Our youngest students celebrated 100 days of school today by dreaming big.
Knox Grammar School
Boys at the Prep School dressed as what they would like to be when they grow up and decorated their own cupcake to celebrate the milestone.
Astronauts, engineers, firefighters, police officers, builders, doctors, scientists and athletes were a few of the students' choices.
As well as the chance to be creative by decorating cupcakes, the boys also created special '100' sunglasses to take home as a memento.
At Wahroonga Prep, the students marked the day with a variety of festivities – Years 3 and 4 visited to help the students decorate '100' crowns, and at Recess the children enjoyed cupcakes in the design of a '100' chart.
