PRODUCT DESCRIPTION

This is a double set of task cards designed to support Common Core 5.NF.B.4, which is multiplying mixed numbers using the area model. There are 28 task cards in 2 separate decks (total of 56 cards). They use the identical models, but are labeled differently to meet the needs of different students. All of the models include fractional dimensions for both the length and width, and all use only unit fractions.

I designed these to use with my above level fifth grade students. They were having trouble multiplying fractions and I was preparing to move into volume (with fractional dimensions). I wanted them to be able to see the pieces that are formed. I also wanted to be able to teach multiplying mixed numbers without resorting to a rote method of using improper fractions and cross-canceling. This allowed the kids to see each term in the equation being multiplied by the others using the distributive property.

Some of my students couldn't even identify the models at first, so I created a version of these cards (Set B2) that only labels the fractional dimensions. I also included a version of the answer sheet that only requires them to record the dimensions. The alternate version of the cards gives the students the dimensions (Set B). My students found the B2 set significantly more difficult, but I felt it better prepared them for the grade 6 volume standard.

I color coded the edges of the quadrilaterals because some of my students were not understanding what happened when the dimensions included unlike denominators. They had a tough time identifying which side had which fractional piece, which led to the majority of the inaccuracies in their early practice.

These cards are designed to be used after the SET A cards (available in a separate listing, or in a bundle in my store). Set A cards use only one fractional dimension. Set B uses both fractional dimensions. All sets use only unit fractions. (My plan is to make a set C with non-unit fractions-- we'll see how much I get done over summer break!).

This is a 25-page PDF file. It includes the 28 task cards for SET B, the 28 task cards for SET B2 (same problems, less labeling), 3 options for recording sheets, and an answer key for the cards. It also includes a student worksheet, also presented in both formats to mirror the cards, and the answer key. I also created 2 note pages for the students that show the model with like and unlike denominators and compare each to the distributive method of multiplying. There is also a note sheet from me about how I used the cards. They are in color, but will all work well printed in black and white.
