In addition to the resources below, be sure to check out the Guides to Effective Instruction listed under Teacher Resources. These will provide you with even more number sense activities which are aligned with Ontario curriculum expectations. Also, don’t forget about the Gap-Closing Resources to help make concepts clear for struggling students. Here’s an example of a Gap-Closing Student Book (Marian Small, 2010) about Comparing and Ordering Whole Numbers to 100 000 .

And…you must check out the CLIPS and ePractice activities for Fractions (oame.on.ca)

In addition, visit my Videos for Teachers links to find eWorkshop.ca videos, created by the Ontario Ministry of Education, to assist with pedagogy and instruction. There are eight modules in total. Each module contains several videos featuring a teacher in action before, during and after the lesson (a three-part lesson). You can easily access them all here.
