The Mathematical Processes

"The mathematical processes cannot be separated from the knowledge and skills that students acquire throughout the year. Students must problem solve, communicate, reason, reflect, and so on, as they develop the knowledge, the understanding of concepts, and the skills required in all the strands in every grade."
The Ontario Curriculum, Grades 18: Mathematics, 2005
The mathematical processes are:

The Kindergarten Program

"Mathematics in the Kindergarten program builds on children’s desire to make sense of their world, and helps them develop and demonstrate their mathematical understanding. Young children use mathematics intuitively and develop their understanding of mathematics through their individual approaches to learning, as well as through their prior experience of their linguistic, family, cultural, and community backgrounds. It is therefore important for children’s existing conceptual understanding of mathematics to be valued and for children to be introduced to mathematical concepts in an appropriate manner and at an appropriate time in their development."
The Kindergarten Program, 2016
As children progress through the Kindergarten program, they:
demonstrate an understanding of numbers, using concrete materials to explore and investigate counting, quantity, and number relationships
measure, using nonstandard units of the same size, and compare objects, materials, and spaces in terms of their length, mass, capacity, area, and temperature, and explore ways of measuring the passage of time, through inquiry and playbased learning
describe, sort, classify, build, and compare twodimensional shapes and threedimensional figures, and describe the location and movement of objects through investigation
recognize, explore, describe, and compare patterns, and extend, translate, and create them, using the core of a pattern and predicting what comes next
collect, organize, display, and interpret data to solve problems and to communicate information, and explore the concept of probability in everyday contexts
apply the mathematical processes to support the development of mathematical thinking, to demonstrate understanding, and to communicate thinking and learning in mathematics, while engaged in playbased learning and in other contexts

For example, the mean of 10, 20, and 60 is (10 + 20 + 60) ÷ 3 = 30. A change in the data produces a change in the mean, similar to the way in which changing the load on a lever affects the position of the fulcrum if balance is maintained.

12 Relative frequency.The frequency of a particular outcome or event expressed as a percent of the total number of outcomes. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.132)
13 Measure of central tendency. A value that summarizes a whole set of data; for example, the mean, the median, or the mode. A measure of central tendency represents the approximate centre of a set of data. Also called central measure. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.128)
14 Theoretical probability. A mathematical calculation of the chances that an event will happen in theory; if all outcomes are equally likely, it is calculated as the number of favourable outcomes divided by the total number of possible outcomes.

1 Rational number. A number that can be expressed as a fraction in which the denominator is not 0. (The Ontario Curriculum Grades 18, Mathematics, 2005, p. 131)
2 Multistep problem. A problem that is solved by making at least two calculations The Ontario Curriculum Grades 18, Mathematics, 2005, p. 128)
3 Order of operations. A convention or rule used to simplify expressions. The acronym BEDMAS is often used to describe the order: – brackets – exponents – division or multiplication, whichever comes first – addition or subtraction, whichever comes first (The Ontario Curriculum Grades 18, Mathematics, 2005, p. 129)
4 Perimeter. The length of the boundary of a shape, or the distance around a shape. For example, [...] the perimeter of a circle is its circumference. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.130)
5 Quadrilateral. A polygon with four sides (The Ontario Curriculum Grades 18, Mathematics, 2005, p.131)
6 Property (geometric). An attribute that remains the same for a class of objects or shapes. A property of any parallelogram, for example, is that its opposite sides are congruent. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.168)
7 Similar. Having the same shape but not always the same size. If one shape is similar to another shape, there exists a dilatation that will transform the first shape into the second shape. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.132)
8 Polyhedron. A threedimensional figure that has polygons as faces. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.130)
9 Pythagorean relationship. The relationship that, for a right triangle, the area of the square drawn on the hypotenuse is equal to the sum of the areas of the squares drawn on the other two sides. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.131)
10 Coordinate plane. A plane that contains an xaxis (horizontal) and a yaxis (vertical), which are used to describe the location of a point. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.122)
11 Linear equation. An algebraic representation of a linear relationship. The relationship involves one or more firstdegree variable terms; for example, y = 2x – 1; 2x + 3y = 5; y = 3. The graph of a linear equation is a straight line. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.127)
12 Categorical data. Data that can be sorted by type or quality, rather than by measured or counted values. Eye colour and favourite food are examples of categorical data. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.121)
13 Discrete data. Data that can include only certain numerical values (often whole numbers) within the range of the data. Discrete data usually represent things that can be counted; for example, the number of times a word is used or the number of students absent. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.123)
14 Continuous data. Data that can include any numerical value that is represented on a number line and that falls within the range of the data, including decimals and fractions. Continuous data usually represent measurements, such as time, height, and mass. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.122)
15 Histogram. A type of bar graph in which each bar represents a range of values, and the data are continuous. No spaces are left between the bars, to reflect the continuous nature of the data. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.125)
16 Scatter plot. A graph designed to show a relationship between corresponding numbers from two sets of data measurements associated with a single object or event; for example, a graph of data about marks and the corresponding amount of study time. Drawing a scatter plot involves plotting ordered pairs on a coordinate grid. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.126)
17 Measure of central tendency. A value that summarizes a whole set of data; for example, the mean, the median, or the mode. A measure of central tendency represents the approximate centre of a set of data. Also called central measure. (The Ontario Curriculum Grades 18, Mathematics, 2005, p.128)
18 Attribute. A quantitative or qualitative characteristic of a shape, an object, or an occurrence; for example, colour, size, thickness, or number of sides. An attribute may or may not be a property. (The Ontario Curriculum Grades 18, Mathematics, 2005, p. 120)
19 Experimental probability. The likelihood of an event occurring, determined from experimental results rather than from theoretical reasoning. (The Ontario Curriculum Grades 18, Mathematics, 2005, p. 124)
20 Theoretical probability. A mathematical calculation of the chances that an event will happen in theory; if all outcomes are equally likely, it is calculated as the number of favourable outcomes divided by the total number of possible outcomes. (The Ontario Curriculum Grades 18, Mathematics, 2005, p. 133)
21 Complementary events. Two events that have no outcome(s) in common but that account for all possible outcomes of an experiment. For example, rolling an even number and rolling an odd number using a number cube are complementary events. The sum of the probabilities of complementary events is 1. (The Ontario Curriculum Grades 18, Mathematics, 2005, p. 121)
