Materials Required


Developing the Concept

Use masking tape to make a horizontal line on a table or the floor, and then help the student gather nine favourite toys or other objects.



Place five of the objects above the horizontal line and four below.

Have the student tell how many objects there are in total and then print a number sentence to match the placement of the objects.



Ask the student to show another way to make the number nine and then print a number sentence to match that placement of objects.


Take turns making various number combinations for nine and printing the number sentences until all possibilities have been recorded.



Applying the Concept

Collecting Information

Have the student ask nine people the following questions.


Would you rather have a dinosaur or an elephant for a pet?

Use tally marks to show the results of the survey, as in the example below.




Explain to the student that the number one is shown as and the number five is shown as .

Help the student use a large sheet of paper to set up a picture graph similar to the one shown below.

Why do you think most people preferred this pet?

What is the difference in number between the dinosaur and the elephant?

Encourage the student to ask these questions of other people.

Next, follow the directions to do Day 18: Assignment 2.

Then complete Day 18: Learning Log. Under Student's Thoughts, print a sentence or two telling what the student thinks about this day's mathematics learning. For example, is it easy to add sums to nine?



At the end of Mathematics Assignment Booklet 4B, follow the directions to complete Day 18, Student Folder Items. Gather the required materials from your Student Folder. Submit these items to your student's teacher for marking at the time the teacher has requested them.
