Talk to your child about what you are planning to buy at the market and explain that you need help locating items. When you are at the aisle where an item is located, hand your child the coupon and ask her to find the item. When it’s found, ask how she knew it was the right item (Has the picture of the fish on it, matched letters, recognized the name, etc.).
Keep children in your sight at all times. Talk about the areas of the store different items might be found. (Classification).
