Key ideas
A perfect square is the area of a square with whole-number sides.
A ratio compares quantities and can have two or three terms.
Multiply numerators and multiply denominators.
The square root of a perfect square is the side length.
A part-to-part ratio can be rewritten as a part-to-whole fraction.
Watch out for
- Thinking the square root of 36 is 18 (half) instead of 6.
- Treating a ratio as a difference rather than a comparison.
- Thinking multiplying always makes a bigger number.

The official wording · 3 outcomes
- PR01
- graph and analyze two-variable linear relations
- PR02
- model and solve problems, concretely, pictorially, and symbolically, where a, b, and c are integers, using linear equations of the form ax = b; x/a = b, a ≠ 0; ax + b = c; x/a + b = c, a ≠ 0
- PR02
- using linear equations of the form ax = b; x/a = b, a ≠ 0; ax + b = c; x/a + b = c, a ≠ 0; a(x + b) = c
Key ideas
Substituting values for one variable finds the other.
A table of values becomes a set of points to graph.
The graph shows the relationship between the variables.
Isolate the variable using inverse operations.
Undo addition or subtraction before multiplication or division.
Watch out for
- Substituting into the wrong variable.
- Plotting points as (y, x) instead of (x, y).
- Undoing operations in the wrong order.

Measurement
The Pythagorean theorem and nets
Understanding the Pythagorean theorem
I can explain the Pythagorean theorem and test for a right triangle.
Official code: M01
Applying the Pythagorean theorem
I can find a missing side of a right triangle.
Official code: M01
Nets for 3-D objects
I can draw a net and match it to its 3-D object.
Official code: M02
Surface area and volume
Surface area of prisms
I can find the surface area of a prism.
Official code: M03
Surface area of cylinders
I can find the surface area of a cylinder.
Official code: M03
Volume of prisms and cylinders
I can find the volume of a prism or cylinder.
Official code: M04
The official wording · 6 outcomes
- M01
- develop and apply the Pythagorean theorem to solve problems
- M01
- develop and apply the Pythagorean theorem to solve problems
- M02
- draw and construct nets for 3-D objects
- M03
- determine the surface area of right rectangular prisms, right triangular prisms, and right cylinders to solve problems
- M03
- determine the surface area of right rectangular prisms, right triangular prisms, and right cylinders to solve problems
- M04
- develop and apply formulas for determining the volume of right rectangular prisms, right triangular prisms, and right cylinders
Key ideas
In a right triangle, a² + b² = c², where c is the hypotenuse.
Surface area is the total area of all faces.
The theorem applies only to right triangles.
Identify each face and find its area.
Squares built on the sides model the relationship.
Watch out for
- Applying the theorem to any triangle, not just right triangles.
- Missing a face when adding up the areas.
- Adding the sides instead of the squares of the sides.

Geometry
Views of 3-D objects
Top, front, and side views
I can draw and read the top, front, and side views of an object.
Official code: G01
The official wording · 1 outcomes
- G01
- draw and interpret top, front, and side views of 3-D objects composed of right rectangular prisms
Key ideas
Each view is a 2-D picture from one direction.
The three views together describe the 3-D object.
A rotation changes which view you see.
Watch out for
- Drawing a perspective picture instead of a flat view.
- Mixing up the front and side views.

Statistics and Probability
Critiquing data displays
Critiquing data presentation
I can critique how data is presented and spot misleading graphs.
Official code: SP01
The official wording · 1 outcomes
- SP01
- critique ways in which data is presented
Key ideas
Different graphs suit different data and have strengths and limits.
Formatting like interval size or a broken axis can mislead.
A conclusion should be consistent with the data.
Watch out for
- Trusting a graph's visual impression without checking the scale.
- Thinking any graph type fits any data set.
