Grade 6 - Patterns and Relations
Standard 6.PR.3 - Practice writing variable addition, subtraction, multiplication and division sentences to represent a word problem.
Included Skills: Algebra
Extend understanding of patterns and relationships by using expressions and equations involving variables. • Analyze patterns arising from the determination of perimeter of rectangles and generalize an equation describing a formula for the perimeter of all rectangles. • Analyze patterns arising from the determination of area of rectangles and generalize an equation describing a formula for the area of all rectangles. • Describe and represent geometric patterns and relationships relevant to First Nations and Métis peoples and explain how those patterns or relationships could be represented mathematically. • Develop and justify equations using letter variables that illustrate the commutative property of addition and multiplication (e.g., a + b = b + a or a × b = b × a). • Generalize an expression that describes the relationship between the two columns in a table of values. • Write an equation to represent a table of values. • Generalize an expression or equation that describes the rule for a pattern (e.g., the expression 4d or the equation 2n + 1 = 8). • Provide examples to explain the difference between an expression and an equation, both in terms of what each looks like and what each means.
