Add math words like one, two, more, and all gone as you respond to what they say and do: During snack time, you might start out by saying, “It’s snack time, let’s get two crackers. One. Two.” Notice if your baby is reaching for the crackers, and comment on what they do: “You picked up one cracker! Now there is only one cracker left. Do you want more?"
Add math words like big, small, full, empty, and count from one to five. Respond to what they look at, do, and say: Your bowl is empty. Would you like more grapes? Let's count them, one, two, three grapes! This grape is big and this one is smaller."
