good snowball rhyme too (can make a song- use tune I had a little dreiedel) Snowball Kindergarten Games - this is a fun winter game and to help kids practice oral motor exercises (toddler, preschool too)
DIY Sand and Rock Box by FSPDT. Gdjk -> made this with toilet rolls (aka tunnels) and moon sand instead of play sand. My son loved playing with it. The moon sand cleans up nicely indoors but play sand will be easier to play with when using the small cars.
