Understanding Addition in Word Problems – Define Addition – Addition combines two or more numbers into a total. – Identify Addition Keywords – Look for words like ‘total’, ‘in all’, ‘together’, ‘combined’. – Solve an Addition Example – With 3 apples and 2 more, we add 3 + 2 to find the sum. | This slide introduces the concept of addition in the context of word problems. Start by defining addition as the process of finding the total or sum when combining two or more numbers. Highlight key vocabulary that often indicates an addition problem, such as ‘total’, ‘in all’, ‘together’, and ‘combined’. Use the apple example to show a practical application of addition: if a student has 3 apples and gets 2 more, they combine the amounts by adding 3 + 2 to find out they now have 5 apples. Encourage students to visualize the problem with actual objects or drawings to reinforce the concept. The goal is for students to recognize addition scenarios in word problems and to feel confident solving them.

Understanding Subtraction in Word Problems – Subtraction: Removing numbers – Clues for subtraction problems – Words like ‘less’, ‘fewer’, ‘give away’ indicate subtraction – Example: 5 oranges – 2 oranges – Start with 5, give away 2, you have 3 oranges left – Solving subtraction in stories – Apply subtraction to real-life scenarios for better understanding | This slide introduces the concept of subtraction as it appears in word problems, which is a key skill for fifth graders. Subtraction is explained as the process of taking away numbers from a group. The slide highlights keywords that can help students identify subtraction problems in text, such as ‘less’, ‘fewer’, and ‘give away’. An example is provided to illustrate how subtraction works in a practical context, using a relatable scenario of having a certain number of items and then giving some away. The notes should guide the teacher to emphasize the importance of understanding the context of a problem to correctly apply subtraction. Encourage students to think of subtraction as not just taking away, but as finding out how many are left or the difference between amounts. This understanding will be crucial as they tackle more complex word problems.
