Reflection: Connection to Prior Knowledge 3D Vectors and the Dot Product - Section 1: Launch and Explore

 

A big part of today's lesson was to review the concept of a vector - something we studied many months ago. I made our review of this prior knowledge very informal; students just discussed with their table and then we discussed as a class. Some other options for this review of prior knowledge would be Math Graffiti (as described in this lesson) or using whiteboards. These options might bring out deeper thoughts and each group would have a written record of what they wrote down. Having that written record is always helpful as a teacher when I pull everyone's thoughts together for our group discussion.

3D Vectors and the Dot Product

Unit 12: Math in 3D
Lesson 3 of 9

Objective: SWBAT work with 3D vectors and define the dot product.

Big Idea: 3D vectors are a natural extension of the work we did in two-dimensions.
