So, I grabbed a colorful packet of Post-it Recycled Super Sticky Notes (more of the back side is sticky, so better for clinging to surfaces and not flapping up) and stuck them on a blank wall that the boys could reach. They were immediately intrigued and came over to pull them off and stick them back on the wall. I put a few that were a little out of reach so they would jump and stretch to get them too, which they did.
Perfect for inside fun!
My boys are just 19m, but during their pre-school years I plan to do something similar and try this Post-it Notes DIY Matching Game idea and Colored Masking Tape Hop Scotch board.
