Grade 6 - Patterning and Algebra

Standard 6.PA.2 - Practice evaluating variable expressions with whole numbers.

Included Skills:

Variables, Expressions, and Equations

• demonstrate an understanding of different ways in which variables are used (e.g., variable as an unknown quantity; variable as a changing quantity);

• identify, through investigation, the quantities in an equation that vary and those that remain constant (e.g., in the formula for the area of a rectangle, A = (b x h)/2 the number 2 is a constant, whereas b and h can vary and may change the value of A);

• solve problems that use two or three symbols or letters as variables to represent different unknown quantities (Sample problem: If n + l = 15 and n + l + s = 19, what value does the s represent?);

• determine the solution to a simple equation with one variable, through investigation using a variety of tools and strategies (e.g., modelling with concrete materials, using guess and check with and without the aid of a calculator) (Sample problem: Use the method of your choice to determine the value of the variable in the equation 2 x n + 3 = 11. Is there more than one possible solution? Explain your reasoning.).
