I wanted to talk briefly about assigning grade levels to the activities I share. More specifically why I don't do it.
I know there are people who would like to be able to search the activities by grade level and at one point I thought about adding labels along those lines.
But then I realized those labels wouldn't do much to narrow down your search, as I'm a firm believer that the bulk of the activities I share can (and should) be done with a very wide range of students.
Let me give you a few examples...
I originally learned the Heart Mambo at a Life Science Institute for middle school science teachers I attended. In its original form, it is clearly meant for 7th grade (give or take...) students to learn the path the blood takes through the circulatory system, with a fair amount of detail (names of the specific arteries and veins through which the blood passes at each point in the cycle).
