Mental Math Units: the Complete Subtraction Collection


This unit is priced higher than the others because it is a special Double Mental Math Strategy Unit that includes a wealth of activities for the closely related subtraction strategies of counting back and counting up. These are generally the first strategies that a student will learn when working with mental math subtraction strategies.

Counting back involves beginning with the minuend of the subtraction equation and counting back. For example, in the equation 8-3, a student will begin with "8" in his head and count back "7, 6, 5." In this case the difference is 5.

Counting up involves beginning with the subtrahend of the equation and counting up. For example, in the equation 9-6, a student will begin with the "6" and count up "7, 8, 9." Learning this strategy will help students see that there is a correlation between subtraction and addition, which will prepare them for learning other subtraction strategies, such as "Thinking Addition."

This extensive unit will focus on some of the most visual ways of counting back and counting up, including domino and dot patterns, empty number lines, and number charts.

Similar to the "Counting On" addition strategy unit, this resource is separated into three sections: 0-10, 11-20 and 21-100. This will allow you to choose the activities that best suit your grade level. Additionally, the different sections can be used to differentiate instruction and target specific learning needs within your classroom.

Included is independent seat work, flashcards, center activities, large group kinesthetic learning activities and more!

Enjoy!
