Here is a collection of my Social Studies ready-to-print tests on Government. Each test comes with a printable study sheet (that I normally give to students to study for the test a week ahead) and an answer key.
Topics covered are: The federal government, The provincial government, The municipal government, Immigration, and Canadian symbols.
Since government can be a tricky unit for students, as there are a lot of abstract concepts and more complex vocabulary, I like to break it down into various sub-categories. To make sure that my students are on board, I like to check in on them from time to time with a test. The tests are designed not to be worth too much at a time- this way if the students don't do as well as they were hoping, they are not really penalized much.
