Mathematical Precision
Communicate with mathematical precision: use correct fraction/decimal vocabulary, name angle types accurately, specify units in measurement and money, and use notation (=, <, >, ÷, ×) correctly
What a learner can do afterwards
- Distinguish between 'three fourths' and 'three quarters' and use both correctly
- State an answer in the correct unit: '63 square centimetres' not just '63'
- Write 15:45 in 24-hour notation and explain the distinction from 3:45 pm

In maths, some words and symbols only work if you get them exactly right. Saying '3/4' as 'three fourths' or 'three quarters' tells people exactly what you mean. Saying 'sort of half' does not.
Mia's sticker costs two pounds and fifty pence. She writes the price as £2.50, not 2.5 or 250. The £ sign and two decimal places show the exact amount.
A digital clock shows time two ways. The 12-hour clock uses 'am' for morning and 'pm' for afternoon. The 24-hour clock keeps counting past 12. From 1:00 pm to 11:59 pm, add 12 to the hour. So 3:45 pm becomes 15:45. At noon, 12:00 pm is 12:00. At midnight, 12:00 am is 00:00. The 24-hour version never needs 'am' or 'pm'.
When you write a maths answer, always include the unit, like 63 square centimetres, and use the exact symbol you mean: = for equal, < for less than, > for greater than, ÷ for divide, and × for multiply.
Precise maths means using exact fraction words, the correct unit, and the right time notation, every time.
