Key ideas
A percent over 100% means more than one whole.
A unit rate lets us scale to any amount.
150% of an amount is one and a half times that amount.
We multiply the unit rate by the quantity we need.
A fractional percent such as 1/2% is less than 1%.
Watch out for
- Thinking a percent over 100 is impossible.
- Using the total instead of the unit rate.
- Capping a percent at 100.

The official wording · 5 outcomes
- 8.PR1
- Graph and analyse two-variable linear relations.
- 8.PR2
- Model and solve problems using linear equations of the form: • ; ax b = • , 0; x b a a = concretely, pictorially and symbolically, where a, b and c are integers.
- 8.PR2
- Model and solve problems using linear equations of the form: • ; ax b c + = concretely, pictorially and symbolically, where a, b and c are integers.
- 8.PR2
- Model and solve problems using linear equations of the form: • , 0; x b c a a + = concretely, pictorially and symbolically, where a, b and c are integers.
Key ideas
A two-variable linear relation graphs as a straight line.
We can read and interpret points on the line.
We undo addition or subtraction first, then multiplication or division.
We keep both sides balanced.
We undo the addition or subtraction first.
Watch out for
- Plotting coordinates in the wrong order.
- Joining points that should stay discrete.
- Undoing operations in the wrong order.

Shape and Space
Nets, Surface Area, and Volume
Nets for 3-D objects
I can draw and construct a net for a 3-D object.
Official code: 8.SS1
Surface area of rectangular prisms
I can find the surface area of a rectangular prism.
Official code: 8.SS2
Surface area of triangular prisms
I can find the surface area of a triangular prism.
Official code: 8.SS2
Surface area of cylinders
I can find the surface area of a cylinder.
Official code: 8.SS2
Volume of right prisms
I can find the volume of a right prism.
Official code: 8.SS3
Volume of right cylinders
I can find the volume of a right cylinder.
Official code: 8.SS3
The official wording · 6 outcomes
- 8.SS1
- Draw and construct nets for 3D objects.
- 8.SS2
- Determine the surface area of: • right rectangular prisms;
- 8.SS2
- • right triangular prisms;
- 8.SS2
- • right cylinders to solve problems.
- 8.SS3
- Develop and apply formulas for determining the volume of right prisms and right cylinders.
- 8.SS3
- Develop and apply formulas for determining the volume of right prisms and right cylinders.
Key ideas
A net is a flat pattern that folds into a solid.
Every face of the solid appears once in the net.
Surface area is the total area of all faces.
A rectangular prism has three pairs of matching faces.
A triangular prism has two triangular faces and three rectangular faces.
Watch out for
- Missing a face in the net.
- Overlapping faces so the net cannot fold.
- Finding volume instead of surface area.

Unit 4 · 2 skills
Statistics and Probability
Data Displays and Probability
Critiquing data displays
I can critique the way a set of data is presented.
Official code: 8.SP1
Probability of independent events
I can find the probability of two independent events.
Official code: 8.SP2
The official wording · 2 outcomes
- 8.SP1
- Critique ways in which data is presented.
- 8.SP2
- Solve problems involving the probability of independent events.
Key ideas
A display can mislead through its scale, spacing, or choice of graph.
A fair display lets the data speak for itself.
Two events are independent when one does not affect the other.
We multiply their probabilities to find the combined probability.
Watch out for
- Trusting a graph without checking the scale.
- Thinking any graph is neutral.
- Adding the probabilities instead of multiplying.
