Math Live is an amazing website for mathematics teacher. It is produced by the Ministry of Education of Alberta.
When you start Math Live, there is an intro video presenting the four characters. It is possible to skip this intro and go directly to the lessons and the glossary.
Lessons are available in the four main strands of mathematics in Alberta : Number, Patterns and Relations, Shape and Space and Statistics and Probability.
Lessons include concepts such as place value, proper fractions, equivalent fractions, multiplication and divisions of decimals, patterns, area, perimeter, volume, polygons, tessellation, displaying data and probability.
The lessons are visually attractive and presented in a fun way by the characters.
All the lessons also include parent notes, teacher notes and assessments.
