What are some ways you spiral review throughout the year for students in math so that concepts stay fresh, and also students remained engaged?

I want to have some options for teachers as I coach them. I’ve done daily 3-5 questions review at the start of a lesson and I’ve added a review station to my station rotation. Just looking for other ideas!

What are some fun math brain teasers that get kids thinking before the math block officially starts? I found one like this and loved it but I'm looking for some other ideas!

We have some high school athletes that come every Friday to open up car doors for car riders and then come play math games with our 1st and 3rd graders. Our focus this year is going to be on fluency. What are some easy to understand and play fluency games that you like to do with your students?

I love this site that goes along with the book Math Fact Fluency by Jennifer Bay-Williams and Gina Kling: https://kcm.nku.edu/mathfactfluency/. There are great games with PDFs here.

I was looking for things for some new teachers for math talk and I came across this list. Are there any you would add or change?

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.)
