I always found plenty of learning opportunities around grocery shopping and I loved getting both my kids involved in the entire process from menu planning.
Price a collection of play food or items from your pantry, and let your child bargain his way to a better understanding of math, and frugal spending habits.
WHAT YOU DO:
Before you get your young learner involved, use the labels or masking tape to price the food items.
Once you have priced the food, arrange it on your table or counter and invite your child to shop.
