I taught K-5 math through special ed in a very busy resource room, but one year, during the last 45 minutes on Wednesdays, it was just the two ed techs and two girls- a 3rd grader and a 5th grader- who were cousins. We decided that instead of a math class, Wednesday afternoons would be "Ladies Uno Day." Uno sort-of qualifies as presenting math skills, and honestly, even if it doesn't, it was a good way to end a day in the middle of the week. I saw the 5th grader recently- she's 21 or 22 now. She remembered me, and asked if I remembered our Uno games with her cousin and the other ed tech! <3
