What our Addition Sentences lesson plan includes

Lesson Objectives and Overview: Addition Sentences focuses on translating addition sentences from symbols (3) into words (three). The lesson includes a helpful chart which lists the symbol and word for the numbers 1 through 20. The symbols and words for the plus (+) and the equal (=) signs are also listed. At the end of the lesson, students will be able to translate between written words and symbols for 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 only supplies needed for this lesson are the handouts. To prepare for this lesson ahead of time, you can copy the handouts and prepare index cards with numeric and mathematical symbols on them.

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 have your students use pictures to represent addition sentences along with the words and symbols. You could also have students create their own addition sentences for the class during the activity. Finally, you could give students time to practice learning to spell numbers as words.

Teacher Notes

The teacher notes page includes lines that you can use to add your own notes as you’re preparing for this lesson.


Addition Sentences

The Addition Sentences lesson plan includes one page of content. The lesson begins by stating that we can also write numbers as words! For example, “3” is the symbol and “three” is the word. Both of these are correct and show the same amount. The lesson includes a helpful chart that lists numbers in symbol form and word from from 1 – 20.

Numbers are not the only math words that have symbols. Math symbols often represent more than one word. We can write an equals sign (=) in word form as “equals” or “is.” We can also write the plus sign (+) as “added,” “plus,” and “altogether,” amongst others.

The lesson then explores two different types of addition sentences with examples. We can write 7 + 9 = 16 in words as Seven plus nine is sixteen. However, the equal sign does not always have to go at the end of an addition sentence. You can have 5 = 4 + 1, also written in words as Five equals four plus one.


The Addition Sentences lesson plan includes four worksheets: an activity worksheet, a practice worksheet, a homework assignment, and a quiz. You can refer to the guide on the classroom procedure page to determine when to hand out each worksheet.


Each student will have an index card with a symbol on it (either a number, a plus sign, or an equals sign). The teacher will write an addition sentence on the board and the students with the corresponding cards will come to the front of the room to create addition sentence using the symbols on their cards. They will repeat this with several different sentences. The teacher will shuffle the cards and hand them back out to the students periodically.


The practice worksheet asks students to write the addition sentences using symbols.


For the homework assignment, students will complete two short activities. First, they will draw the symbols to match the words for the numbers one through twenty, plus, equals, and is. Next, they will create their own addition sentence and write it with both words and symbols.


This lesson also includes a quiz that you can use to test students’ knowledge and understanding of the lesson material. The quiz asks them to first write the words for the given addition sentence (written in symbols). Next, they must write the symbols for the given addition sentence (written in words).

Worksheet Answer Keys

This lesson plan includes answer keys for the practice worksheet, the homework assignment, and the quiz. 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.
