Our centre has two main rooms, the preschool "Rainbow" and the toddler "Butterfly" room. However, they are only by classification and our program caters for the 5 broad groups of children's abilities and interests: infants, toddlers, junior preschoolers, preschoolers and kindergarten children. This is a key part of our learning program as depicted in our learning tree. Teachers understand that at certain times, in the preschool room there may be junior preschoolers, preschoolers as well as able kindergarten children, and they may not necessarily follow the age of a child. Similar in the toddler room there are, infants, toddlers, junior preschoolers and by the end of the year, ready preschoolers. At times, we find preschoolers may want to be with their younger siblings in the Butterfly room and the flexibility for children to be around and to play with older and younger children is in itself a great attribute that can only be tried and learnt in a mixed group situation. Learning from older peers in the classroom and vice versa is a wonderful experience to witness.
