I have taught fifth grade for five years, and adding and subtracting fractions with unlike denominators takes up a chunk of math classes during the year. We go over and over how to add and subtract these fractions, and the students need a lot of practice in order to master this skill! I try to mix things up in the classroom so that I reach my students in a variety of ways to help them learn this concept. I also know that while fifth graders like to think, they are big kids, I know that they still like games and "gimmicks" when it comes to learning too. I made this game to provide my students with practice in a fun "game format" for them. I tell them they are going to be "eating" brownies and they have to figure out how much they eat each time. By giving them "fraction brownies" and a cookie sheet to serve them on, my students get the silly fun while creating their own fraction problems. Basically, they are getting worksheet practice, creating their own problems which they find fun, and they get to use cookie sheets and "brownies" to add a little silliness to mix things up in the math classroom. I love it when my students can have fun and learn at the same time. Activities like this also allow me to focus on my struggling learners while my independent learners can have fun at the same time! There are seven color-coded sets of cards for this game so it is easy to keep track of which card belongs in which set. Just print, laminate, copy the worksheet, and you are ready for your students to have fun. Cookie sheets are optional, but my students think they are fun - you can buy them cheaply at a dollar store or a garage sale!. Enjoy!
