Today I have started this challenge where we had to put apostrophes over words. Since I have already changed everything, here is an example of one that I have done so far. Do not - Don't. As you can see there is a big difference with Do not and don't. Don't have an apostrophe because it is letting you know it is a shorter word for do not. Also it tells you that there is a missing letter, and it is "O". The hardest part about this activity is that we had to try and find out what the shorter word was for the big number.
