Cam and Zoe Learn their Shapes, Colours and Counting at the Park is a great way to introduce and teach basic shapes, colours and counting to your children. Cam and Zoe make their way around the park determining the shapes, colours and count of things someone might find while playing at a park. While doing this, they invite the reader to help them. Cam and Zoe Learn their Shapes, Colours and Counting at the Park is the third instalment in the Cam and Zoe series of children's books written and illustrated by Karyn M Olsen. An Aussie mum of two, it is Karyn's hope that your children will enjoy her books as much as her own do.
