Reflection: Connection to Prior Knowledge Graphing Sine and Cosine Functions (Day 1 of 2) - Section 2: Graphing y=sin x


Today I was excited to hear a student state that the graphing we are doing with sine and cosine is like what we did earlier this year with functions. This student was able to quickly determine how to graph sine and cosine because of the connection with our first unit.  Other students that sometimes struggle with new ideas were quickly remembering how to graph. The questions students ask such as "So you started the period at the low point because the number was negative?" This question seemed to be more validation and students thinking out loud instead really not understanding. I find that some students just want validation for their thinking.
