My kids love pirate play and we have lots of fun with sensory bins so I put together a fun and super easy alphabet learning bin.
Large container of oatmeal($2.00 @ Wal-Mart)
Instant coffee($1.00 @ Dollar Tree)
Magnet letters($1.00 @ Dollar Tree)
Rest of the things were from around the house
Also the sensory bin we use is from Home Depot is a cement mixing container $5.00.
After the kids play with the coffee oatmeal mix can be placed in a baggie and reuse it. Can get multiple uses out of this for less than $5.00.
