# 9 Mathematics

#### Course Description

**Teacher in Charge: ** Mr D. Galvan

Welcome to Mathematics at Tauranga Boys’ College. The course is based on the NZ Curriculum Levels 3, 4, 5 (CL3/4/5). The aim of this course is to develop Mathematical thinking and enhance problem-solving strategies.

There are many important links between Mathematics and the world around us.

Number - the basic life skills of budgeting, wealth, and purchasing.

Algebra - creating code and formula to find solutions.

Geometry - shapes, and angles are everywhere.

Probability - discovering the various possible outcomes.

Measurement - applying Number skills to practical problems.

Statistics - using data to make informed choices.

#### Contributions and Equipment/Stationery

Bring Your Own Device (BYOD)

Teachers are upskilling their knowledge regarding integrating technology into Mathematics. Students will use their devices to complete additional tasks online. These tasks will complement the work that is being covered in class.

Please help your son to organise himself so that his allocated tasks are completed on time. This may need to be completed as homework. If you have any queries regarding his homework then please contact your son’s teacher in the first instance.

Calculators

There is no need for your son to have a calculator for the Year 9 Mathematics course. We will teach a range of numeracy strategies to encourage mathematical thinking and develop a better understanding. (The Year 10 boys are strongly encouraged to use a scientific calculator for the Year 10 Course - cell phone calculators and BYOD calculators cannot be used in tests).
