HOW DO WE COMPARE?

WHAT DO WE NEED FOR MATH:

Everyday Math Journals p. 57 Pencils Extra paper (1 sheet) Handout Math Masters (yellow) Everyday Math Cards White boards and markers

OUR GOALS

We will create the numbers 1 million, 1 billion and 1 trillion by using index cards with the correct numbers on them as well as using equations in base ten.

We will compose a reflection explaining the similarities and differences between the 3 numbers 1 million, 1 billion and 1 trillion.

We will compare two multi-digit numbers based on the meanings of the digits in each place, using <, = and > in comparison.

IN LARGE GROUPS

Group into groups as follows by using the number on the blue index card on your desk: 1 and 6 2 and 5 3 and 4

In your group, take 2 minutes to read over the poster in front of you. Answer the questions on the poster and be prepared to share all of the information on the poster to your class.

WHAT DO THESE NUMBERS LOOK LIKE?

Page 57 in Everyday Math Journal

1 million = 1,000,000 1 billion = 1,000,000,000 1 trillion = 1,000,000,000,000

1 thousand times 1 thousand = 1 million 1 million times 1 thousand = 1 billion 1 billion times 1 thousand = 1 trillion

What is a similarity here? What does this look like as numbers?

INDEX CARD SHUFFLE

Get into your groups by the number on your blue index card.

Start the index card shuffle.

HIGH NUMBER TOSS

Sort your Everyday Math cards into 2 piles. The pile on the left should include the

numbers 1-5. The pile on the right should include the

numbers 6-12. All other cards can de set aside.
