Addition and Subtraction Strategies

$0.00

Addition and Subtraction Strategies illustrates how to add or subtract whole numbers using place values and the properties of operations. Students will learn these two strategies and understand how they work and why. They will have a lot of opportunity to practice what they learned through the worksheets.

There are several additional suggestions in the “Options for Lesson” section on the classroom procedure page that you could incorporate into your instruction. One suggestion is to add additional problems to the activity to allow students more practice. You could also have students create their own word problems and exchange them with each other to solve.

Description

What our Addition and Subtraction Strategies lesson plan includes

Lesson Objectives and Overview: Addition and Subtraction Strategies teaches students how to add and subtract in a couple specific ways. Students will learn about place value and the properties of operations. By the end of the lesson, they will see how and why these strategies work.

There are four total content pages in this lesson. Students will first go through a review of what addition and subtraction are and what to call the different numbers in an equation. The lesson then describes what place values are and explains how to figure out what place value a number has.

Further on, students will learn about number lines, cubes, and fact families to help them add or subtract numbers. The lesson describes each of these and provides an example to help students understand the concepts. It also mentions “adding backwards” as another strategy they could use to subtract. This works well especially when the numbers are close to each other.

PROBLEM SOLVE ACTIVITY

For this activity, students must work with a partner to solve a number of word problems. There are five problems total, each with two boxes beneath it. The boxes represent two different strategies the students will use to solve the problem. Students can write out a rough draft explaining each method and then use the boxes for the final explanation. After everyone finishes, you can have the class share with each other the different ways they solved the problems.

WRITE OR DRAW PRACTICE WORKSHEET

There are a couple sections on the practice worksheet. The first section requires students to use the word bank of key terms from the content pages to fill in blank boxes. Next, they will read through a couple word problems. There is space around each problem in which students can draw or explain how they got their answers.

ADDITION AND SUBTRACTION STRATEGIES HOMEWORK ASSIGNMENT

Similar to the practice, the homework contains two sections. The first section requires students to correctly complete 12 fact families. The second section requires them to solve four word problems using the strategy at the end of the sentence. They can show their word in the space beneath the word problem.

Excellent!!

This packet was amazing andhelpful especially in this time where the kids are out of school. The packet provides instructions for the teacher (or parent) so that you know how to teach the subject to your student (or child). Then they provide easy directions for each activity the child does and also great variety. Im so pleased with Clarendon Learning!
