I changed my mind this week and decided to continue with my regular program rather than supplement for a week and extend the other unit. With St. Patrick's Day this week, 2 days out of class and such, it was much easier to just keep going with the flow.
I don't know if my kids like these packets, but some are always so excited to do them. I will keep doing them til the end of the year and then over the summer I plan to start doing them for all the other unit at the beginning of the year.
Please let me know if you use it, what you think, etc. I want feedback please! :)
