What our Addition – Lesson 1 lesson plan includes

Lesson Objectives and Overview: Addition – Lesson 1 introduces students to the basics of addition and teaches addition vocabulary such as the terms “addends” and “sum”. This lesson incorporates physical classroom activities and examples and helps students understand addition concepts through experiential learning. Students will also complete several different worksheets to ensure a full understanding of addition. At the end of the lesson, students will be able to add within 20 (or more), solve word problems using addition, and work with addition equations. This lesson is for students in 1st grade and 2nd 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 supplies needed for this lesson are counters like chips or beads, addition and equal sign symbols, and the worksheets. To prepare for this lesson ahead of time, you can gather the supplies and copy the worksheets. A more detailed breakdown of the preparations for this lesson can be found in the blue box on this page.

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 of the optional additions to this lesson is to use additional resources for the higher numbers for additional practice. If you have students who already understand basic addition, you can start at a later point in the lesson plan, and skip the basics. Finally, you can use dice with more than six sides or larger spinners.

Teacher Notes

The teacher notes page includes a paragraph with additional guidelines and things to think about as you begin to plan your lesson. This page also includes lines that you can use to add your own notes as you’re preparing for this lesson.


What is Addition?

The Addition – Lesson 1 lesson plan includes one content page. The lesson begins by defining addition as adding numbers or different items together. When you count, you are adding. For example, when you count from one to five, you are adding one to each of the numbers. The lesson includes a drawing of a hen and three chickens. Instead of adding them one by one to find the total, you can 1 + 3 to get the total (4) faster. In addition problems, the numbers each have names. We call the numbers that you add together addends, and we call the total the sum. The lesson includes a small diagram that labels both parts of an addition problem. In the problem 1 + 3 = 4, 1 and 3 are the addends and 4 is the sum.

One way to get faster at adding is to memorize adding the numbers from zero to ten together. The lesson includes a helpful chart that you can use to do this!


The Addition – Lesson 1 lesson plan includes two worksheets: a three-part activity worksheet and a homework assignment. You can refer to the guide on the classroom procedure page to determine when to hand out each worksheet.


The lesson activity includes three separate worksheets. For the first worksheet, students will use counters (like chips or beads). They will split their pile of counters into two groups, count how many counters are in each group, and write those numbers down on the worksheet with an addition symbol in between them. They will then add them together and repeat with different numbers!

The second activity page asks students to find the missing addends in various addition problems. For example, they will find the missing addend in the problem 4 + _ = 10.

For the third, and final, activity page, students will create their own addends with a partner. Each partner will receive a dice or spinner. Each student will roll the dice or spin the spinner to find their addend. Their partner will do the same, and then they will add the two numbers together.


For the homework assignment, students will complete four exercises. The first exercise asks them to circle the correct answers for questions about addition. The second exercise asks them write the sum for each addition problem. The third exercise asks them to find the missing addend for each addition problem. The fourth, and final, exercise asks them to solve seven word problems that require them to use addition. All of these exercises will test their knowledge and understanding of the lesson material.

Worksheet Answer Keys

This lesson plan includes answer keys for the activity 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.
