Had a Farm” or “Twinkle, Twinkle, Little Star.” Make up your own lyrics or use songs written specifically for memorizing addition facts. Load the song into your MP3 player and listen to it as you sleep or sing it on the way to school. Get a group of friends together and become stars in your own music video as you each take lead parts in the song or rap it out together.
Games offer a fun way to learn dry facts. Write each addition fact, such as "two plus three equals five," on two cards. Shuffle the cards together and lay them face down. Turn over the cards until you find a match to a previous card and match the two cards. As you pick up your matched cards, say the addition fact aloud. Another fun game for math fact memorization uses competition and flash cards. Have someone quickly flash a card with an addition problem pictured. Blurt out the fact as quickly as possible to win points for the knowledge. Keep score and compete against your friends and classmates.
Learn with your body in motion doing something you like to do. For example, rehearse your addition facts as you jump on a trampoline, hula hoop, play hopscotch or swirl colorful streamers around you. Say the facts aloud as you move. Count by twos or threes to practice your "two plus" facts as you jump rope. Vary your activities for fun. Post the addition facts on the wall where you can see them as your move or on the grid where you hopscotch.
Use math manipulatives to bear out the truth of your addition facts. Add two cookies and two cookies to make four cookies or stack four blocks with three blocks to make seven blocks. Make up stories as you use the manipulatives. For example, tell yourself that you have four lemons and your friend has two lemons, so you put them together to make six lemons for use in your lemonade stand. Count beans, matchsticks, pebbles, acrylic gems or whatever items come easily to hand.
Reward yourself when you get all the answers right. Learn addition problems in related groups, called chunking, so you learn all the “two plus” facts together. Choose rewards that mean something to you such as earning five minutes of gaming time for every 10 facts correctly memorized.
