Interventions Book Resources

We are excited to announce that in 2016 the Interventions in Mathematics series was Highly Commended by the Educational Publishing Awards!

This series is designed to catch students up quickly in key number concepts, by using confronting questions to address misconceptions.  Our data from Partnership Projects during 2015-2016 shows effect sizes of between 0.49 and 0.75 in PAT Maths when the resources were used once per week for a period of eight months.

This page contains a number of resources from each book.  Please feel free to download them and try them out with your students.  The diagnostic tests are particularly important.
