Students should be encouraged to look for phrases like ‘in all’, ‘together’, and ‘total’ to indicate addition, while ‘left’, ‘after’, and ‘fewer’ often suggest subtraction. Understanding the context is crucial; it’s not just about the numbers but also about the story and what is logically happening in the problem. Provide students with example problems and guide them through the process of identifying keywords and context to determine the correct operation. This will help them become more confident in tackling word problems independently.

Addition of Whole Numbers – Lining up numbers for addition – Place numbers with the same place value in columns – Understanding carrying over – Carry over when the sum exceeds 9 in a column – Adding multi-digit numbers – Stack numbers vertically and add one column at a time – Practice with word problems – Solve real-world problems using addition | This slide introduces students to the fundamental concepts of adding whole numbers. Start by explaining the importance of aligning numbers by their place value to ensure accurate addition. Discuss carrying over, a crucial step when a column’s sum is greater than 9, and how to transfer that value to the next column. Demonstrate adding multi-digit numbers with examples, ensuring to add from right to left, one column at a time. Conclude with word problems that apply these skills in practical scenarios, reinforcing the concepts. Encourage students to work through problems step-by-step and verify their answers. Provide additional practice problems for homework to solidify their understanding.

Subtraction of Whole Numbers – Lining up numbers for subtraction – Place numbers vertically with place values aligned – Understanding borrowing – When the top digit is smaller, borrow from the next left value – Subtracting multi-digit numbers – Subtract each column starting from the right – Practice with word problems | This slide introduces students to the concept of subtracting whole numbers, focusing on the correct alignment of numbers, the process of borrowing, and the subtraction of multi-digit numbers. Emphasize the importance of stacking numbers with care, ensuring that each digit is in the correct place value column. Explain borrowing as ‘regrouping’ to make subtraction possible when the top digit is smaller than the bottom digit. Work through examples of multi-digit subtraction, starting from the rightmost digit and moving left, borrowing as needed. Include word problems to apply these skills in practical scenarios, reinforcing the concepts with real-world relevance. Encourage students to solve problems step-by-step and to check their work for accuracy.
