Extract from Ontario curriculum Mathematics:

1. Number Sense and Numeration

It is important for students to develop the mathematical competence that comes from understanding numbers, number systems, and their related operations.

Number is a complex and multifaceted concept. A well-developed understanding of number includes a grasp not only of counting and numeral recognition but also of a complex system of more-and-less relationships, part-whole relationships, the role of special numbers such as five and ten, connections between numbers and real quantities and measures in the environment, and much more. Experience suggests that students do not grasp these relationships automatically. It is the teacher's job to provide students with a broad range of activities that will help them develop many of these ideas about number.

Helping students to understand numbers must always include introducing them to procedures for accurately performing operations with numbers. Key facts and processes must be mastered. Students also need to develop "number sense". Number sense includes:

*       an appreciation of and ability to make quick order-of-magnitude approximations with emphasis on quick and accurate estimates in computation and measurement;

*       the ability to detect arithmetic errors;

*       knowledge of place value and the effects of arithmetic operations;

*       a grasp of ideas about the role of numbers and about their multiple relationships;

*       an appreciation of the need for numbers beyond whole numbers.

Mental Mathematics and Estimation

By the end of Grade 6, students should have consolidated their understanding of basic computational facts and be able to use computational strategies to do mental mathematics. This ability develops over time, supported by regular practice, as students identify relationships between numbers and learn when and how to use the various operations effectively. Techniques of mental mathematics should be introduced along with concepts of place value and the use of pencil-and-paper calculations. For example, the mental skill of adding numbers ending in zero, such as 20 + 40 + 70, can be learned by a student who understands place value and can add 2 + 4 + 7. Instruction in computational estimation should include not only applications involving whole numbers and decimals, but also those involving fractions and percent. Early experiences in estimating with percent and fractions can help students develop number sense.

Pencil-and-Paper Computation

Students (and adults) require facility with pencil-and-paper computations. It is important for pencil-and-paper computational procedures to be introduced through the use of concrete materials. Students should use these materials until they understand the concepts well enough to move from the manipulative stage to the semiconcrete medium of pictures and then to the abstract form of numbers on a page.

Many methods of pencil-and-paper calculation have been appropriately replaced by operations of a calculator or computer. For example, long division, operations with long lists of large numbers, and the calculation of square root can be done more efficiently using technology. Teachers should also provide students with a variety of experiences and investigations involving number.

Fractions and Rationals

Concepts and operations with fractions should be introduced using concrete materials. Models, tiles, manipulatives, and diagrams should be used to relate fractions to decimals, to find equivalent fractions, and to explore operations with fractions and decimals. Fraction symbols build on the understanding developed in these ways. Mathematics instruction should help students gain conceptual understanding as well as use fractions and rational numbers effectively and accurately.

It is recommended that, initially, simple denominators such as 2, 3, 4, 5, and 10 be used. As students gain more experience and skill in working with fractions, denominators such as 6, 8, and 12 can be included. Later, the focus shifts to using fractions in ratios, rates, and percent. As well, students will extend their fraction sense to include skill in operations with fractions. It should be remembered, however, that the use of fractions in real-life situations often involves estimating (e.g., "My friend lives half a block from here"), and this skill should be developed along with accurate calculation.

Calculators

The ability to use calculators intelligently is an integral part of number sense. It should be noted that the use of calculators does not do away with the necessity for students to master the fundamental mathematical operations. Students should use calculators in their schoolwork, just as adults use calculators for many purposes in the course of their daily lives. More importantly, students must learn when it is appropriate to use a calculator and when it is not. They must learn from experience with calculators when to estimate and when to seek an exact answer, and how to estimate answers to verify the plausibility of calculator results. Calculators allow teachers to engage students in meaningful mathematical investigations, such as solving science problems with large numbers, before their skill with pencil-and-paper computation is equal to the task. Proper calculator use stimulates the growth of number sense in students.

Computers

The computer is an important tool used by mathematicians to perform a wide variety of tasks; the ability to use computers effectively and appropriately is central to students' development of mathematical competence.

An important use of computer software is to engage students in the exploration of concepts. Computer programs should help students develop number sense and deal with large amounts of data in an organized way. Spreadsheets should be used by all students to manage and operate on long lists of numbers. Also, the computer can serve as an aid to students in clarifying operations rules that will help them develop concepts used in early algebra.

2. Measurement

Measurement concepts and skills are directly applicable to the world in which students live.

The topic of measurement lends itself naturally to the introduction of fractions and decimals. It also requires students to be actively involved in solving and discussing problems. Students should be encouraged to compare objects directly by covering them with various units and counting the units. Concrete experience in solving measurement problems is the best foundation for using instruments and formulas. As students develop increasing skills in numeration, they can be challenged to undertake increasingly complex measurement problems, thereby strengthening their facility in both areas of mathematics.

Estimation activities are important to help students become familiar with different measures and the process of measuring, and to gain an awareness of the size of units. Often, only an estimate is required in order to make a decision about the solution to a problem. Students should develop a fund of informal measurement guidelines, so that they know, for example, that their fingers are about 1 cm wide, that a can of pop is about 350 mL, and so on. These guidelines will help them estimate sizes in the world around them.

3. Geometry and Spatial Sense

Spatial sense is the intuitive awareness of one's surroundings and the objects in them. Geometry helps us represent and describe, in an orderly manner, objects and their interrelationships in space. A strong sense of spatial relationships and competence in using the concepts and language of geometry can improve students' understanding of number and measurement.

Spatial sense is necessary for interpreting, understanding, and appreciating our inherently geometric world. Insights and intuitions about the characteristics of two-dimensional shapes and three-dimensional figures, the interrelationships of shapes, and the effects of changes to shapes are important aspects of spatial sense.

Students need to visualize, draw, and compare shapes in various positions in order to develop their spatial sense. Although students do need to learn the formal language of geometry, instruction in the correct terminology should not be the only focus of the program. Students must also explore and understand relationships among figures. As students' conceptual understanding develops, technical terms will become meaningful to them, and they will develop the ability to use correct terminology in presenting their own views and arguments.

Students' experiences with graphing and interpreting should include using technology to explore both linear and non-linear relations. All students should have access to computers and graphing calculators as powerful tools that can help them expand their understanding of analytic geometry.

4. Patterning and Algebra

One of the central themes in mathematics is the study of patterns and functions. This study requires students to recognize, describe, and generalize patterns and to build mathematical models to predict the behaviour of real-world phenomena that exhibit observed patterns. Exploring patterns helps students develop both mathematical competence and an appreciation of the aesthetic qualities of mathematics.

In Grades 1 to 3, instruction should focus on helping students identify regularities in events, shapes, designs, and sets of numbers. Students will begin to see that regularity is the essence of mathematics. Physical materials and pictorial displays can be used to help students recognize and create patterns and relationships. Through observing varied relationships of the same pattern, students can begin to identify its properties. Encouraging students to label and describe patterns, using letters and other symbols, prepares them to use variables in the future.

In Grades 4 to 6, the focus of instruction shifts from exploring patterns to exploring functions. When students use graphs, data tables, expressions, equations, or verbal descriptions to represent a single relationship, they discover that different representations yield different interpretations of a situation. Through such activities, students learn informally that functions are things that can vary (variables) and that therefore have a changing relationship with other variables: changes in one variable result in changes in another.

Algebra is the language through which most of mathematics is communicated. The focus of the study in Grades 7 and 8 is first on understanding how the language of algebra can be used to generalize a pattern or a relationship. A second focus is on using algebra as a problem-solving tool – a means of clarifying concepts at an abstract level before applying them. Experience with this process often helps students to develop generalizations and insights that extend their learning beyond the original application.
