Below you will find videos modelling the abstract, formal calculations methods used in Primary 7. Each video links directly to the pdf document (Primary 7 Calculation Strategies) that can be found below. The pdf document details:
Concrete, pictorial and abstract approaches towards achieving each area of learning.
We hope the combination of videos and the written methods may prove useful in helping families support their child's learning at home.
