This is a bundle of my 2 sets of task cards designed to support 5.NF.B.4.B, multiplying mixed numbers using the area model. Each set is available separately in my store, but this is the bundle of both SET A (one dimension is fractional) and SET B (both dimensions are fractional). All of the cards in this set use unit fractions for the fractional values.
I designed these cards to use with my above level fifth graders as we transitioned into the common core. I was working to build towards finding volume with fractional dimensions (in core 6), and realized that they had many gaps in their ability to use the area model with fractions. In fact, they had a really hard time even identifying the multiplication expression that an area model represented. To try to address all of these weaknesses with these cards, I created duplicate versions of each set of task cards.
In Set A, there are 2 sets of 28 cards. Each rectangle has one whole number dimension, and one fractional dimension. Each corresponding card has the same quadrilateral with the same dimensions. In one version, the students have to identify the dimensions. In the other easier version, the dimensions are listed. My students really needed the practice in identifying the dimensions, then we used the model to find the product. I had them use the distributive method of multiplying because I wanted them to see the correlation between the areas of the shape and the multiplication.
In Set B, there are also 2 sets of 28 cards. Each card has a quadrilateral (either square or rectangle) that has BOTH dimensions including fractions. This increases the difficulty level of the model substantially for the students. They need to track each fractional side of the shape, as well as the overlap of the two sides. Some of the shapes have fractions of like denominators (which are easier), and some include unlike denominators.
Each set of cards also includes recording sheets (several options), an independent student worksheet, all answer keys needed, and note pages for student notebooks.
This is a 46-page PDF. The first 21 pages are the SET A cards, and the last 25 pages are the SET B cards with two fractional dimensions.
