  • Talk about the day’s events and discuss what might happen tomorrow.

Number Sense Development

Milestones: By 36 months, most children:

  • Begin to use words like “more” and “bigger” to talk about amounts
  • Count a few numbers and build their understanding of quantity through activities like setting the table with plates and cups
  • Notice how you use counting in everyday life and start imitating you to learn about numbers
  • They usually learn to say “1-2-3-4-5” (sometimes putting the numbers in a different order) before knowing that each number represents something.
  • Count their broccoli pieces up to 3 or 4, but they might count the same piece twice or miss a piece. They are still learning the sequence of numbers and might miss a number, for example, “1-2-4.”
  • Hold up two fingers to show you how old they are, and they can hand you two tissues when you ask them to
  • Understand the terms “a little bit” and “a lot.” They can choose when you ask if they want a little yogurt or a lot.
  • Use their fingers for counting.

Skills to promote cognitive number development:

  • Talk about the shapes and sizes of bath toys, like “This is a round ball, and this is a long boat.” This helps with shape and size recognition.
  • Read books that involve counting and counting objects on each page together. For example, “Let’s count the stars on this page: one, two, three.”
  • Count the steps in your bedtime routine, like “One, brush your teeth. Two, put on pajamas. Three, read a story.” This helps them understand sequences and routines.
  • Use terms like “a little bit” and “a lot,” and let your child choose. Ask, “Do you want a little bit of yogurt or a lot?” This helps them understand quantity.
  • When pouring a drink, show them the full cup and say, “Your cup is full of juice.” After they finish drinking, show the empty cup and say, “Now your cup is empty.”
  • When giving your child food, say, “You have more carrots than I do,” or “I have less rice than you.”
  • During meal time, try, “How many grapes do you have? Let’s count them before we eat: 1, 2, 3.” Counting food items reinforces the concept of quantity and helps them understand that numbers represent actual objects.
  • While getting dressed for the day, try this, “How many socks do we need? Let’s count them: 1, 2.” Counting pairs of socks reinforces the concept of quantity and helps them understand that numbers represent actual objects.
