  "annual_limit": "This ten-day written proposal contributes selected evidence opportunities. It is not an accepted Source, annual completion, whole folio, calibrated task-specific A–E guide, curriculum certification or proof a learner is ready for the next year. Other state/territory syllabus requirements must be checked independently; no NSW/Victoria/other-state mapping is claimed.",

  "criteria_bridge": "The four local criteria—Formulate, Solve, Check, Interpret—support these proficiencies. Evidence and help are recorded separately. QCAA annual on-balance judgement and task-specific guides remain the educator's responsibility.",
  "familiarity": "Do not call a new numeral an unfamiliar task. Record actual prior exposure, materials, hints and context. Adjusting steps, scaffolds and constraints can change complexity; changing a context may change familiarity, but only an actual learner observation can establish that.

## All23full descriptions and exact partial opportunities

### AC9M4N01 · Open in this block

recognise and extend the application of place value to tenths and hundredths and use the conventions of decimal notation to name and represent decimals

AuthorityID:acara-v9:learning_areas:AC9M4N01; originalrow17541.

Prices are whole dollars only. No tenths/hundredths representation or cents evidence is claimed.

### AC9M4N02 · No new instruction claimed

explain and use the properties of odd and even numbers

AuthorityID:acara-v9:learning_areas:AC9M4N02; originalrow17548.

Earlier reviewed odd/even opportunities remain historical. These equal groups do not by themselves assess explanation of odd/even properties.

### AC9M4N03 · Open

find equivalent representations of fractions using related denominators and make connections between fractions and decimal notation

AuthorityID:acara-v9:learning_areas:AC9M4N03; originalrow17553.

No equivalent fraction/decimal task; equal groups are not automatic fraction equivalence evidence.

### AC9M4N04 · Open

count by fractions including mixed numerals; locate and represent these fractions as numbers on number lines

AuthorityID:acara-v9:learning_areas:AC9M4N04; originalrow17559.

No fraction counting or number-line teaching.

### AC9M4N05 · Supporting connection only; full description open

solve problems involving multiplying or dividing natural numbers by multiples and powers of 10 without a calculator, using the multiplicative relationship between the place value of digits

AuthorityID:acara-v9:learning_areas:AC9M4N05; originalrow17564.

Day64 partitions into tens and ones. It does not establish the required multiplicative place-value reasoning for multiples/powers of10 and calculator-free division.

### AC9M4N06 · Selected partial opportunities

develop efficient strategies and use appropriate digital tools for solving problems involving addition and subtraction, and multiplication and division where there is no remainder

AuthorityID:acara-v9:learning_areas:AC9M4N06; originalrow17568.

Days61–65/68–70 use multiplication, exact division, addition/subtraction and efficient strategies. All division examples have no remainder. Digital models/calculator checks are optional where appropriate, not evidence of independent mental reasoning. No claim every four-operation demand is mastered.

### AC9M4N07 · Selected financial opportunities

choose and use estimation and rounding to check and explain the reasonableness of calculations including the results of financial transactions

AuthorityID:acara-v9:learning_areas:AC9M4N07; originalrow17576.

Day67, H07/X07, C13–14 and V06A–D/N21–24 explicitly explain upper rounding versus an exact close-budget decision. Day70 includes a reasonableness check. Whole-dollar fictional costs only; broader contexts remain for later revisits.

### AC9M4N08 · Main practical-modelling opportunity

use mathematical modelling to solve practical problems involving additive and multiplicative situations including financial contexts; formulate the problems using number sentences and choose efficient calculation strategies, using digital tools where appropriate; interpret and communicate solutions in terms of the situation

AuthorityID:acara-v9:learning_areas:AC9M4N08; originalrow17580.

Days61–70/30routes model additive and multiplicative situations: total/groups/pergroup, one-off costs, financial constraints and useful decisions. Criteria require known/unknown roles, number sentence, efficient strategy and contextual meaning. A future reviewed PlanBench is a manual digital aid, not a solver or automatic achievement claim.

### AC9M4N09 · Open

follow and create algorithms involving a sequence of steps and decisions that use addition or multiplication to generate sets of numbers; identify and describe any emerging patterns

AuthorityID:acara-v9:learning_areas:AC9M4N09; originalrow17586.

The modelling routine is not a taught number-generating decision algorithm; no emerging-pattern evidence claimed.

### AC9M4A01 · Prior partial opportunity retained; no new full-code claim

find unknown values in numerical equations involving addition and subtraction, using the properties of numbers and operations

AuthorityID:acara-v9:learning_areas:AC9M4A01; originalrow17591.

Published11–12 teaches unknown additive roles. Budget subtraction/inverse checks here do not replace explicit unknown-equation instruction and assessment.

### AC9M4A02 · Selected calculator-free strategy opportunity; complete proficiency open

recall and demonstrate proficiency with multiplication facts up to 10 x 10 and related division facts; extend and apply facts to develop efficient mental strategies for computation with larger numbers without a calculator

AuthorityID:acara-v9:learning_areas:AC9M4A02; originalrow17596.

Day64 and V04A–D/N13–16 extend useful facts to larger whole-number products with explanation before calculator checks. Exact divisions use related facts. No full recall/proficiency span through10×10 or speed test has been completed.

### AC9M4M01 · Open

interpret unmarked and partial units when measuring and comparing attributes of length, mass, capacity, duration and temperature, using scaled and digital instruments and appropriate units

AuthorityID:acara-v9:learning_areas:AC9M4M01; originalrow17604.

Imaginary capacities/prices do not teach scaled instruments, partial units or physical measurement.

### AC9M4M02 · Open

recognise ways of measuring and approximating the perimeter and area of shapes and enclosed spaces, using appropriate formal and informal units

AuthorityID:acara-v9:learning_areas:AC9M4M02; originalrow17612.

Array pictures support multiplication; they are not an area/perimeter unit or formal measurement assessment.

### AC9M4M03 · Open

solve problems involving the duration of time including situations involving “am” and “pm” and conversions between units of time

AuthorityID:acara-v9:learning_areas:AC9M4M03; originalrow17618.

Suggested lesson times are teacher planning, not duration/am/pm/conversion problems.

### AC9M4M04 · Open

estimate and compare angles using angle names including acute, obtuse, straight angle, reflex and revolution, and recognise their relationship to a right angle

AuthorityID:acara-v9:learning_areas:AC9M4M04; originalrow17622.

No angle-name or right-angle comparison instruction.

### AC9M4SP01 · Open

represent and approximate composite shapes and objects in the environment, using combinations of familiar shapes and objects

AuthorityID:acara-v9:learning_areas:AC9M4SP01; originalrow17628.

Schematic kit/vehicle drawings are not a taught composite-shape approximation task.

### AC9M4SP02 · Open

create and interpret grid reference systems using grid references and directions to locate and describe positions and pathways

AuthorityID:acara-v9:learning_areas:AC9M4SP02; originalrow17633.

Group labels/destination lists are not a grid-reference/direction lesson.

### AC9M4SP03 · Open

recognise line and rotational symmetry of shapes and create symmetrical patterns and pictures, using dynamic geometric software where appropriate

AuthorityID:acara-v9:learning_areas:AC9M4SP03; originalrow17639.

Repeated arrays do not establish line/rotational-symmetry explanation.

### AC9M4ST01 · Open

acquire data for categorical and discrete numerical variables to address a question of interest or purpose, using digital tools; represent data using many-to-one pictographs, column graphs and other displays or visualisations; interpret and discuss the information that has been created

AuthorityID:acara-v9:learning_areas:AC9M4ST01; originalrow17645.

Cost comparison tables are not collected statistical variables or many-to-one displays.

### AC9M4ST02 · Open

analyse the effectiveness of different displays or visualisations in illustrating and comparing data distributions, then discuss the shape of distributions and the variation in the data

AuthorityID:acara-v9:learning_areas:AC9M4ST02; originalrow17652.

Comparing two purchase plans does not assess distribution shape/variation or display effectiveness.

### AC9M4ST03 · Open

conduct statistical investigations, collecting data through survey responses and other methods; record and display data using digital tools; interpret the data and communicate the results

AuthorityID:acara-v9:learning_areas:AC9M4ST03; originalrow17657.

No survey/statistical investigation, student-data collection or fabricated local survey.

### AC9M4P01 · Open

describe possible everyday events and the possible outcomes of chance experiments and order outcomes or events based on their likelihood of occurring; identify independent or dependent events

AuthorityID:acara-v9:learning_areas:AC9M4P01; originalrow17662.

No likelihood or event independence/dependence teaching.

### AC9M4P02 · Open

conduct repeated chance experiments to observe relationships between outcomes; identify and describe the variation in results

AuthorityID:acara-v9:learning_areas:AC9M4P02; originalrow17671.

No repeated chance experiment or observed variation.
