What is tables challenge? Well you get a sheet and it has a lot of times tables on it there are 50. So here is what happens you have three minutes to complete the test no more than that. Then you mark it. If you get 50 out of 50 you move up to the next level if you got 49 or lower you do the same test again the next day.
After you finish the test you write down your score in your graph here is my graph so far I am on level D.
