You need to prepare number cards large enough to be seen by all the students. Each card will have a different odd or even number, of two-, three- or four- or five-digits. On the reverse side of the cards, write whether the number is odd or even. Show the students a number card. They will stand up or remain standing, for even numbers, and sit or remain seated, for odd numbers. It's easy to identify students that get the wrong answer, and they are out of the game. Depending on your class size, you may want to have the students go to the back of the room after they are out. Keep the pace brisk. The winner is the last student standing.
To play this game, you will need 100 blank index cards per group of four students, 20 blank index cards per group and eight blank index cards per students. Write different multiple-digit odd or even numbers on each of the sets of 100 index cards. Write either "+" or "-" on the 20 blank index cards. On each of the eight blank index cards, write one of the following rules: "If you add a number to itself, the answer is even." "If you add two odd numbers, the answer is even." "If you add two even numbers, the answer is even." "If you add an odd number and an even number, the answer is odd." "If you subtract an even number from an even number, the answer is even." "If you subtract an odd number from an odd number, the answer is even." "If you subtract an even number from an odd number, the answer is odd." "If you subtract an odd number from an even number, the answer is odd."
Divide the students into groups of four. Give each group one set of 100 index cards, face down on the table. Give each student a set of rules cards. The first player will draw two number cards from the deck, and one card from the operations deck, and lay them face up on the table. She will look through her rules cards and pick the one that applies to the number cards and operations card she picked. She will read the card aloud, and if she is correct, will keep the two number cards and put the operations card in the discard pile. Other players may challenge her answer. If they are correct, they keep her number cards. If she was correct, she gets a second turn. Continue to play clockwise around the table. Reshuffle the operations cards and turn them face down on the table when needed. The player with the most cards at the end of the game is the winner.
For this challenging skip counting game, you need 40 blank index cards. On 20 of the index cards, write various 1- and 2-digit even numbers. On the remaining 20 index cards, write various 1- and 2-digit odd numbers. Keep the cards separated into even and odd piles. Divide the class into teams. Write a 3- or 4-digit number on the blackboard for the first player on Team 1. That player will pick a card from either the even or odd number pile. She will count up 10 times from the number written on the board, in increments of the number on the card she picked. If she is successful, the team is awarded a point, and she goes to the back of her team's line. Play continues in this manner until every player has had at least one turn. The team with the highest number of points is the winner.
For this game, each student needs two different color pencils, and you will need to prepare a unique "Paint by Number" picture for each student that can be completed using two different colors to reveal a hidden word. Each portion of the picture to be colored with Color A should be numbered with a unique even number. The portions to be colored with Color B should be numbered with a unique odd number. When the students have finished their pages, they consult with each other to determine how to combine their words into a secret message. You can award a class prize, such as ice cream, or give them a "No Homework Night."
