Eighth Class - Number

Standard 8.NS.1 - Practice divisibility rules with numbers up to 10,000.

Included Skills:

Number Systems; N: the set of natural numbers, N = {1,2,3,4...}; Z: the set of integers, including 0; Q: the set of rational numbers; R: the set of real numbers; R/Q: the set of irrational numbers
The binary operations of addition, subtraction multiplication and division and the relationships between these operations, beginning with whole numbers and integers. They explore some of the laws that govern these operations and use mathematical models to reinforce the algorithms they commonly use. Later, they revisit these operations in the context of rational numbers and irrational numbers (R/Q) and refine, revise and consolidate their ideas. Students learn strategies for computation that can be applied to any numbers; implicit in such computational methods are generalisations about numerical relationships with the operations being used.
Students articulate the generalisation that underlies their strategy, firstly in the vernacular and then in symbolic language.
Problems set in context, using diagrams to solve the problems so they can appreciate how the mathematical concepts are related to real life. Algorithms used to solve problems involving fractional amounts.
