Check out all the tutorials we are creating on ShowMe.  Here is a video that explains how to find primary factors using the tree diagram.  The video shows the corrections from the homework. Page 65 Q 5.  Remember extra help is Monday at lunch.  Anyone having trouble with division should attend extra help Monday for a review.  Feel free to post your own tutorial video in our class group (yezn) and once I watch it I will approve it for the class to see.
