I have used CK12.org tools more this year.
CK12’s Flexbook system allows you to create a personalized textbook and there are a number of resources that I can use to differentiate instruction. I really like that content provided by CK12.org can be modified and personalized for your class. Change names of students in the example problems and make the content more appropriate to my location here in Vietnam.
In the next semester in my coordinate geometry unit I plan on using these resources to flip instruction and do a little more Scratch programming during my Math 8 class.
As I am relearning how to use the new version of iMovie I thought I would create a short video about creating a pdf based book using ck12.org and have embedded it below.
