Unifix Counting Towers

Early Years (Age 3 – 6)

Curriculum Goal

Kindergarten: Demonstrating Literacy and Mathematics Behvaiour 

  • Demonstrate an understanding of numbers, using concrete materials to explore and investigate counting, quantity, and number relationships (#15).
  • Apply the mathematical processes to support the development of mathematical thinking, to demonstrate understanding, and to communicate thinking and learning in mathematics, while engaged in play-based learning and in other contexts (#20).


  • Students work one-on-one with an educator.



  • Ask the child to point and read each number on the number line (Appendix A).
  • Put the deck of number cards (Appendix B) upside down.
  • Invite the child to select a number card, read the number and build the corresponding “tower”.
  • The child continues the activity until they have turned over every card and completed the staircase of towers from one to ten.
  • Ask children comparison questions – How many more cubes are there in Tower 5 than there are in Tower 4?

Look Fors

  • Do children have one-to-one correspondence when counting?
  • How comfortably can children recognize the symbolic number and build the corresponding tower?
  • Can children answer comparison questions accurately?
