O is for One Hundred

Today we had a big catch up on our 100 days at school.  We have been counting each day we have been coming to school since the beginning of the school year.  When we get to 100 days we will celebrate!  We have been so busy lately that we have lost track of the day.

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!
