For those of you who already purchased the "Subtraction Word Problem Workbook," this an effective and affordable addition. Consider purchasing the "Extra Help Bookmark" that gives struggling students a handy reference to help them recall and apply the subtraction word problem steps.
The Common Core Standards ask us to create effective learners who can see a problem and solve it correctly in a variety of ways. It is no longer about the “answer” or the “destination,” but rather a push for the identifying the “question” or “problem”, seeing multiple ways to apply oneself to solve it, and utilizing these learning tools on the “journey.” I have created these subtraction word problems to help students not only understand the process of subtraction, but to help them fully explore how to be effective problem solvers who implore these skills anytime they are challenged. In solving one subtraction word problem, students solve it in three ways. First, they solve it by creating a visual representation by drawing a picture of the problem. Second, they draw counting dots to represent the numbers in the problem. Third, they count on their fingers. Not only does this allow the students to solve a problem in three effective ways, but it allows them to correct his/her errors along the way as well as make them confident in his/her problem solving endeavors.
Common Core Connections
Operations and Algebraic Thinking K.OA
Understand addition as putting together and adding to, and understand
subtraction as taking apart and taking from.
1. Represent addition and subtraction with objects, fingers, mental
images, drawings2, sounds (e.g., claps), acting out situations, verbal
explanations, expressions, or equations.
2. Solve addition and subtraction word problems, and add and subtract
within 10, e.g., by using objects or drawings to represent the problem.
3. Decompose numbers less than or equal to 10 into pairs in more
than one way, e.g., by using objects or drawings, and record each
decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
4. For any number from 1 to 9, find the number that makes 10 when
added to the given number, e.g., by using objects or drawings, and
record the answer with a drawing or equation.
5. Fluently add and subtract within 5.
