## A Teacher’s Guide

This guide is intended to support teachers’ ongoing efforts in building students’ knowledge and skills in mathematics. It focuses attention on the content of expectations in The Ontario Curriculum, Grades 1–8: Mathematics, 2005 that deal with fundamental mathematics concepts and skills (specifically, expectations in the Number Sense and Numeration strand and expectations that relate to number properties in the Patterning and Algebra strand). The guide outlines steps to achieving the knowledge and skills described in these expectations and suggests how to make more timely connections that will better support student learning. A strong foundation in the concepts and skills emphasized here will prepare students for success in high school, and ensure that they have a set of essential skills for employment and responsible citizenship in the future.

Becoming highly skilled at arithmetic requires the development of number sense alongside procedural and factual knowledge as well as the mathematical principles that govern how the operations are related to one another.
(Bruce & Chang, 2013, p. 14, citing Baroody & Dowker, 2003)

## What are the fundamental math concepts and skills?

Fundamental math skills, and the concepts that underpin them, may be categorized according to the following framework:

## Why is it important for students to master the fundamentals of math?

Understanding how numbers work is foundational to all aspects of mathematics. As students progress through the grades, they learn about different types of numbers and how those numbers behave when operations are applied to them. Recognizing and understanding number properties is foundational to arithmetic and algebra.

Students need to be fluent with number facts in order to perform mathematical calculations efficiently and accurately, whether mentally or by applying algorithms on paper. The goal is for students to develop automaticity, which is the ability to use skills or perform mathematical procedures with little or no mental effort. Automaticity with math facts also supports students in critical thinking and problem solving.

The more automatically a procedure can be executed, the less mental effort is required. Since each person has a limited amount of mental effort that he or she can expend at any one time, more complex tasks can be done well only when some of the subtasks are automatic.
(National Research Council, 2001, p. 351)

Most students learn math facts gradually, over a number of years, using tools such as manipulatives and calculators. Mastery comes with practice, and practice helps consolidate knowledge. Students will draw on their ability to apply math facts with automaticity throughout secondary school, as they manipulate algebraic expressions and equations.

Mental math skills involve the ability to perform mathematical calculations in the mind, without relying on pencil and paper. Mental math skills enable students to estimate answers to calculations, and so be able to work quickly on everyday problems and judge the reasonableness of answers calculated formally.

It is important for students to become proficient in using the operations of addition, subtraction, multiplication, and division in the elementary grades. Even in today’s technological age, people use calculations every day – for example, to verify that they’ve received correct change or to estimate how many cans of paint they need to paint a room. In the early grades, students learn about operations with whole numbers, and this sets the stage for working with decimals, fractions, and integers later on.

Though individual students may progress at different rates, generally speaking, addition/ subtraction facts should be mastered by the end of Grade 3, and multiplication/division facts should be mastered by the end of Grade 5 (Chapin & Johnson, 2006) – but students should continue to practise and extend their proficiency throughout the grades and in the context of learning in all the strands of the mathematics curriculum.

## How can educators help students master the fundamentals?

Strategies help students fian answer even if they forget what was memorized. Discussing math fact strategies focuses attention on number sense, operations, patterns, properties, and other critical number concepts.
(O’Connell & SanGiovanni, 2011, p. 5)

Fluency with basic math facts is fostered through instruction that highlights strategies for remembering facts, focuses on making sense, and integrates math-fact learning into other aspects of math learning, such as developing computational skills. Repeated practice, or “drill”, by itself may improve speed, but it does not contribute to understanding and it is not sufficient to guarantee immediate recall. Strategies such as learning related math facts together – for instance, “× 5 is half of × 10” – enable students to understand the inter- connectedness of math facts and also make it easier to remember them.

Children should learn their number facts. However, they would benefit from learning these facts by using an increasingly sophisticated series of strategies rather than by jumping directly to memorization.
(Lawson, 2016, p. 4)

Strategies that can help students commit basic facts to memory include:

## How can educators use this guide to support students in learning the fundamental math concepts and skills?

The following tables, for Grades 1 to 3, Grades 4 to 6, and Grades 7 and 8, outline a “scope and sequence”, from The Ontario Curriculum, Grades 1–8: Mathematics, 2005, for developing and mastering the fundamentals, based on the framework outlined on page 2 of the present document. As educators support students in meeting the curriculum expectations, they help them master the skills and knowledge indicated in the tables for each grade by the end of the school year, giving consideration to individual students’ learning needs.

The fundamental concepts and skills outlined in the following tables can be developed in connection with learning in all strands of the math curriculum – Number Sense and Numeration, Geometry and Spatial Sense, Measurement, Data Management and Probability, and Patterning and Algebra.

In order to become fluent in calculation, students must have efficient, accurate methods supported by number and operation sense. They must learn how algorithms work.
