Secondary 2 - Number and Algebra

Standard 8.NA.7 - Practice evaluating variable expressions with whole numbers.

Included Skills:

Equations and inequalities

• 7.1 solving linear equations in one variable (including fractional coefficients)

• 7.2 concept and properties of inequality

• 7.3 solving simple fractional equations that can be reduced to linear equations such as x/3 + (x-2)/4 = 3, 3/(x-2) = 6

• 7.4 graphs of linear equations in two variables (ax + by = c)

• 7.5 solving simultaneous linear equations in two variables by:

- substitution and elimination methods

- graphical method

• 7.6 formulating a linear equation in one variable or a pair of linear equations in two variables to solve problems

• 7.7 formulate inequalities from real-world contexts.

• 7.8 Use Graphmatica, applets or other software to draw the graph of ax + by = c (a straight line), check that the coordinates of a point on the straight line satisfy the equation, and explain why the solution of a pair of simultaneous linear equations is the point of intersection of two straight lines.

• 7.9 Draw the lines x = a and y = b, and describe the lines and their gradients.

• 7.10 Use the Algebar application in AlgeTools to formulate linear equations to solve problems (Students can draw models to help them formulate equations.)
