Yes! Besides setting the mixed practice (problem set) part of each lesson to odds or evens, you can completely skip certain parts of a lesson. For example, maybe you go over the lesson practice with your student each lesson and don't want them to have to check those with My Math Assistant. You could check the box next to Skip Lesson Practice. Find these settings on your parent dashboard under the "Settings" for each student:
You can also skip Investigations or Tests if you prefer to handle those differently. Facts Practice can be turned on or off by checking or unchecking the "Skip Facts Practice" checkbox. Turning on the Test Prep videos just means that an extra tab will appear for your student on each lesson, giving them a Test Prep video to watch. They can alternatively watch the Test Prep videos at any time on their Test Prep menu.
