Subtracting and Taking AwayUnknown - 2006
Young readers will use objects found in everyday life to support their learning of number sense and calculation. This book explains how a subtraction problem can be solved by counting back from the first number in a subtraction problem. Each subtraction problem in the book is followed by a step-by-step guide that explains how to solve the problem, and is reinforced by a photograph that illustrates the way the subtraction problem was solved.
