This is a double set bundle of task cards (2 sets of 24 cards each) that give students practice using a tape diagram/bar model to solve percent problems. In some problems, they are finding the part, and in others the whole. All problems use whole numbers for solutions.
I created my first set of cards with this model and used them with my above level fifth grade students this past school year. I hadn't used this model prior to my school adopting the common core, but I have to say that I was quite impressed with the way it helped the students. I was a bit surprised by how quickly it helped them visualize the whole and the parts. I had kids who quickly learned to draw their own model when they were solving problems, and they found some clever shortcuts. I knew that I needed to make more problems for them to work through, but just didn't get the time until the school year ended.
Now I'm ready because I have created 2 more complete sets of cards, both included in this bundle. These are different cards from my initial set (which is still available in my store). I realized as I worked with the kids this past year that some kids were ready to have the model presented without the numbers pre-filled. They had to then identify the part or the whole themselves. For the new sets in this bundle, I have included a duplicate set of each deck with the model intentionally left blank, as I think it will help differentiate within a classroom.
This is a 30-page PDF file. It includes 48 new problems (2 sets of 24 cards), and then the same 48 problems presented with the blank model (2 more sets of 24). It also includes an answer sheet for each set, an answer key, and 2 note sheets for students with directions for how to use the model itself.
The task cards are created 4 per page. The Set B and Set C cards are 6 pages long each. The duplicate sets with the blank model are an additional 6 pages each. There are 2 pages of recording sheets, 2 pages with the answer keys, and then 2 note sheets for students.
