manipulate formulas involving several variables using digital tools, and describe the effect of systematic variation in the values of the variables

How Bloomi helps with this

This is a NAPLAN-year topic. Bloomi teaches it with a short explainer, guided practice, and NAPLAN-style questions — every one traceable to this exact code.

What this looks like in the classroom

• experimenting with different sets of tables of values from formulas; for example, using volume of a rectangular prism = length × width × height, and specifying a fixed width and equal length and varying the height
• using spreadsheets and the formula function to recognise the effect of changing parameters on the entries in cells
• analysing distance travelled for different combinations of average speed and time of travel using a table of values and the distance formula
