Counting Squares

The students were presented with a picture that had a heap of red and yellow Unit Tiles.

What do you wonder?

  • Tracey “Why does red and yellow? Why are they not rectangles?”
  • Patrick “Who takes yellow and red to mix it.”
  • Kenan “Why yellow and red is putting in?”
  • Mason “What does it mean?”
  • Olivia “Why don’t they have blue and green?”

 Estimate how many squares are in the pile?  

Next, the children estimated how many Unit Tiles there were in the pile. They noted this down.

How many red?

How many yellow?

How many Unit tiles we used to make the pattern?

Then, we watched a video that gave the children more clues. The video stops midway, showing an incomplete pattern. The children used pictures to draw and share the complete pattern, and to find out how many tiles were used in all.

Finally, they were able to record how many red and yellow tiles were used to make the pattern.

Through this task the children were able to:

-estimate

-share their thinking

-document ideas using drawings and numbers

-problem-solve

-work in collaborative groups
