I think that principle 3 really resonated with me as it talked a lot about working memory and breaking the instructions up for students to best learn. This really resonated with me because I found that sometimes in math class, things can get lost due to the number of things being thrown at students, and therefore, this answered the wondering I had of why. This can then allow me to take working memory into account when I am teaching and to make sure the students get enough time that they need to work on the topic as well as to fully understand the lesson. I think that if more time is given and if lessons get broken down more for students to understand, it will then allow students to understand the lesson better.
