Product Description
Students who cannot understand story problems or cling on to counting using fingers?

Too many students start working on addition and subtraction facts and strategies (e.g. make 10, doubles) before their concept of addition and subtraction is strong. They master the strategies but flounder with story problems where they need to analyse questions, understand and visualise what is being asked of them. This is especially obvious for those problems involving unknown change or start. How many times have we also observed students stubbornly clinging on to adding and subtracting using their fingers? Many textbooks and even the state standards feature “counting on” or “counting back” as strategies to master math facts when they are not effective in building automaticity and fluency.

What this set of worksheets does

This set of worksheets is specially designed to give students a strong, intuitive, visual understanding of addition and subtraction before they start learning math fact strategies.

It is designed to strengthen their sense-making and abstract reasoning skills as outlined in CCSS.Math.Practice.MP1 and 2 and help them master the requirements of CCSS.Math.Content.1.OA.C.5. This will give them a strong foundation towards mastering CCSS.Math.Content.1.OA.C.6 of the Common Core Mathematics Standards.

Features of the worksheets

These 20 worksheets are designed to:

• Focus on the concept underlying addition and subtraction. At no point are the words “add”, “join”, “subtract” or “take away” used. These words prevent students from gaining a visual, intuitive understanding of the two operations.

• Relieve teachers of marking. Students may peer-check each other’s answers with the answer keys and sign off at the bottom of the worksheet.

• Provide differentiation. Within each worksheet, an * indicates a slightly more challenging problem. By not having extra differentiated worksheets, the teacher’s workload is reduced.

• Focus on the use of “counting on” and “counting back” as foundational, sense-making strategies. Students gain foundational understanding of addition and subtraction instead of learning them as strategies for mastering math facts.

• Avoid drilling. While extensive practice may be helpful to achieve fluency in mastering math facts, it is unnecessary and counter-productive for the conceptual understanding of addition and subtraction. All worksheets contain 4 to 5 questions and can easily be used for homework, morning work, quick review or in math centers.
