While I am not a fan of timed math tests (understatement) there are still some good reasons to have review slides for math facts.
These slides scramble once a day, automatically. Bookmark the link to quickly display math facts to review. These are all the addition, subtraction, multiplication, and division facts with the digits 0 to 9.
Google Slides
I have created a few different versions. The button to the left is the actual slides that are not automatically presenting. The slides above auto advance every second.
