Grade 3

Read the Headline Story to the students. Encourage them to create problems that can be solved using information from the story.

Yuji wrote some numbers:

1, 4, 9, 16, 25, 36

What can you say about the number sequence?

- The numbers are in order from least to greatest.
- The first number is odd, the second number is even, the third number is odd, the fourth number is even, and so on.
- The differences between the numbers are odd: 3, 5, 7, 9, and 11.
- The difference between the numbers increases by 2 each time.
- The next two numbers would be 49 and 64.
- The numbers are square numbers, and they can be found by multiplying each counting number by itself:
- 1 X 1 = 2
- 2 X 2 = 4
- 3 X 3 = 9, and so on.
