Maths300 is a professional development platform. Its aim is to support teacher discussions around improving mathematics teaching and learning. Maths300 lessons are offered as fuel for that discussion.
Whole class investigations such as the one shown support teachers to model what it means to work like a mathematician. Maths300 provides hundreds of detailed, extensively trialled, lesson plans with this purpose.
 Teaching craft (pedagogy) is a focus of every lesson.
 About one half of the lessons are built on the iceberg information of our handson tasks.

 About one third of the lessons are extended by companion software.
 Free Sample Tour section includes three complete lessons with companion software.
