How long should this lesson take?

The videos are working for this activity.

I loved this lesson! I thought it was super engaging and a great way to have the students play with the concepts. I asked them to reflect on the lesson and here are some of their comments: -This has been my favorite lesson so far. I hope they continue to make more like this. I would recommend it to another teacher to use. - This is the best mathalicious out of all the great ones we already did. At first I thought it wouldn't help me learn anything, but then after it was finished I wanted to do another one. - I'm glad we did this. It was fun, made me think harder and out of the box, and taught me new definitions I didn't exactly know. -I really enjoyed this lesson. I couldn't have thought about a better way to show these terms. iPhones are also something kids know in and out. It is easily related to daily lives. It is a great lesson and I couldn't imagine any way to show it better. -The transformers lesson was not only very fun, but I learned a lot from it. I gained a great amount of knowledge on translation, dilation, rotation, and reflection. I thought it was very fascinating to see how these four things are incorporated in an iPhone. thanks guys! keep up the awesome work :-)
