## Overview

Mathematics is a powerful tool used every day to solve real-life problems. It includes arithmetic, geometry, data, statistics, and probability.

Through mathematics, students learn critical thinking skills to analyze information and make decisions in a variety of situations. For example, they rely on mathematics to tell time, manage a budget, change a recipe, play a board game, build a Lego® model, or make a schedule.

Studying mathematics can lead to jobs in computer science, construction, artificial intelligence, teaching, the restaurant industry, and many other fields.

## Shifts in K-6 mathematics

These are the main shifts in knowledge and skill requirements to the new K-6 mathematics curriculum from the current curriculum.

In mathematics, students will learn about numbers and operations, geometry, and measurement of length, area, volume, and time.

• Count and represent quantities within 10
• Recognize 2-D and 3-D shapes in the environment
• Compare objects by length, area, mass, and capacity
• Order a sequence of events according to time
• • Recall addition number facts to a sum of 20 and related subtraction facts
• Compare and sort 2-D and 3-D shapes
• Order objects according to length
• Identify cycles of time from nature and calendars
• • Add and subtract numbers within 100
• Use angles or sides to sort shapes, and describe the sorting rule
• Measure length in centimetres
