30 teaching weeks · 4 cycles · school weeks 4–33
Welcome, Standard 5! Standard 5 is the bridge year — it takes what you learned in
Standard 4 and gets you ready for Standard 6. Everything you need is here: your weekly lessons,
your daily Power-Ups, every graded assessment, and the tools you can reach for whenever you get stuck.
How the year is built. School weeks 1–3 are the Diagnostic and Repair block.
Teaching runs from week 4 to week 33 across four cycles — 150 lessons in all. Weeks 34–36 are
buffer for national assessments and school activities. Each card below opens one teaching week.

Five questions. Ten minutes. Every day. Five minutes working on your own, then five
minutes reviewing together. Power-Ups are practice only — they are never graded and never
homework. Their job is to keep everything you have learned within reach.

Reach for these whenever you need them. Nothing here is graded and nothing is timed.
Some are reference tools you check mid-problem; others are simulations you play with until the idea clicks.
Use them in class, at home, or while revising for a test.
Reference tools · check these mid-problem
Place Value Chart
Millions down to ten-thousandths. Type any number and see every digit land in its column — the tool behind scientific notation, rounding and decimal comparison
Fraction, Decimal & Percent Wall
Compare fractions by sight, find equivalents, and read the same amount three ways. Backs everything in Cycle 2 from mixed numbers to percentage change
Formula & Unit Card
Every Standard 5 formula in one place — perimeter, area, circumference, volume, surface area, speed — with a unit converter beside it
Maths Word Bank
Every vocabulary term from the year's anchor strips, explained in plain language with one worked example each
Simulations · play until the idea clicks
Pi Discovery Lab
Measure the circumference and diameter of circle after circle, record the ratio, and watch every answer settle near the same number — π before it is ever given to you
Net Folding Lab
Fold a flat net into a solid and unfold it again. Test which nets actually close, then compare the surface area you can see with the volume you cannot
Coordinate Reflection Grid
Plot a shape, reflect it in the x-axis or y-axis, and read what happens to each coordinate. Then build a tessellation from the result
Probability Simulator
Roll, spin or draw a hundred times, a thousand times, ten thousand times — and watch the experimental result close in on the theoretical one
Graph Builder
Enter your own data and build a bar graph, line graph or circle graph from it — then see which graph tells the story best
Factor Tree Builder
Break any number down branch by branch until only primes are left, then use the result to find the LCM and GCF of a pair
