Q-Tip Letter Painting (Preschool, Kindergarten Activity)--great for teaching pencil grip, fine motor skill practice & letter formation. Makes writing letters more than just practice--make it an art project!
Ziploc bags with tempera paint. We practiced color mixing, fine motor skills, sensory exploration, and letter writing. It felt like getting messy. without the mess! Again, just a picture no link but so worth sharing this GREAT idea.
I think you could also have multiple pipe cleaners coming from one number and students have to show multiple ways to add numbers to get to that number. Counting with pipe cleaners and beads. Great for fine motor development too.
Free printable masks: to create the masks, simply print on card stock and laminate. Cut around the outside of the head, cut the eye holes (I use a box cutter), poke one hole near each ear and thread a piece of string or elastic through to create a mask.
