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.

A new (to me anyway!) site that I recently learned about is Youcubed! I have linked specifically the tasks section of this website because there are so many great ideas here for engaging students in real world math experiences. It appears to be for K through 12th grade, which is awesome! (https://www.youcubed.org/tasks/)

Any other amazing math task websites I need to check out that maybe I haven't?

One of my favorite ways to engage students in critical thinking and error analysis is by doing an activity called "Agree or Disagree with Mrs. T." In these activity, I will give students a word problem and then I will solve it (usually wrong with the most common mistakes students make when solving that type of problem). Students have to read the problem, think about how they would solve it, and then look at how I solved it to decide whether they agree or disagree and why. Usually I'm wrong, BUT I have to be right sometimes or they'll just assume I'm wrong and disregard what I did. I have attached a sample so you can see their reflection piece. What are ways you help students catch mistakes?
