Welcome to GoFormative, Amanda! Iâ€™m a 7/8 Math teacher, myself, and have been using this app for the last several years. I donâ€™t want to remember teaching without it!
A few quick notes on the Formatives you posted:
Independent, Dependent, and Compound Events

I learned early on that, when teaching probability to 7thgrade minds, do not EVER use the phrases â€śget headsâ€ť or â€śget tailsâ€ť. You will be fending off snickers for far too long! I always substitute this with â€śthe coin lands on headsâ€ť or â€śthe coin lands on tailsâ€ť.

#6 doesnâ€™t specify what youâ€™re doing with the first black sock.

You have an image thatâ€™s embedded above question #7, then again inside the question. I might stick with one versus the other.

Also on #7, it looks like youâ€™re trying to find the compound independent probability of rolling a 3 and spinning an E, but your wording of â€śfind each probabilityâ€ť makes it sound like youâ€™re looking for each one separately.

GoFormative has the ability to format fractions inside of your answer options! You can either use the + button on the right, or just highlight the portion of the text that you want to turn into formatted math and choose â€śLatexâ€ť. When you do this on a fraction, like the answer choices in #15, it automatically formats it for you.

Try tagging math standards for each question so you and your math students can see their strengths and weaknesses for each standard. Find the little price tag icon in the lower left to explore this.
Pythagorean Theorem

I noticed that #5 and #7 are asking for the missing angle, but youâ€™re actually looking for a missing side length.

It looks like youâ€™re trying to account for studentsâ€™ possible answers, like in #4. However, if youâ€™re using a short answer type, as you are here, then you donâ€™t need to worry about accounting for spaces in your answers. If youâ€™re using the numeric type, you do need to worry about them, but not for short answers. It parses w=12 the same as w = 12 in short answer, but as different answers for numeric.

Each of the questions here is an introductory computation problem. This may be a deliberate choice on your partâ€¦ in which case, great! If not, you might want to throw in some word problems that make them compute multistep elements. As an example of these types of problems, take a look at the scavenger hunt that we have here: https://goformative.com/clone/WVVFZE
Complementary, Supplementary, and Adjacent

Whoops! Make sure you have an answer choice for #47.

I would highly recommend exploring the numeric answer type. You can enter the degree symbol there!

The phrasing â€ścomplementary angle 22 degreesâ€ť is a little weird. It makes more sense to me to hear â€śAn angle that is complementary to an angle measuring 22 degreesâ€ť. Itâ€™s a tiny thingâ€¦
Youâ€™re off to a fantastic start!
