Math Grade 8 -(10hours)

Number

Students use scientific notation such as 5.46 × 106 to understand, represent and compare very large and small numbers more easily, which is often required in Science. Students use fractions, decimals and per cents interchangeably, and should be able to recall square numbers to 144 and their square roots. Students solve problems that involve proportions (for example, determining the percentage increase or decrease in the attendance of a show) and whole numbers, fractions, decimals, integers and exponents.

Algebra

Students continue to develop their understanding of patterns, including those that involve integers. They use algebraic notation, such as, s = d/t, to represent the relationship between speed, distance and time. They solve algebraic equations involving multiple terms, integers and decimal numbers. Students write code to create a line or curve that falls between the greatest number of data points. They also use modelling for real-life situations, such as making predictions about future fundraisers based on the funds raised from past fundraisers.

Data

Students continue to build their data skills. They analyze data that is presented in more complex ways, such as in scatter plots, that show the relationship between two variables. In addition, students continue to increase their understanding of probability by comparing the outcomes of more complex experiments.

Spatial sense

Students continue to develop spatial sense as they study right-angle triangles. They learn that if two side lengths are known, then the length of the third can be figured out without measuring it, using the Pythagorean Theory. Students learn how to calculate unknown angles by applying the angle properties of intersecting and parallel lines. Students also build their understanding of very large units such as a terabyte and very small units like a nanosecond that are used in current technologies.

Financial literacy

Students learn to create a plan to reach financial goals and identify ways to maintain balanced budgets. Students compare different ways that consumers can get value for their money when spending, such as using reward programs or taking advantage of sales. Students investigate the concepts of simple and compound interest using technology, (for example, a spreadsheet program) and explain how interest affects long-term financial planning.

Social emotional learning skills and mathematical processes

Students continue to build healthy relationship skills. They will use data in an infographic to communicate and tell a story and build awareness about others. This will help them understand things they have in common with their peers and what makes different groups unique.
