Read, write and compare decimals in scientific notation

This objective is an example of level 1. The highest demand for students to successfully meet this expectation requires them to use recall and use a routine method to convert a decimal to scientific notation.

Compute with numbers (that is, add, subtract, multiply, divide)

This objective requires students to conduct basic calculations. This is level 1 because it involves routine processing and involves a one step process.

Construct two-dimensional patterns for three-dimensional models, such as cylinders and cones.

This objective is an example of level 2. Although recognizing and drawing a two-dimensional pattern or a regular cylinder is expected to be routine (level 1), building a three-dimensional model would not be as routine. It would require at least two steps: first recognizing the shape, second drawing a two-dimensional object to reflect the shape in three-dimensions.

Grade 8: Solve two-step linear equations and inequalities in one variable over the rational numbers, interpret the solution or solutions in the context from which they arose, and verify the reasonableness of results.

This objective is an example of level 3. The expectation expressed in this objective is that students will not only solve a two-step linear equation, but will also interpret the solution and verify the results. This will require students to do some reasoning in order to interpret the solution and could be fairly complex depending on the context. If students were only required to solve linear equations and verify solutions, then the expectation would be level 2
