OK, to remind everyone, I'm now teaching 6th grade math. I will have only 6th grade math, so, there will only be 1 prep. Before I got the news, I was making Powerpoints for each section of the 1st few chapters of 8th grade math for I didn't know I was being swapped. I took a look at the content, the standards, and the textbook for 6th grade and see very simple stuff to teach. Multiplying / dividing fractions.... Multiplying / dividing decimals...... perimeters, areas of circles... Honestly, nothing I really need to brush up on until way later in the year (box-and-whisker plots, interquartile range, etc...) Am I making a mistake by not preparing and just feeling like I can wing it?
