In this course, you will work on four math strands: Number (number concepts and number operations), Patterns and Relations (patterns and relationships and variables and equations), Time and Space (distance and currency), and Statistics and Probability (collecting and analyzing information). You will work through a variety of lessons based on six themes:



  • Understanding Numbers
  • Patterns and Relationships
  • Metric and Imperial Measurement
  • Everyday Measurement
  • Time and Space
  • Using Data


  • There is no textbook required for the course, and you will work both online and with your teacher to complete the lessons and activities that are a part of each theme. There will also be opportunities for you to think about and show what you've learned.

  • Materials that you will require for this course include a calculator, a ruler, a protractor, and scissors. (If you don't have these or other materials, please check with your teacher.)


  • There is a pop-up dictionary you can use throughout the course. Double click on any word and you will be taken to the definition for it.

  • There is also a glossary for this course. You will notice that important words have been highlighted in orange. When you put your cursor over any of these words and click on it, you will be able to read a definition for the word. 

  • You also have access to the content of the links at the top of this page. For more information on Content, Resources, Communication, Assessments, and My Teacher, please click here to watch the Moodle Videos. 

  • If you need technical support, please talk to your teacher.
