Rationale: This slide is about rounding decimals — a purely mathematical concept with no AU-specific spelling, terminology, units, currency, or cultural references. All content is universally applicable.

Rationale: AU spelling found: "Rationalising", "rationalised", and "Rationalise" need to be converted to US spellings "Rationalizing", "rationalized", and "Rationalize". No metric units, currency, or cultural references present.

Rationale: No AU-specific content found. The template covers trigonometric exact values for negative angles (sin, cos, tan of -60°) and trigonometric identities — pure math content identical in AU and US curricula. No AU spelling, terminology, units, or cultural references present.

Rationale: This slide contains pure mathematics content (exponential simplification using prime factors) with no AU-specific spelling, terminology, units, currency, or cultural references. All content is universal mathematical notation.

Rationale: No AU-specific content found. The slide teaches counting by unit fractions on a number line using purely mathematical content (fractions 1/2, 2/2, 3/2, 4/2). No AU spelling, terminology, units, currency, or cultural references present.

Rationale: No AU-specific content found. The text uses standard mathematical terminology (perpendicular bisector, right angle, line segment) with no AU spelling, currency, cultural references, or metric units. The images show geometric diagrams with no AU-specific labels.

Rationale: The template explicitly references Australia (map of Australia), Australian cities (Melbourne, Sydney), and Australian time zones. All content must be converted to US equivalents. Using New York and Boston (both Eastern Time) to preserve the "same time zone" answer logic.

Rationale: No AU-specific content found. All text uses standard mathematical terminology (horizontal line test, one-to-one, many-to-one) with no AU spelling, units, currency, or cultural references. The image shows generic math graphs with no AU-specific content.

Rationale: This slide is purely about adding fractions with different denominators. There is no AU-specific spelling, terminology, units, currency, or cultural references. All content is universal math notation.

Rationale: Template uses metric units (cm) throughout a geometry problem. The 6cm, 8cm, 10cm triangle sides need conversion to US customary. Converting to 6 in, 8 in, 10 in preserves the exact same mathematical relationships (3-4-5 ratio ×2), keeping cos(A) = 0.6 and the answer of 53.13° unchanged. This is a clean, pedagogically sound conversion.

Rationale: This slide teaches solving simultaneous equations using substitution. All content is pure mathematics with no AU-specific spelling, terminology, units, currency, or cultural references. "Maths" does not appear in any text field. No changes needed.

Rationale: No AU-specific spelling, terminology, currency, cultural references, or metric units found. The content is a straightforward math word problem using pencils and whole numbers with no AU-specific content.

Rationale: No editable text fields or images were provided in the input — only a skill ID string "xk3vzmJzOkW3w4xL2Qvl". There is no AU-specific content to evaluate or convert.

Rationale: This slide explicitly teaches the process of converting metric rate units (km/h → m/s) by breaking it into steps: converting kilometres to metres, converting hours to seconds, then writing the new rate. This is core metric unit conversion pedagogy, not a word problem that merely uses metric context. AU spelling: "kilometres" and "metres" should be updated to "kilometers" and "meters".

Rationale: No AU-specific content found. The slide teaches statistical concepts (outliers, IQR, quartiles) using universal mathematical terminology. No AU spelling, currency, cultural references, or metric units are present.

Rationale: All text fields contain general mathematical language about ratios with no AU-specific spelling, terminology, units, or cultural references. The image shows a ratio simplification diagram (5:15 → 1:3, dividing by 5) with no AU-specific content.

Rationale: No AU-specific content found. The template covers finding the turning point of a parabola — pure math with no AU spelling, terminology, units, currency, or cultural references. "Turning point" is used in both AU and US math contexts (US also uses "vertex," but "turning point" is not exclusively AU). No metric units present.

Rationale: No AU-specific content found. The slide covers basic counting/addition concepts (counting to 1000, carrying digits) with no AU spelling, terminology, units, currency, or cultural references.

Rationale: No AU-specific content found. The template covers basic subtraction with place value tables (Tens/Ones). No AU spelling, terminology, units, currency, or cultural references are present. The word "maths" does not appear; all text is standard math terminology applicable to both AU and US contexts.

Rationale: No AU-specific content found. No metric units, no AU spelling, no AU terminology, no currency, no cultural references. The scatterplot uses dimensionless data (hours studied vs. test scores) with universal statistical terminology (EV, RV). All content is already US-compatible.

Rationale: No AU-specific content found. The slide teaches counting by twos using a number line and colored blocks. No AU spelling, terminology, units, currency, or cultural references are present.

Rationale: No AU-specific content found. The template covers "Counting arrangements" — a purely mathematical concept with no AU spelling, terminology, units, currency, or cultural references. All text is universally applicable.

Rationale: AU spelling found: "coloured" appears twice (in text objects 669567149 and 1724638199243000). No metric units, no AU cultural references, no AU math terminology. Only spelling changes needed.

Rationale: No AU-specific content found. The slide covers geometry terminology (naming angles, vertex) with no AU spelling, units, currency, or cultural references. All content is universally applicable.

Rationale: The slide uses m² (square meters) for land area, a metric unit. The regression equation "House Price = 2.07 × Land Area - 14" has a coefficient (2.07) that is derived from the m² unit system. Converting to ft² would require re-deriving the coefficient (2.07 ÷ 10.764 ≈ 0.192), making this units_complex. Only AU spelling fixes apply (no spelling issues found here). The image also shows "Land Area (m²)" on the axis.

Rationale: No AU-specific content found. The text fields use standard mathematical/statistical terminology (correlation coefficient, scatterplot, direction, strength) with no AU spelling, units, currency, or cultural references. The image shows a generic statistics diagram with correlation coefficient scale and scatter plots — no AU-specific content.

Rationale: No AU-specific content found. The text uses universal math terminology, no AU spelling, no metric units, no cultural references. The currency symbol used is "$" which is universal in context. The image shows a ratio diagram (3:6 → 1:2 → 7:14) with no AU-specific content.

Rationale: This slide is about identifying cubic equations in algebra. There is no AU-specific spelling, terminology, units, currency, or cultural references. All content is pure mathematics with no localization needed.

Rationale: The image shows an Australian 20-cent coin (labeled "AUSTRALIA 2006" with Queen Elizabeth II on the reverse). This is AU-specific currency content that needs to be replaced with a US coin image. The text content itself is general probability/math content with no AU-specific terminology.

Rationale: No AU-specific spelling, terminology, units, currency, or cultural references found in any text fields or images. The content covers types of data (discrete, continuous, qualitative, quantitative) using universally neutral examples (books, balls, children, temperature, rain, horse speed). No metric units, AU spelling, or AU cultural content detected.

Rationale: No AU-specific content found. The slide teaches multiplication using apples as visual aids. All text is standard math terminology with no AU spelling, currency, units, or cultural references.

Rationale: The only AU-specific content is "maths" in the text field, which should be changed to "math" for US localization. No metric units, no cultural references, no AU-specific terminology beyond this spelling difference.

Rationale: No AU-specific content found. The template is a basic math counting exercise using numbers (counting by fives on a number line). No AU spelling, terminology, currency, cultural references, or metric units present.

Rationale: No AU-specific spelling, terminology, units, currency, or cultural references found in any text fields. The content is purely algebraic/mathematical with no metric units or AU-specific content. The image shows algebraic equations (4x - 7 = 2x + 5 and 4x - 2x = 5 + 7) with no AU-specific content.

Rationale: No AU-specific content found. All text is universal math terminology (exponential functions, growth, decay). No AU spelling, units, currency, or cultural references. Images show standard mathematical graphs with no AU-specific content.

Rationale: The images depict emus, which are iconic Australian animals not native to or commonly associated with the United States. The math content (10 x 2) and text are otherwise neutral with no AU spelling, terminology, or unit issues.

Rationale: The slide contains metric units (cm) in both text fields and the diagram image. However, the WARNING indicates formulas contain the same numbers as text fields and coefficients depend on the unit system, so this must be classified as units_complex. Only AU spelling fixes apply (cm labels remain, no numeric conversion). No AU spelling differences exist beyond the unit labels themselves.

Rationale: No AU-specific content found. The slide uses USD ($) currency already, no AU spelling, no AU terminology, no metric units, no cultural references. All content is universally applicable.

Rationale: AU spelling found: "Modelling" should be "Modeling". The cm unit is a label in a pure math/trig context where the amplitude (3) is a clean pedagogical number; converting to inches would yield 1.18 in, which is not pedagogically clean and the formula is a defined mathematical model. No other AU-specific content found.

Rationale: No AU-specific content found. The template teaches fractions using stars as visual examples. No AU spelling, terminology, units, currency, or cultural references are present. Content is universally applicable.

Rationale: This slide explicitly teaches metric units of area (cm², m², ha, km²) and their appropriate use cases. It is a metric unit reference/vocabulary slide. AU spelling found: "centimetres" and "metres" need fixing to "centimeters" and "meters". All metric units and values are preserved.

Rationale: No AU-specific spelling, terminology, units, currency, or cultural references found in any text fields. The content is a simple early-years math word problem about balloons using universal English.

Rationale: The term "brackets" is AU/UK terminology; US math education uses "parentheses." No metric units, currency, or cultural references present. This is a terminology-only change.

Rationale: No AU-specific content found. All text fields contain universal mathematical terminology about logarithms with no AU spelling, units, currency, or cultural references.

Rationale: No AU-specific content found. The template discusses transport timetables with generic station names and times. No AU spelling, terminology, currency, units, or cultural references are present.
