Mental math

Every week I usually have mental math  in class. This is  an activity to improve my computation skills in numbers . I need to do the questions in addition, subtraction, multiplication and division  quickly in 5 minutes.  After 5 min I have to  stop and check my answers. Sometimes I exchange my work with my friend's work. 

My tessellation

In mathematics I  studied the shape and space. In this geometry lesson  I  learnt  to make a  tessellation.  This  picture on the left is the tessellation that I made.  It is very fun to do tessellation because we can learn how to be patient  and careful when color our tessellation.
