Create and follow algorithms that generate number sets, and identify and explain patterns that emerge from those algorithmic rules.

Identify and use relationships between angles on a straight line, at a point and vertically opposite angles to find unknown angles.

Understand area as square units, derive and apply the formula for the area of a rectangle, and solve real-world area problems.

Conduct repeated chance experiments and digital simulations, compare observed results with expected outcomes, and understand how variation changes with more trials.

Understand decimal place value to thousandths and add and subtract decimals with different numbers of decimal places, applying place value alignment strategies.

Divide decimals by whole numbers using place value strategies and long division, and use estimation and properties to check the reasonableness of products and quotients.

Apply the order of operations with brackets and use inverse operations and number properties to find unknown values in one- and two-step equations.
