In 2017, I launched Lynz Education to provide numeracy consultancy support to schools and teachers in Australia. I want to stop the struggle and anxiety in primary maths classrooms by teaching teachers what works, so students can 'get' maths and leave school numerate.  I have focused my 30+ year education career on helping students to have a positive experience of learning. 

I have taken my research and made it practical for teachers and parents. I'm sharing it in short, easy-to-access, easy-to-apply online courses.  The list of courses will continue to grow over time.  You may even request a topic if you like.  Check out our Online Learning section. 


I've also blended my research and experience into teaching resources for classroom use. All students can participate in these activities and with careful questioning, you can extend every student’s maths thinking!  Check out my PowerPoint resources for classroom use.  


As we know, not all students 'get' Maths easily.  One of the reasons for that is that they have not had the opportunity to gain the number sense they need and the mathematical language understanding that develops in parallel with it.  I've been researching and trialling number sense interventions for over a decade, and I've developed a one-to-one intensive support program for students that can be individualised to meet the starting point of the students you are working with.  Check out the LINDA (Lynz Intervention Numeracy Drill Activities) program in our Lynz Education Resources.

2021 - Present

University of Newcastle

Currently, I'm completing my PhD research on developing and assessing the efficacy of a Tier 3 number sense intervention for students at risk of mathematical failure in the early years of school. 

2009 - 2011

University of Sydney

I completed a Masters by research on the efficacy of the Number Worlds program to improve the number sense of students in Kindergarten as a Tier 3 intervention. 


University of Melbourne

I added a Graduate Diploma in Special Education to my primary teacher training so that I could be prepared with strategies that would work to help all students learn.

I am delighted to write a testimonial on behalf of Lynelle Campbell and her work with staff and students at my school. At all times I have found Lynelle to be extremely professional, thorough and dedicated. Lynelle is an expert in her field and has the ability to easily communicate and share her knowledge with staff.

Lynelle’s ongoing consultancy made a positive difference to our staff in how to assess and monitor student’s growth and development in number sense.

Lynelle’s expertise in this area made an enormous difference to my staff in their understanding of student needs and the explicit teaching of number sense significantly contributed to students’ improved results in mathematics. I am very much looking forward to Lynelle providing consultancy support to the staff at my new school.
