See the idea. Put it to the test.

956 practicals from Kindergarten to Year 12, in 9 subjects. A practical gives the idea, what you need, the steps, what you should see and a safety card. A teacher-led practical gives the idea and its hazards; its method is for tutors on the learning platform.

Review

Reviewed before publication (owner’s confirmation, 24 September 2026). That covers every practical here, and a practical’s page lists the sources its author read.

A safety card on every page

The risk, who supervises and the hazards. The 38 teacher-led practicals show their idea and hazards here; their materials, steps and sources, and any result, control or note that states a number or an amount, are for tutors and administrators on the learning platform.

School laboratory, not for home

207 practicals are medium or high risk. Each says so on its page: In a school laboratory, with a teacher supervising, under the school's risk assessment. Not for home.

Curriculum references

Each practical lists the NSW syllabus outcomes and Australian Curriculum v9 codes it supports. They are references, not a verified or complete curriculum alignment.

Clear all

A practical is carried out at the bench, in the classroom or outdoors. A practical with its model not built stands on its own; the page says where a step mentions the model. A calculation and data practical works from published figures by hand, with a calculator or in a spreadsheet. No Lab page includes an interactive model; the Concept Studio holds the demonstrations.

  1. Mathematics K–6 · Kindergarten

    Which covers more: comparing areas by laying one shape on another

    Area is the amount of surface a shape covers, and two surfaces are compared by placing one on top of the other, not by how tall or wide they look.

  2. Mathematics K–6 · Years 1–2

    Covering a surface: area in rows and columns

    Area is measured by covering a surface with identical units that leave no gaps, and the units line up in rows and columns so the count can be found by rows times columns.

  3. Mathematics K–6 · Years 3–4

    Perimeter with string: the distance around a shape

    Perimeter is the length of the boundary of a shape, so a string laid around the edge and then measured straight gives the same length as adding the sides.

  4. Mathematics K–6 · Years 3–4

    Square centimetres and a square metre: covering with a grid

    Area is measured in square units of a fixed size, a square centimetre for small surfaces and a square metre for large ones, and 10 000 square centimetres fit in a square metre.

  5. Mathematics K–6 · Years 5–6

    Cut and rearrange: parallelograms and triangles from rectangles

    A parallelogram cut along its height and rearranged becomes a rectangle of the same area, and a rectangle cut along a diagonal gives two triangles of half its area.

  6. Mathematics K–6 · Years 5–6

    Length times width: where the area formula comes from

    A rectangle on a centimetre grid holds rows of equal squares, so its area is the number of squares in a row times the number of rows, which is length times width.

  7. Mathematics K–6 · Years 5–6

    Same fence, different paddocks: fixed perimeter, changing area

    Rectangles with the same perimeter can have very different areas, and the area is largest when the sides are closest to equal.
