When Math Happens 
How did you create the treasure hunt that had one question at a time and then a video if they got it wrong?
Thanks for the comment! I followed something similar to this from Alice Keeler. Takes some time, but it’s pretty neat.
What is Spiraling Practice, and how do you use it? Thanks!
Thanks for the question! Spiraling Practice is just a practice handout with concepts that we’ve already learned during the year. The goal is to keep students fresh with previous concepts while we move on to new concepts. In addition, I use spiraling to work on common errors I found in previous units. I also like to use spiraling to help prepare students for retakes and upcoming district exams.
Usually, spiraling assignments are done either during independent work time or free group time toward the end of class. I usually don’t teach through the handouts unless questions arise while students are working on them.
Hope that helps!
