The 65 pupils chalked up 100 days at school and decided to celebrate their tonne in style.

The youngsters dressed up as 100 year olds and cut a celebratory cake. They imagined an exercise routine that could be done 100 times.

The pupils drew up a list of 100 things they like and 100 things they didn’t and they imaged what life would be like if they were 100 years old.

The kindergarten teachers also broke out their “dress-ups” and got in on the fun.

Teacher Dimity Balding said the pupils had been particularly amused by apps which “aged” photos and made them appear to be centenarians.

“It has been a lot of fun.” Ms Balding said.
