# Primary/K-6: Number Number Sense is a vital skill that your child must learn.  While the numbers and their properties may become more sophisticated as your child grows, he/she will learn about numbers throughout his/her maths journey.

We know how fundamental learning about number is and that is why it is part of every step on our Rainbow Ladder Maths.

"Number sense develops gradually over time as a result of exploring numbers, visualising them in a variety of contexts, and relating them in ways that are not limited by traditional algorithms"
Sood and Jitendra (2007)
