I went through all the published sections of the Grade 3 EQAO tests for three years (2010 - 2013), to find the 'math facts'. These are facts that need to be known before a question can be answered, such as the number of hours in a day.
This multiple choice quiz includes ALL of these math facts from these three years' tests.
It's a quick quiz, simple to administer, but contains crucial facts that students need to know.
The .zip file contains versions in Microsoft Word (a very old version!) and pdf.
