reSolve: Authentic Problems: Target Ball

This sequence of four lessons explores the relationship between an informal unit of measure and what is being measured using the context of designing a game of 'Target Ball'. Students work in groups to collect data on how far their chosen ball rolls, using a cut-out foot as an informal unit of measure. They represent and interpret their data and then work towards using formal units to make their game 'fair'. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources. This sequence is part of the reSolve: Mathematics by Inquiry special topic 'Authentic Problems'.
