This collection of Level 1 resources from Nuffield Mathematics covers Using data. The demand is roughly equivalent to that in Foundation Level GCSE and Level 1 Functional Mathematics. 

This resource provides a lesson in which children understand and use negative numbers in the context of
temperatures. Looking at the temperatures of different cities, they find missing temperatures and temperature differences. Temperature scales are provided which could help children who need a visual...

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of how students use graphs mathematically, from reading information from a graph to using graphs to show distance, velocity and acceleration.

Using graphs pack one...
