This is a mathematics worksheet with worked answers for a yr 9 or 10 (stage 5) student studying indices. There are 25 equations to solve. Worked answers are provided at the back.
This worksheet covers the following NSW syllabus dot points for 2018:
Extend and apply the index laws to variables, using positive-integer indices and the zero index
Simplify algebraic products and quotients using index laws
This is a pictorial information sheet to help show the effect Le Chatelier’s principle has on equilibrium with temperature, concentration and pressure.
For the current HSC syllabus, this is relevant for the second module: The Acidic Environment; and relates specifically to the following syllabus dot point:
Define Le Chatelier’s principle
Identify which factors can affect equilibrium in a reversible reaction
A worksheet on the addition and subtraction of decimals, up to 3 dp. There are 46 questions, 23 on addition and 23 on subtraction, decorated with a bit of Christmas fun.
Worked answers are included for every question.
Suitable for Stage 4 mathematics students (NSW).
Includes a 4 and a half minute teaching video on the addition and subtraction of decimals. (The link to the video is in the worksheet.)
This resource package covers learning the gradient, mid-point and distance between two points formulas. Appropriate for Stage 5. This pack contains:
An information sheets with formulas for gradient, mid-point and distance between two points, each with an example
A worksheet containing a series of coordinates on the Cartesian plane, asking students to find the gradient, mid-point and distance between two points
An activity sheet asking students to compare the length of two pathways using the distance formula
An activity sheet consisting of a matching game between coordinate pairs, gradients, distances and mid-points.
