Understanding Word Problems: Mixed Operations – Identify operation keywords – Look for words like ‘sum’, ‘difference’, ‘product’, ‘total’, which indicate the required operation. – Read the problem thoroughly – Take your time to read every detail in the problem to avoid missing key information. – Understand the question asked – Make sure you know what the problem is asking. Is it asking for a total, a remaining amount, or a comparison? – Break down into smaller parts – Divide the problem into steps, solving one part at a time to simplify complex problems. | This slide aims to equip students with strategies to tackle word problems involving mixed operations. Emphasize the importance of identifying keywords that hint at the operation needed to solve the problem. Encourage careful reading to ensure all details are considered and the question is fully understood. Teach students to break down problems into smaller parts, making complex questions more manageable. Provide examples of keywords for each operation and demonstrate how to dissect a problem step by step. Practice with the class by reading problems together and discussing the clues and strategies to solve them.

Addition and Subtraction in Word Problems – Calculate total apples – If starting with 15 apples and buying 20 more, how many in total? – Determine remaining candies – If you have 40 candies and give 12 away, how many do you have left? – Practice problem-solving – Understand real-life application – Use these skills to solve everyday problems involving money or sharing. | This slide introduces students to solving addition and subtraction word problems, a key skill in sixth-grade math. Start with the apple example to demonstrate addition in a real-world context.
