This is a 10-page PDF file that provides practice in solving problems with percents, including those where students must find the part (given the percent) or the whole, given a part. Each situation is scaffolded with a partially completed bar model/tape diagram that helps students visualize the quantities in the problem. All of the answers are whole numbers, with some problems requiring more challenging reasoning than others.
These cards were designed to directly align with Common Core 6.RP.A.3c using one of the recommended visual models. The tape diagram includes a number line to represent the percent portion and tape sections to represent the parts/whole. I have also included a worksheet for follow-up or homework, that includes the model without the values assigned.
The 24 task cards (4 per page) are 6 pages of the file, there is a 1-page recording sheet and 1-page answer key for the cards. The final 2 pages are the worksheet and the answer key for the worksheet.
I frequently use task cards with my math class, and will often run many sets of the cards and have the kids work in partners to solve the situations. I change the settings in my printer window to let me print the cards smaller than 4 per page to save on paper.
This approach allows me to walk around and meet with kids to find out where their level of understanding is. It also allows students to work at varying paces. I have found that my students really enjoy completing the tasks and it gets them talking about the math in a way that I was hoping they would. Other teachers have used these for centers and kept one master set available for extra time activities.
One big benefit that I realized last year was that when students were absent, it was very easy to send home what they missed. I could just give them a set of the cards and a recording sheet.
