Reflection: Connection to Prior Knowledge Period and Amplitude - Section 1: Warm-up and Homework Review

 

It is always powerful to connect new knowledge to old knowledge.  Students have a much higher chance of remembering something if they relate it to something they already know.  That was the whole purpose of today’s warm up.  My students have been studying functions all year and so all of them have a certain amount of comfort and knowledge.  As you can see in my samples Warm Up 1, Warm Up 2, and Warm Up 3, they each took something they know and went from there.  One student associated that they both have x and y value.  Another related that they both used the same translations.  Most of my students shared that the shape of the graphs are different.  By sharing out, students then saw more connections and hopefully this will cement some of the properties of sine and cosine graphs into their brains.
