There are two versions of the dividing fractions game–I had half of my group working on one while they other half worked on the other. Check it out for more FREE math game ideas from numerous teacher bloggers! I’m linking up with the fabulous Laura Candler and her Math Game Round-Up. The second day, we worked on some dividing fractions games. (For instance, a student comes and asks me why they got an answer wrong, and it’s easy to say, “what step did you forget?” Problem solves 99% of the time.) We have already referenced it several times. They copied this in their math journal as well. You can see that we included the directions for dividing fractions by fractions, dividing whole numbers by fractions, and dividing fractions by whole numbers.Īt the bottom, we noted the “Keep-Change-Flip” shortcut. We introduced reciprocals first using our Funny & Fabulous Fraction Stories book, and then we did a step-by-step dividing fractions anchor chart. I don’t really emphasize the visual models, but I think it helps them to see why dividing a whole number by a fraction gives them a larger number and vice-versa. Thank goodness! You can see the math journal page I created with them in this picture.
But my kids rocked this! It clicked for them right away. He (like most of us) is old-fashioned, and we don’t feel the need to understand the “why” behind most of these math concepts. Funny story– I spent HOURS making a pretty study guide for this, and my sweet husband just didn’t understand it. We started with a math journal entry about dividing fractions with visual models.
And we tossed in mixed numbers while they were at it.

We tackled dividing fractions this week! I was a little bit apprehensive about it since these are wee little fourth graders working on this tough stuff, but they did GREAT! Although I follow the CCSS, I thought it was a little silly that they don’t include dividing a fraction by a fraction at fifth grade since it’s easy enough to add in once they know how to divide a whole number by a fraction and a fraction by a whole number, so we just did it all.
