How can a teacher best support first graders struggling with subtraction word problems?

• A. Encouraging the use of count-back or count-up strategies.
• B. Explaining the context of the problems.
• C. Reminding them of prior learning regarding operations.
• D. Explaining the relationship between addition and subtraction.

Answer: (A)

Encouraging the use of count-back or count-up strategies is an effective way to support first graders struggling with subtraction word problems because these strategies help students develop a concrete understanding of the subtraction process. By using counting techniques, students visualize the problem and can physically manipulate objects or use their fingers to count backward from a given number, which reinforces the concept of taking away.

This approach is particularly helpful for young learners as it breaks down the abstract nature of subtraction into more tangible actions. When first graders count back from a number, they are essentially demonstrating subtraction in a way that aligns with their developmental stage. It builds their confidence and fluency in performing subtraction, making it easier for them to tackle word problems in the future.

Additionally, using counting strategies can lead to a better understanding of related concepts, such as the relationship between addition and subtraction later on, which is foundational for their growth in mathematics. This strategy also encourages a growth mindset, as students learn to find and use different strategies to arrive at solutions.
