Holiday candy sales – Which holidays are associated with candy? For which of those holidays do they think that the most candy is sold? What percents of annual candy sales do they think each holiday contributes?
Students reason and estimate with these questions. In Brian’s activity we ask students to translate a pie chart of information on candy sales to actual dollars spent for Halloween, Easter, Christmas and Hanuka, and Valentine’s Day. 6. RP.3, 7.EE.3, 7.RP.3, circle graph, data analysis, estimation, percent
Peeps – Students estimate the number of Peeps sold each Easter season. They consider reasonability by making guesses they think might be a little too high and a little too low.
Students determine necessary info, problem solve and improve their original estimates. They conduct random samplings of their estimates and compare the mean of their estimates to the actual number of peeps sold each season. The lesson includes a great old dancing Peeps video. 7.SP.1, 7.SP.2, MP1, MP2, MP3
Giant chocolate bunnies – What can you deduce about the bunnies (pictured in this activity) from the descriptions given … solid? hollow? cost per pound? cost per height? Anything else? data deductions and analysis, ratios, unit rate, 6.RP.A, 7.RP.A
