Hi Chase, when I taught this is was before my days of using Formative. At that time, I took my 3rd graders to the next level like this: I took an overhead spinner, drew a clock face on it, and flicked it. I told the students I could tell them about what time it was if that spinner showed only the hour hand. They thought I was crazy, but when I showed them where the hour hand is at :30, at :15, and at :45, they were shocked to find the relative distance of the hour hand between the two marked hours. We played as a class for awhile. I would flick the spinner and call on students who told me about what time it was on the clock and WHY they decided on that number of minutes in the time.
So, to put this in Formative, I would have pictures of clocks with various hour hands. I would then have Short Answer responses to have student tell what time it is and why they chose that time. Then I could have a whole class discussion and grade it ‘on the spot’ with class input.
