This letter recognition sensory bin activity is super simple to set up and your preschooler will love it.  It will have them working on their fine motor skills, problem-solving skills, and letter recognition!
I’m not sure if I have shared this with you but I LIVE off of coffee! It is my fuel! With that said, today’s sensory bin activity had me in pure heaven because my house smelled like a coffeehouse!
I will warn you though, it can get messy so you may want to take it outside or to an area of the house that is easily vacuumed/swept!

Step #1
Pour coffee grounds in a sensory bin.
Step #2
Use a sharpie to write this month’s focus letters on the rocks. (One letter per rock)
I also included some of the letters we learned from previous months to review.
Step #3
Invite your preschooler to use their dump trucks and diggers to drive in and dig the coffee and rocks. Let them engage in free play for a while and then encourage them to work on letter recognition by finding various rocks. You can say things like, “Our construction crew needs the rock with a D on it. Can you use the truck to bring the letter D over here?”
