Today I have a little freebie for the older kiddos. This is a simple dice game for practicing adding fractions with like denominators and converting improper fractions to mixed numbers.
Now, hopefully you recognize that this game is very abstract. It is not a good game for introducing the concept of converting improper fractions to mixed numbers. It is a great game for practicing the concept once the kiddos understand it.So how do you introduce this concept at the concrete and representational stages? Well for concrete learning, fraction tiles are a great tool. You could make your own out of fraction strips, if you don't have the tiles. To model an improper fraction, you will need more than one set of tiles. Does that make sense? A tile kit will only have 4 fourths, so to model 6/4 you'll need to combine sets. It's important that when they use the tiles to model the improper fraction, they make groups based on the denominator. For example, to model 6/4 it would look like the drawn model in the next step, but you'd be using the tiles instead.
The next step is having kiddos draw models of improper fractions. Again, if they are thinking in terms of candy bars, it is oh so easy. For 6/4, their model would look like the one below. They know that each candy bar has 4 parts, so they draw the first candy bar. They shade all 4 pieces in that candy bar, because they ate them all. They know they kept eating, so they draw another candy bar. They shade 2 of those pieces, because now the model shows they ate 6 pieces. They can easily look at the model and see that they ate 1 2/4 or 1 1/2 candy bars. Magic!
How do these short little "I'll share a freebie" posts get so long? Ha ha. Anyway, here's the freebie! Enjoy!
