These worksheets go with the OREO stacking project, as described on www.projectsbyjen.com website. Students see how many OREOs they can stack before they topple. This 3 piece set includes a page for students to use their highest number and make it several ways (best for 1-3rd grade), a challenge page (challenge someone in your class or online, through the project), and a pictograph page to make a pictograph of your results as well as someone else's results. See the website for additional ways to incorporate art and other subjects into this project. The pictograph could be used for any grade level. The challenge page includes an average, so probably 2nd and up. OREO is a registered trademark.
