Doubling Rows was created to be broken up into daily practice, however it may be useful as a review too. It is a 20 question, two page (double sided) handout for practice with adding doubles and doubling doubles which can be completed as part of classwork, during math groups, and/or assigned as homework.
The 20 questions include:
drawing doubles of squares (problems one to five),
drawing doubled squares and the double of the doubled squares (problems six to ten),
answering questions about his or her drawings to further understand the concept of doubling the squares (problems one to ten), and
mental addition of doubling numbers and doubling doubles (problems eleven to twenty).
