The work sheets are progressive. I encourage students to look for the easiest method that applies to the numbers given: sometimes the attention is vertical (up or down), sometimes horizontal (left or right), and sometimes it is diagonal (multiply diagonally and divide by the other number). One instruction page, followed by four work pages and four answer keys.
