Making 100s

Back in April or May, two children in the class were playing with the 100 tray. They like it because it's the biggest. They started to put the hundreds they were making on the carpet and make more, so I put down some masking tape to give them a border to work to. More children joined and got obsessed, eventually they made this:

We counted what we had afterwards. And then discussed our counting:

  • When we were counting, each had their own pattern and some of them were the same.
  • 100 white piece fit in a tray.
  • When we counted 100, 200, 300, 400, 500, 600, 700, 800, 900 ____ . Some people were saying ten-hundred because it’s kind of confusing.
  • Also we were saying 10, 20, 30, 40, 50, 60, 70, 80, 90, twenty! Because the 90 sounds like 19.
  • If we put rods in the orange boxes, then not all of the colours we put made 100.
  • That we had to be careful and not break the things we made.
  • We got to 10,000!
