Nearly half of the nation’s children entered school last fall below year level in at least one subject, most often in reading or maths. 1, 2, 3

Number Sense provides a different approach to learning maths, one that is based upon the work of mathematics expert Chris Woodin, Ed.M.

Based upon decades of teaching experience, Number Sense’s innovative and research-based methods teach early maths concepts, addition, and subtraction to build a solid foundation of number sense.

“Number Sense is not another skill and drill program. It provides students with the ability to recognise patterns of quantities and associate them with written numbers and facts. Kids take familiar patterns apart, then create facts as they reassemble them while describing the process.”

Chris Woodin Ed.M

Structured and systematic learning development uses a combination of whole-to-part processing, linking quantities to shapes and numbers, and multisensory lessons, activities, and games. This is beneficial for all children learning maths, and children who have language-based learning difficulties such as dyslexia, dyscalculia, and dysgraphia.

Number Sense helps shape the building blocks necessary for understanding early maths skills, building your child’s confidence, fluency, and accuracy with basic maths facts.

Join Yetis and Hairies on an adventure through the Number Sense Islands

1. Number Sense Island

Early maths struggles begin when students fail to develop a clear link between number names and the quantities they represent. Once these associations are learned, students have the important ability to compare numbers.

The Number Sense program trains students to immediately recognise patterns of 5 and 10. This makes it easier for them to compare quantities and to understand the different values.

2. Add-Lantis Island

Children dive undersea to the Island of Add-Lantis to learn addition and subtraction facts 6-10, 11-20,  2-digit and 3-digit numbers.


3. Division Castle Island

Help to repair the castle, meet a friendly giant and enter Baron Von Double’s games. Learn multiplication and division facts following the highly effective whole-to-part methodology.

“He enjoyed the funny videos and games, especially the video at the end of the Number Bubbles games. The fact that he spent a full hour engaged with it speaks very highly about his enjoyment of it.”
