I ditto what most have suggested and can add: Keva plank building challenges, scavenger hunts, monthly trivia, garden club activities planting/painting pots, stained glass activity, painting pumpkins, stress relief and fidget objects, if you have the floor for it a slime making activity, Mandala, checkers, we have a student voice board for students to contribute their thoughts on topics, interactive bulletin board displays, Sudoku-crossword-word search and other various puzzle sheets, I haven't done it in a long time and it is a lot of work but a Breakout edu/Escape room challenge, button maker activity, origami, tongue depressor/popsicle stick building challenge, and I have students assist with decorating and creating various displays. Something I want to do with the Environmental Club and leave out this year is a sewing station - button repair, patches, etc... (a lot of companies: Levi's, Uniqlo, etc... are tapping into the environmental upside and money saving benefits of garment repair). I actually found students were interested in hand sewing last year when the boys were coming into the library looking for a needle and thread to repair their Hacky Sack balls.
