Explore the topics
Connect equal-sided arrays and square-root problems.
Use place-value powers and prime-power products.
Connect equivalent fractions, mixed numbers, decimals and signed positions.
Choose a suitable decimal accuracy and use estimates to check computations.
Use efficient fraction and decimal methods, then check digitally when useful.
Choose operations that match positive fractional and decimal quantities.
Find a percentage amount or express a part as a percentage of its whole.
Use signed numbers to compare positions and describe change.
Represent, simplify and use ratios without confusing a part with the whole.
Model a financial decision using rates, percentages and stated assumptions.
Translate quantities into symbols and substitute known values.
Apply number laws and write expressions with clear grouping.
Undo operations systematically and check natural-number solutions.
Investigate how one measured quantity changes with another.
Generate tables, find a rule and plot input-output pairs.
Use digital tables to investigate one variable at a time.
Relate rectangles, triangles and parallelograms through cutting and rearranging.
Calculate rectangular and triangular right-prism volumes.
Investigate the constant circle ratio represented by π.
Use corresponding, alternate and co-interior relationships with reasons.
Explain the triangle total and extend it to other plane polygons.
Connect a length ratio to the dimension of the measurement being compared.
Compare nets, plans, elevations and perspective representations.
Use side and angle tests and explain inclusive relationships.
Record translations, axis reflections and rotations about the origin.
Use ordered decisions and explain why the classification is consistent.
Calculate centre and spread and consider what each measure communicates.
Use dot plots and stem-and-leaf plots to discuss shape, centre, spread and extremes.
Use primary or secondary data to analyse a distribution and report a defensible finding.
List a complete single-stage sample space, assign probabilities and predict frequencies.
Run large digital simulations and explain differences using sample size.
