The series introduces new mathematics concepts to preschool children using the Concrete Pictorial Abstract (C-P-A) approach. Children are guided through systematic variation that reinforces the mathematical concepts that will help to build a strong foundation. First, children make sense of mathematics concepts using materials they can play with. Next, they are shown the same concepts with pictures they have played with or counting units. Lastly, children revisit the concepts expressed in numerals. Concepts learnt during earlier lessons are then revisited at greater difficulty in later lessons. This spiral approach helps children recall, consolidate and extend what they have learnt. Digital activities are also available to provide students with opportunities to practise and consolidate their understanding of concepts. Extension units cover topics that are beyond the syllabus which helps to challenge the children’s abilities and expand their knowledge of key mathematics concepts.
