Small, Medium, Big

Small, medium, and large wooden blocks for playtime at day care

This activity promotes development and learning by encouraging children to demonstrate an understanding of size, spatial sense, and classifying and sorting. As children observe and notice differences in size, they gain early math skills.

Materials Needed:

  • Three objects that come in small, medium, and big sizes, such as three shoes, three bowls, or three toys

Participants: This activity is intended for adult/child interaction.


  1. Show your child the three items and label them or ask your verbal toddler to name them.
  2. In a small voice ask, “Which one is little?” Help your child point to the smallest item.
  3. In a louder voice, ask, “Which one is bigger?” Once again, encourage your child to point to the correct one, offering help if needed.
  4. In an even louder voice, ask, “Which one is the very biggest?” Again point to the biggest one. If your child is interested, try moving the items and play again.
