Three 'measuring' work stations set up (one for each continuous variable: height, hand span and arm length) with space and materials for 3 groups of 3-4 around each station. Each pupil is to be given a personal data slip that they must complete whilst working in groups of 3-4. | |||
The data slip could be something simple like this: | |||

Groups circulate through all three stations helping each other to make accurate measurements. | ||
Data could be collected in one lesson and analysed in a further lesson. This gives the teacher time to set up the range fields on the spreadsheet based on the data collected. | Data could be collected in one lesson and analysed in a further lesson.

Extension/enrichment activities: Hand span measurement could be used to measure arm length/hand (see professional development PDF below) could be drawn around on square paper and the area worked out and compared with HS to look for patterns/data could be analysed by sex, age, to look for patterns also pattern spotting between variables. | Extension/enrichment activities: Hand span measurement could be used to measure arm length/hand (see professional development PDF below) could be drawn around on square paper and the area worked out and compared with HS to look for patterns/data could be analysed by sex, age, to look for patterns also pattern spotting between variables. | ||
