Misleading Graphs in the Media
DCF: Data and computational thinking → Data and information literacy
Pupils examine five invented graphs from a newsletter, an advert, a club report, an online poll and a governors' report, name the trick in each and spot the one that is fair. They measure the false impression in numbers, from percentage points against percentage change to area scale factors and a pie chart that adds up to 120%, redraw a truncated bar chart honestly and write a five-question checklist for any graph they meet online.
Resources required
- Pupil worksheet: Misleading Graphs in the Media
- Stimulus: five graphs, five headlines (print in colour if possible)
- Calculators, rulers and protractors

Reading a Spanish Survey on Teenage Free Time
DCF: Data and computational thinking → Data and information literacy
GCSE Spanish Unit 4 Reading and Writing (Areas of content, page 18): numbers, fractions and graphs in Spanish texts. Pupils read an invented survey of 300 young people by the youth centre in Montealbar, a Spanish town: a magazine article with six claims, a bar chart and three tables of hours per week, counts by age group and a one-week diary. They turn phrases such as dos de cada tres and diecinueve de cada veinte into fractions and percentages, compare age groups, and use mean, median and range on two diary groups, one with a 38-hour outlier. They test the six claims (two are not supported), explain why the chart's axis misleads, and write two English sentences on the trend and two Spanish sentences with their own figures and opinion.
Resources required

Fitness Apps and Body Image
DCF: Citizenship → Health and well-being
Pupils judge six invented fitness app screens by what each one really counts or rewards and whether its message is about how a body looks or what it can do, backing every verdict with an accurate fact about activity, rest or edited images. They rewrite three harmful notifications, choose safe default settings for a 15-year-old's account, and write a kind reply to a worried friend that names a trusted adult and a helpline. Pupils never measure or describe their own bodies.

Modelling Heart Rate Training Zones
DCF: Data and computational thinking → Problem-solving and modelling
GCSE Physical Education and Health Unit 1, section 1.2.4 Energy systems and training zones. Pupils take apart an invented running coach's spreadsheet model that turns age into aerobic and anaerobic training zones: they name its inputs, processes and outputs, find and fix four formula errors, run the model for two new athletes, and use it to judge five heart rate watch sessions, naming the zone and the predominant energy system. They then write and boundary-test an IF rule that names the zone, and explain why a 5-second sprint fools the model.
Resources required
- Pupil worksheet: Modelling Heart Rate Training Zones
- Stimulus: Afon Harriers training zones model pack (fact cards, spreadsheet and session data)
- Worked example and answer key: the four errors, zone and energy system for every session, the tested rule

Think Before You Share: Photos and Consent
DCF: Citizenship → Identity, image and reputation
Pupils decide what should happen to eight photos, from a group selfie to an image passed round a group chat, naming whose consent matters and what could go wrong. They find the hidden clues in a first-day selfie, including the location stored in the file, write a consent request and a take-down request, check four facts about the law, and build a five-question checklist to use before posting. No images or devices are used.

Religion in Wales: Reading the Census

Using real census figures for Wales and Rhondda Cynon Taf from 2001, 2011 and 2021, pupils group six smaller religions, calculate percentages, compare percentage point and percentage change, and draw percentage bars. They test four invented social media posts against the figures, name what the census cannot measure, and write a careful paragraph linking the trend to same-sex marriage and no-fault divorce without claiming cause. Background knowledge only, not NEA work.
