Exam scope and assessment notes
Original teaching foundations for the 2026–2028 syllabus. Six prescribed texts have passage-specific sequences; all 693 printed vocabulary rows have been reconciled into 692 distinct records, with additional number, comparison and compound-verb practice. Linked teaching and lexical self-checks do not certify mastery. Complete line-by-line annotation, further translation and scansion practice, qualified Latin-teacher review, full timed papers and human marking remain outstanding. Open the assigned edition alongside these lessons: public ancient texts can differ in spelling, punctuation or editorial readings from the prescribed prose anthology. Practice explanations are formative, not Cambridge questions, marks or predicted grades. Cambridge has announced withdrawal; the last assessment is June 2028, in administrative zones 3, 4, 5 and 6 only. Confirm entry with your centre.
Before you begin
- Identify noun, verb and clause roles
- Recall the whole dictionary record rather than only its first spelling
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
What does a dictionary meaning fail to establish on its own?
What you will learn
- Recognise every required cardinal value
- Apply additive/subtractive construction and basic number agreement
Read the form, recall the meaning, then check the construction
Use the reference list to learn, then hide the meanings in recall practice. The usage note explains a grammatical clue or limit. Self-check labels do not award a grade or certify mastery.

centumCardinal numeral
100
A dictionary numeral label identifies the value. Unus, duo and tres and their relevant compound parts can require agreement; read the full noun phrase.
quingenti, -ae, -aCardinal numeral
500
An agreeing plural adjective: quingenti, quingentae, quingenta vary with the counted noun.
milleCardinal numeral
1000
Mille is normally indeclinable with a counted noun. Plural milia is a different noun construction and commonly uses a partitive genitive.
Build and check the values
The reference set includes every number from 1 to 100 and the additional 500 and 1000. Eleven to seventeen have particular forms such as undecim, quindecim and septendecim. Eighteen and nineteen commonly use two or one below twenty; the same subtractive method can form endings in eight and nine before the next ten.
The cards choose one conventional form without making other attested orders or additive forms wrong. For 21, viginti unus and unus et viginti illustrate alternatives. For 38, duodequadraginta is two below forty, not two plus forty. Read the parts arithmetically before translating.
Value is not the whole noun phrase
Unus, duo and tres have inflected forms; quingenti is an agreeing plural adjective. Mille is normally indeclinable with a counted noun, while plural milia is a neuter noun commonly followed by a partitive genitive. Consult full agreement and construction rather than use a dictionary label unchanged everywhere.
Distinguish a cardinal count from an ordinal position. The supplied cards identify values; they do not prescribe one rigid word order for every sentence or substitute for reading the noun's case.

Worked example
Calculate and interpret duodequadraginta.
Show the worked solution
- Quadraginta is forty.
- Duode signals two below the following ten.
- Subtract two from forty.
Answer Duodequadraginta is 38, because 40 − 2 = 38. It does not mean 42; a subtractive name must preserve the direction of the calculation.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Calculate undeviginti and duodeviginti.
Give me a hint
Subtract one or two from twenty.
Compare my reasoning
- Viginti is twenty.
- Unde gives twenty minus one.
- Duode gives twenty minus two.
The values are 19 and 18 respectively. The construction is subtractive and should not be reversed into twenty-one or twenty-two.
Look for these in your work
- Uses base
- Subtracts one
- Subtracts two
Independent: Read nonaginta tres and duodecentum.
Give me a hint
One adds to ninety; one subtracts from one hundred.
Compare my reasoning
- Ninety plus three gives the first.
- One hundred minus two gives the second.
- State both values.
Nonaginta tres is 93 and duodecentum is 98. The differing constructions must be calculated separately rather than treated as one identical order of units and tens.
Look for these in your work
- Uses addition
- Uses subtraction
- Gives both values
Application: A learner rejects unus et viginti because the card shows viginti unus. Explain the limitation of the card.
Give me a hint
A chosen reference spelling is not every valid expression.
Compare my reasoning
- Both express twenty-one.
- Alternative attested order is allowed.
- Agreement and context still need checking.
The card gives one conventional reference form, not a rule rejecting every alternate order. Unus et viginti can express the same value; its actual noun phrase still needs appropriate agreement and construction.
Look for these in your work
- Uses equal value
- Allows alternative
- Preserves grammar
Common mistakes
- Adding a subtractive number
- Rejecting every alternate order
- Using ordinal forms for a count
