Miss Gargan told the children that we have been coming to school for
"one day less than 1/2 of 100"
and we had to work it out.
We used the abacus to work out what 1/2 of 100 is. Charlotte showed us 1/2 of 100 and it looked like this ...
We counted in 5's...5, 10, 15, 20, 25, 30, 35, 40, 45, 50.
We also could show 1/2 of 100 like this ...
We counted this in 10's...10, 20, 30, 40, 50
1 less than 50 looks like this ...
So we are up to day 49!
We updated our display to show 49 in lots of different ways -
Then we got a challenge -
The children worked in small groups to solve this problem - well done Room 6!
