## The Mathematics Curriculum

## Mathematics - The Montessori Way

Montessori maths equipment is unique in its well thought out hands on equipment that introduces ideas to students systematically and helps them see the big picture. A **key feature of Montessori maths is colour coding**. Hands on beads for the number four are made of four interlocking yellow beads. The colour for five is light blue. Place value is also colour co-ordinated for example units are always represented with green, tens with blue and hundreds with red. This colour coding system helps give students a visual reminder of what they are learning about and helps them internalise ideas.

Montessori maths equipment includes hands on materials for teaching about angles, algebra, geometry, number, fractions, decimals and basic facts.

Montessori uses the Montessori Great Stories to look at how maths has been used across cultures and time to help humans, being in New Zealand we take a particular interest in how Māori have used number and math through concepts as vast as kowhaiwhai to building.

## Our Approach to Mathematics

We have a thorough knowledge of the New Zealand maths curriculum used in state schools. By the end of year 8 our students will have covered the same concepts as their peers in state schools but using a different curriculum. It is our aim for all our students to go onto succeed well with maths at secondary school

We use the

**Montessori maths equipment and montessori inspired ideas to help our students learn**the same concepts they would at a normal skill but with lots of hands on tools. The tools are always present in the room which allows for students to use them whenever they need them or want to explore a concept.We

**encourage individual and group learning**in maths.## Numbers

- Whole numbers from 1 to 1,000 (ordering numbers and learning place value)
- Number lines
- Positive and negative numbers
- Odd and even numbers
- Commutative and associative properties
- Skip counting (by a number to its cube)
- What zero does
- Hierarchies (formation, reading, and writing of numbers to 1,000,000)
- Rounding to the nearest ten, hundred, orthousand
- Estimation e.g. 290 + 789 is close to 1000
- Expanded notation
