Last year, I had a bulletin board up outside my door with questions for each grade level. Since moving rooms, I don't have as much room outside my door so I was looking for some ideas on how I can engage students. I was thinking of doing some of these boards with questions. I love the idea of them proving me wrong -- that was the premise of what I did last year too. Have you used something like this before? Any suggestions or tips? (It probably goes without saying, but I will say it anyway, this is not my photo.)

With some of my second graders, we have been comparing numbers (two and three digit). I created these cards that I printed and laminated to help them. One of the trickiest things about comparing numbers is having students realize that whatever number comes first, that's what you're saying is greater than or less than the next number. We can't just find the largest number.
