This activity will give kids practice making sense out of working with rational numbers and help kids overcome their fear of rational numbers, especially fractions. They will convert between rational numbers, find parts of wholes, and find percents of a number in a fun and meaningful way.
Cut out each set of cards, keeping them in the sequential order you see them in on the sheet. You may want to number the back of the cards 1- ? to keep them in order per set. Baggie each set of cards.
An option would be to make them into transparency pieces. This will help all students be able to watch each game played via the overhead, or you can place cards under the Elmo as you play.
Start with asking two students to compete in a game of make it ~ take it. Place the whole number card ie. 25 on the overhead along with 25 M&M’s. Determine who will go first, then turn over the rational cards one at a time. If the first card says 20%, the first player has to find (make) 20% of the 25 M&M’s, if they can make it ~ they take it! If not pass to the other player. 20% of 25 is 5, so now the next player has to find the next amount stated on the next rational card out of the 20 M&M’s that are left. They will keep rotating turns until all M&M’s are gone.
Alternate idea ……. ongoing class competition between the boys and the girls. Use cm cubes for the make it ~ take it game. As the girls or boys win cubes, have them contribute their make it ~ take it winnings to each of their class jars. Whichever team fills their jar up first wins! (You can determine what they win.)
You can keep this up all year with monthly competitions.
Watch the change in their abilities to work with rational numbers!
