Description
What our Addition with Regrouping lesson plan includes
Lesson Objectives and Overview: Addition with Regrouping teaches students about using the properties of addition and regrouping. This lesson also covers strategies for solving word problems using addition and working with addition equations. At the end of the lesson, students will be able to add using the properties of addition, and regrouping, including solving word problems using addition and work with addition equations. This lesson is for students in 2nd grade and 3rd grade.
Classroom Procedure
Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the blue box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. The only supplies you will need for this lesson are the handouts. To prepare for this lesson, you can pair students for the activity worksheet, find scissors for the activity, and copy the handouts.
Options for Lesson
Included with this lesson is an “Options for Lesson” section that lists a number of suggestions for activities to add to the lesson or substitutions for the ones already in the lesson. One optional addition to this lesson is to use manipulatives to help explain regrouping during the lesson. For the activity, you can make extra copies of the number cut-outs for students to use to help them solve the problems. You can also increase the number of problems that students will create using the cut-outs. Students can also create their own word problems to swap with a partner. Finally, you can have students practice using interactive sites.
Teacher Notes
The teacher notes page includes a paragraph with additional guidelines and things to think about as you begin to plan your lesson. It notes that you will need to make sure students fully understand basic addition before teaching this lesson. This page also includes lines that you can use to add your own notes as you’re preparing for this lesson.
ADDITION WITH REGROUPING LESSON PLAN CONTENT PAGES
Addition
The Addition with Regrouping lesson plan includes two pages of content. The lesson begins with an example of addition: adding one year to your age every year on your birthday! If you are 7, and add 1, now you’re 8. The addition sentence for that is 7 + 1 = 8. The sum of that problem is 8, because the sum is the same as the answer. For the problem 5 + 2 = 7, 7 is the sum.
People add things all day long. When you count, you are adding. We call most of the addition that we do basic addition. This is addition using small numbers, and the sum is usually below 20. If you need to add larger numbers together, you may need to use addition with regrouping. We use regrouping to make groups of tens to add larger numbers. For example, we can represent the number 13 as either 13 ones or 1 ten and 3 ones.
Addition using Regrouping
If you need to add larger numbers together, there are times when you will need to regroup. First, it’s important to make sure you understand place value. For example, for the number 2,359, 9 is in the ones place, 5 is in the tens place, 3 is in the hundreds place, and 2 is in the thousands place.
We also call regrouping for addition “carrying”. The lesson first reviews some addition problems that don’t include regrouping. For these problems, you first line the numbers up according to place value. You then add each place value together using basic addition, and all sums in each column equal less than 10.
If the sum for a place value is greater than 9, you must regroup to solve the problem. The lesson includes the example problem of 68 + 27. In this problem, when you add 8 and 7 in the ones column, you get 15. You put the 5 ones below the ones place and the 1 ten gets regrouped to the tens column. You then add the tens column: 6 from 68, 2 from 27, and the regrouped 1. The final answer is 95. The lesson shows this in detail.
The lesson then includes more examples. Some of these examples only need regrouping in the tens place, but additional examples also show how to regroup in the hundreds and thousands places as well.
ADDITION WITH REGROUPING LESSON PLAN WORKSHEETS
The Addition with Regrouping lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. You can refer to the guide on the classroom procedure page to determine when to hand out each worksheet.
CREATE PROBLEMS ACTIVITY WORKSHEET
The activity worksheet asks students to cut out the numbers on the worksheet and create addition problems that require regrouping. They will create problems with tens, hundreds, and thousands, writing the problems on the provided pages. Finally, they will solve the problems, making sure to show the regrouping.
Students can work either alone or in pairs for this activity.
ADD PRACTICE WORKSHEET
For the practice worksheet, students will solve 25 practice problems.
ADDITION WITH REGROUPING HOMEWORK ASSIGNMENT
The homework assignment asks students to solve word problems. They will underline the addition key word in each problem. They will also answer three questions using a given chart.
Worksheet Answer Keys
This lesson plan includes answer keys for the practice worksheet and the homework assignment. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
