In this ‘Ask the expert’, Emily Jones explores the ways in which year 1 pupils recognise the value of British coins, using a question from NFER’s year 1 maths assessments.
Whatever the age of the pupil, studying the strategies used to answer questions can be immensely informative. It is for this reason that at NFER we have produced diagnostic guidance for our new spring term reading and mathematics assessments for years 1 and 2, following the analysis of answers given in a nationally representative trial of the assessments. We wanted to produce meaningful information for teachers of younger pupils, in line with what we provide for year 3-5 teachers in the spring term and, more recently, year 6 teachers in both autumn and spring. Incorporated into our teacher guides, this diagnostic commentary helps teachers to identify common errors and offers next steps advice to inform future teaching.
The example below was trialled during the development of our year 1 spring mathematics assessments, and can be found within our sample materials. With the help of visual aids, pupils are assessed on their ability to recognise the value of coins in the UK.
What did pupils do?
Perhaps unsurprisingly, three of the options made up over 95% of pupil responses: 2p, 20p and £1 – the correct answer.
What do the results tell us?
Including the 2p coin as an option in this question tested the misconception that a coin’s physical size determines its value. In total, 12% of pupils made this mistake. Another pitfall for pupils was the assumption that the value of a coin is specified only by the number on its face; in this example, 20p would have the highest value by this logic. Close to half of the pupils sampled (45%) made this mistake. Slightly fewer pupils correctly chose £1 (39%).
What does this mean for teaching?
More than half of the pupils sampled chose an incorrect answer to this question, demonstrating that misconceptions about the value of British coins are common in key stage 1. It indicates that pupils need opportunities to explore and understand the difference between pounds and pence. Although not specified in the national curriculum, some pupils may be aided by an awareness that 100 pennies have the same value as 1 pound.
Alternatively, pupils could research and compare items they could buy for 10 pennies vs. 10 pounds. Appreciating that a ticket to see a movie at the cinema (£10) is worth more than one play of a game at the school fete (10p) can help pupils distinguish between the two monetary units. Pupils can also work with sets of coins, ordering them according to size and according to value to understand that these orders differ.
