Here is an example of a lesson on addition.  Laughing

Grade/Subject: 1st grade, Addition of Single Numbers 1/5_____Time Frame: 45 minutes

Lesson Title: Adding Ladybugs and Leaves



COMPETENCY GOAL 1: The learner will read, write, and model whole numbers through 99 and compute with whole numbers.

1.03     Develop fluency with single-digit addition and corresponding differences using strategies such as modeling, composing and decomposing quantities, using doubles, and making tens. 


            Student will learn how to add single digit numbers using various objects.


1.      Pencil

2.      Paper

3.      Ladybug printout (colored and black/white)

4.      Leaves printout (colored and black/white)

5.      Different colored tokens

6.      Sum Colors worksheet

7.      Homework Sheets


Launch:  Divide the class into groups. Within each group hand out an uncounted amount of ladybugs and leaves, each group does not need more than 6 of each. Make sure you as the teacher have at least 10 of the ladybugs and leaves. Ask the class “what is addition” Addition is the sum of two or more numbers.

Content: Addition is the process of adding two or more numbers together that equal a sum. Now addition has a symbol that everyone needs to know and recognize.


Tell the class we are going to do addition together until we understand how to add.

1.      Now a number can be referred as a object, a picture, person etc.

2.      On the board have your ladybugs and leaves on the board. Instruct them to count how many ladybugs are on the board. “5” how many leaves are on the board “2”.

3.      Now that we know how many ladybugs and leaves on the board do you think we can figure out how many ladybugs and leaves are on the board?

+ = 7

4.      As a class count the ladybugs out loud, 1, 2, 3, 4, 5, keep counting while adding the leaves, 6, 7. Now how do you think we can figure out how many objects are on the board? Remember an object is a number. Have your students explain their way they could figure out the answer. There are many other addition algorithms, students will most likely be able to figure the problem out in different way and many students might fail at finding the answer. However, a teacher should be able to encourage students finding out the answer.

5.      The answer is seven. The class should already have an understanding of basic number sense of how many one object is. One brown bear is one brown bear. Now the tell the class your method of adding.

6.      Do another problem….

+  = 4

7.      Do as many problems with the class on the board. Make sure you answer questions and ask questions. Here are some examples to use on the board.

a.      Colored Ladybugs + B/W Ladybugs =

b.      Colored Leaves + B/W Leaves =

c.       Boys + Girls =

d.      Blondes + Brunettes =

e.      Etc.

8.      After you have completed some addition problems as a class have them complete problems within their group with the ladybugs and leaves.

a.      Problems

                                                              i.      1st problem

1.      Ladybugs + Leaves =

                                                            ii.      2nd problem

1.      Color Ladybugs + Colored Leaves =

                                                          iii.      3rd problem

1.      B/W Ladybugs + B/W Leaves =

                                                           iv.      4th problem

1.      B/W Ladybugs + B/W Leaves =

                                                             v.      5th problem

1.      Colored Ladybugs + Colored Leaves =

b.      After each problem, write their answers on the board. Ask them what group has the most or the least objects. Also, make sure you travel to each group to see how the group is working together and to assist. Lastly, make sure the students tell you each amount, and their answer.

c.       Have the class concur each groups answer. 

9.      Have the class go back to their seat, and hand out tokens and “Sum Color” worksheet.

a.      Instruct the class to work on the sheet doing the same procedure as we did with ladybugs.

b.      If they need help, tell them to ask a classmate then ask the teacher.


Gearing Up: Adding double digit numbers worksheet. Finish 10 problems


Gearing Down: “Adding numbers with 0 or 1” worksheet (10 problems completed) or “Number Line” worksheet.


Assessment: Play “Around The World” with addition flashcards.

            Instructions: The object of the game is to answer the most cards correctly before their teammate

1.      Have a deck of math flash cards, shuffle the cards

2.      To start the game you need a starting place, tell the class the first person to answer this card correctly starts the game. 1+1=___, when the student knows the answer they stand up and answer “2”.

3.      The student that gets it right competes with the person to their right. They stand up together.

4.      The teacher shows the next card, 1+5=__, the first student out of the two standing that answers the correct answer, moves on to the next student to the right.

5.      When a student gets the answer wrong they sit back down in their seat

6.      The game ends when either you run out of cards, or everyone has answered a question.

7.      The deck of cards should carry a easy and moderate level of addition. If both completers cannot answer the question, put the card aside and find the answer as a class later.

This game can be completed later in the day. Do not put an excessive amount of pressure on addition. Make sure that this is a fun game and there is plenty of encouragement.

b.      Apple Addition Worksheet


            After this lesson of basic addition, students should be able to understand single digit addition. It is encouraged that throughout the day you do addition problems and review single digit addition the next following days until the students have a concrete understanding on addition.
