Fractions in Kindergarten
I spent the most wonderful hour with Mrs. Streetman’s Kindergarten friends this afternoon. During that time, we read a book called Eating Fractions. This is a book I have read to KG students for years because it shows fractions in a real life application–food and recipes–that has real meaning to a KG student. While we read the story, we discussed that fractions are part of a whole, that we can have halves, thirds, and fourths and we were able to see real examples of each of these fractions. Following the story, Mrs. Streetman provided her students with a problem to solve and I am so excited by the outcome of this lesson! Her students were given 12 paper cookies and a workmat. The problem she posed to her students was this: You have 12 cookies. You want to share them with a friend. How many cookies will each friend get if you both have the same amount of cookies? The students set to work to figure this out with no other directions. As they worked, we watched. Some went right to two groups of six, some kids made two piles putting one cookie in one pile and one in the other, back and forth, until all cookies were divided, some even put five each in two groups and then split the remaining two. It was fascinating to watch. At the end, when all students were done, they has a chance to share their strategy and I loved hearing the explanations. I even heard, “Me, too!” from a couple of kids, proving that they were truly listening to their classmates as they shared. After this first problem, Mrs. Streetman posed a similar problem: instead of one friend, now you need to share your cookies with three friends. Again, they worked while we watched and again they shared when they were done. One student divided up his cookies into three groups and then had to figure out how to move some so that he had four groups. I was truly so excited to see these students thinking, manipulating and problem solving. It was awesome!
After the lesson was over, Mrs. Streetman and I chatted for a minute about the success of this lesson. We tend to think in terms of the mathematical process standards, as that was the focus of the Kindergarten Math Plan for 2011-2012, so we quickly went through the standards in our heads: Problem solving? Yes. These kids were solving a real-life problem. Communication? Absolutely. Their communication was spectacular as they stated their solutions to the problem. In communicating, they were also reasoning and proving their thoughts and ideas (which is another standard). We had a connection to real life in the problem and in the book that we read and the children represented their fractions on their workmats with symbols and with manipulatives. When we realized that this lesson hit all five process standards and hit them well, Mrs. Streetman was so excited that she did a happy dance in the classroom as the children packed up (seriously…she did…anyone who knows her will believe it!).
What a wonderful lesson from start to finish. I have already filed it away in my math binder to use next year when I head away from my TR position and into my Kindergarten classroom. I can’t wait to teach this lesson again. Well done, Mrs. Streetman!
