•  Divisibility  Play this game alone or with a partner to test your divisibility skills. http://www.mathfox.com/learn/divisibility-volley-pirate-classroom-game-for-4th-grade-children/ Test each number for all rules of divisibility Find which numbers are divisible by the numbers two through eleven Prime or Composite  Go to this website to test your knowledge of prime and composite:   Prime Numbers Rap song:   Play this card game with a friend: Shuffle the cards and deal them face down to the players in a pile. Each round consists of all the players turning over the first card in their pack in an outward motion, giving every player a fair chance of seeing the card as it's turned over. When a prime is played, the first player to call out "prime" takes the card and any others that may be in the stack. If there's a tie, the pile should remain in the center and play should continue. If the number turned over isn't a prime number, leave the cards in the center of the table until a prime number appears and the cards are won. After a player wins cards, they must shuffle them into their deck before the game can continue. Play until one player has all the cards or set a time limit on the game and stop when time is up. The player with the most cards at the end of the game wins.

For example, you might choose numbers such as 8 (which has the factors 2 and 4) or 9 (which has 3 as a factor) more often than 7 or 11, which are both prime. Most of the numbers should be between 1 and 20, with a few larger ones that have a lot of factors (e.g., 20, 24, 30). Divide the pile of index cards in half into two smaller piles, and give each player one of these smaller piles. Both players call out “1, 2, 3…war!” and simultaneously turn over the top card in their piles and place it between them. The goal: as quickly as each player can, calculate the lowest common multiple of the numbers on the two cards, and call it out. The first player to call out the correct lowest common multiple wins the round and gets to add both of the cards to the bottom of her pile. Repeat Steps 3 and 4 for the next round. The game ends when one player runs out of cards. The other player is the winner.
