At the start of each school year parents and teachers alike go out and buy school supplies. Now it's your students turn. I have provided a basic supply listened sheet for work. You can use paper ads, but I used online sales. For my 6th graders, I limited their website options to 2, Staples or Walmart. Depending on the grade level, you may only give them 2 sites to find all the items, or leave it more open-ended and have them find the best deals out there. This helps students develop fluency with money and seeing how much money their items their parents buy each year can cost. I had them do it in partners, so one could check Staples and the other Walmart to compare prices easier.
My students love competitions, so I had a prize for the top 3 groups who had the lowest grand totals for their supplies.
