Jamie's Scribepost for November 17, 2009.

Today in class, we started a new unit by making a new foldable with Ms U.

The first question she asked us, was "What do we know about rectangles?"

Our class came up with a couple answers:

• They have 4 sides
• Not all sides have to be the same

After, we had to get into groups of two. Each group of two, had 16 tiles. Our task was to make a rectangle on the grid paper she gave us, with all of the 16 tiles.

We came up with three ways:

1.

A = L x W

A = 4 x 4

A = 16 tiles.

2.

A = L x W

A = 1 x 16

A = 16 tiles.

3.

A = L x W

A = 2 x 8

A = 16 tiles.

Then, Ms U showed us a times table. We checked and circled to see if our answers were true, and if they actually did equal 16.

Next, we were doing something called "Building Squares". We were asked "How many tiles do we need?". But remember, a square has four equal sides. So, these were the answers we came up with:

Then, Ms U showed us a grid with four squares coloured. She asked us, "How many tiles do I need to add in order to make another bigger square?". The answer we came up with was 5 squares.

After that, Ms U gave us this for homework, and these were the answers I came up with:

What is the relationship between the side length of the square and the area?

- You just multiply the side length of square by itself to get the area of the square.

Why are the areas called perfect squares or square numbers?

- I think they are called that, because the sides are all even.

Well, I think that was all for today. I'm sorry if I forgot to mention anything, and if I did, please let me know.
