I was browsing Currclick and saw this title. I made the mistake of reading it out loud and had three girls begging me to get it for them. We are in the middle of break so they haven't done the work, but I read through it.
The concepts are presented logically and clearly. Students are presented an opportunity to practice in their own Minecraft world and the real world.
For area, the units are spelled out in read of the standard abreviations [square meters instead of m(2)]. The hands on work is limited, not enough to cement the concept in a child's mind if this is the only resource used on the topic
This is a good, fun supplement, that students interested in Minecraft will enjoy.
