About the Author Lucy Patston BA BSc Hons PhD Lucy has 20 years of teaching experience and a strong academic background She has expertise in neuroscience psychology and human development and gained her doctorate for research investigating how childhood learning affects brain functioning in adulthood Lucy is a mum to three lovely children all of whom have recently entered the school system As a parent and a teacher she understands how important it is for students to grasp key mathematical concepts and for parents to be actively engaged in this process Lucy was raised in New Zealand during a time when the school curriculum was taught very differently to today so she understands how confusing it can be when children come home performing maths in the strangest ways In the Reaching Competency Programme Lucy spends an equal amount of time helping parents understand the curriculum as she does students She believes that if parents can communicate effectively with their children about the concepts they are currently learning in the classroom then children will not only feel supported in their learning but will be open to realising how important maths is in our everyday lives 25 2020 Adept Education Limited t a Reach Education
