Materials Required


Developing the Concept

Addition and Subtraction Song

Sing the following verse to the tune of "London Bridge Is Falling Down," or just chant the verse as a poem.


EyeWire, Inc.


Have the student model each verse with the appropriate number of fingers.


Two plus four equals six,

Equals six, equals six.

Two plus four equals six.

Six, six, six, six.


Six minus two equals four,

Equals four, equals four.

Six minus two equals four.

Four, four, four, four.


Now make up new verses, similar to the previous ones, that will help the student practise adding sums and subtracting differences to six. Substitute words according to what you make up, and have the student continue to model each verse with the appropriate number of fingers.

Use other favourite tunes to create more addition and subtraction songs.

Applying the Concept

Addition and Subtraction Peek-a-Boo Booklets

Encourage your student to show care in the construction of the booklets, add interesting details, and colour the illustrations.


Step 2: Approximately eight centimetres from the bottom edge, cut the top sheet of paper toward the fold, stopping about two centimetres from the fold.



Step 3: This page will be the booklet cover. Ask the student to print the title on the top section.


Step 4: Have the word by and the student's full name printed below the title. Encourage the student to add a

theme-related illustration on the bottom flap of the paper.



Step 5: Ask the student think of an addition number story using a sum to six, such as the one that follows.

Two friends were playing in the snow. Four friends came to join them. How many friends in total are playing in the snow?

Step 6: Have the student illustrate the first number in the story on the top-left inside page and then print the number below the picture.



Step 7: Ask the student to illustrate the second number on the

top-right inside page and print the number below that picture. Then place an addition sign between the two numbers.



Step 8: Draw a straight line from the fold to the outside edge of the page below the illustration of the second number. Under this line, print the sum of the two numbers.


Step 9: Have the student make a second peek-a-boo booklet that shows a subtraction number story.


Step 10: Have the student print the abbreviated form of the module and day numbers, M4D4, on the back of each booklet.

Step 11: Encourage the student to read the addition and subtraction peek-a-boo booklets to family and friends in the following way:

Read the title, and tell who wrote the booklet.

Keep the bottom flap covering the sum or difference, and turn to the top inside page.

Read the first half of the number story from left to right, for example, "Two friends plus four friends equals . . ."

Ask if the listener knows the answer.

Open the flap and reveal the sum or difference.




Step 12: Place both booklets in the Student Folder.



Enrichment (optional)

Visit to the Library

If you have not already done so, you could visit your local library to look for books about addition and subtraction. Refer to the list of books under Additional Resources at the beginning of this module.


Turn to Mathematics Assignment Booklet 4A, and follow the directions to do the assignment for Day 4.

Then complete Day 4: Learning Log. Under Student's Thoughts, print a sentence or two telling what the student thinks about this day's mathematics learning, for example, about the ability to represent information on a picture graph.
