# Unifix Counting Towers

## Curriculum Goal

#### Kindergarten: Demonstrating Literacy and Mathematics Behaviour

• 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).

## Context

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

## Lesson

• 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?
