If imitation is the purest form of flattery, then Graham should be pretty darned flattered. I imitated (read: stole) his The Big Pad problem for slightly younger grades. Graham’s task necessitates fractions, which was a bit further down the line for my intended audience, roughly grades two or three. In this task, the giant Post-It is 15 inches x 15 inches and the small Post-Its are 3 in x 3 in. Enjoy!

(Coming soon: a 8 in x 6 in Post-It Problem for grades 4-5, with additional commentary)

Act 1


  • Watch the video. What do you notice? What do you wonder?
  • How many small post-its will it take to fill up the big post-it?
  • What do you know? What do you need to know in order to solve the problem?

One thought on “Post-It Problem: Grades 2-3

  1. Right on Geoff! With the amount I’ve borrowed from you over the years, it only seems fitting that I was able to return the love. I just shared this with a whole bunch of grade 2 teachers. This task/context fits beautifully with 2.G.2. Cheers!
    Now you have a personal reason to fire up the 2 Grade Curriculum Map. Just sayin:-)
