Hands on Learning
Try some of these games to practice at home. For example, make a "football" out of paper which is usually shaped like a triangle and practice flipping it with your finger between the fingers of someone else. His or her fingers represent the goal. The person making the goal would hold his or her hands up palm facing your fingers folded down except for his or her index finger which points up or vertical and his or her thumbs touching horizontally. Record how many times you make the goal versus how many times you don't after trying 20 times and you have a ratio of hits to misses. Let the other person do the same. Determine who had the best ratio of hits to misses. Remember to reduce your numbers. You can make all types of variations to this game including making "baskets" into any object that would represent a basket and some kind of ball or using a real basketball and basketball net.
You may also create a matching game. Have someone write out equivalent ratios on index cards in fraction form then you would have to match each equivalent ratio. For example, 2/3 is equivalent to 6/9 because 6/9 is reduced to 2/3 by dividing 3 into 6 and then 3 into 9.
You can also practice ratios by working with recipes. Pick a recipe for your favorite food and practice changing the amount of each ingredient based on the number of people you plan to feed. For example, if a recipe requires 2 cups of sugar and prepares enough for 4 people the ratio is 2 to 4. If you want to make enough for 8 people, then double the sugar to 4 cups. Your 2/4 ratio is now a 4/8 ratio.
Use money to create ratios. For example, determine the ratio of pennies to a dime or nickels to a quarter or dimes to dollar. Then reduce all the ratios you come up with and determine if any are equivalent.
Finally, create a dice game which you can play by yourself or with others. Write down the following ratios on a sheet of paper for each player: 1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 2/1, 2/3, 2/5, 3/1, 3/2, 3/4, 3/5, 4/1, 4/3, 4/5, 5/1, 5/2, 5/3, 5/4, 5/6, 6/1 and 6/5. Then each player rolls the dice twice and marks off each ratio as they are rolled. However, there are other combinations than the ones listed but they are reducible to the ones listed. Therefore, if you role 4/6, that reduces to 2/3 which means you can mark off 2/3. Whoever marks off all the ratios first is the winner. Don't tell your opponents if they missed a reducible number!
