Managing the transition to Intermediate and Secondary


Matching Numicon Big Ideas to Numicon, Discovering Maths and MyiMaths

Numicon Big Ideas is a programme for students who would benefit from revisiting or learning for the first time, key concepts from Levels 1, 2 and 3 of the NZ Curriculum.  This will help them transition to secondary levels in Years 8 and 9.  It was originally intended to be a catch-up for students in Years 5 onwards, but with the impact of the Covid epidemic this resource has shown to make a significant difference for students in Years 7 - 9.


Using the proven approach, Big Ideas reteaches these concepts, using structured imagery and apparatus to teach, reinforce and embed the ideas.  It will also break down any misconceptions a student might have. The key mathematical ideas are common areas for everyone learning maths and how to solve problems.

These big ideas are:  Place value and the number system, addition, subtraction, mulitplication, division, fractions, decimals and percentages.


We have correlated the Big Ideas sessions to match the Numicon, Discovering Mathematics and MyiMaths resources, all published by Oxford University Press. These links allow teachers to identify where the teaching plans for Years 7 - 9 combine with Big Ideas and where they can provide students with the opportunity to develop knowledge of these concepts. It could be that students have never learned these concepts so links to the earlier book are also included. To receive these correlations, contact Margi


We hope that the combination of these resources will support students who have gaps or weaknesses in their knowledge from concepts in NZC Levels 2 and 3 which could be more pronounced because of disruptions in their learning.

Getting Started

A beginning assessment (Assessment A) is provided, but it is recommended to use this assessment along with the teaching sessions. The information is given on each session card. The majority of the students could not successfully answer all the questions. There is another assessment (Assessment B) provided at the end of the Big Ideas series of lessons.


You can join one of our courses or zooms, message us through our facebook group Numicon NZ Users or contact one of our consultants for more help in getting started.
