I had challenging thing but also not challenging thing during this unit. The challenging thing was to draw a number line. Because I am a person who is not using a number line very much. So it was hard for me to draw a number line especially in multiplication question. The not challenging part of the unit is finding the value of x. We didn’t did any thing in this but it was not challenging for me to do. Because I knew how it worked so it was easy to do.
