Welcome to Pre-Algebra ! Tuesday.

1. Please have your homework( 5 drawings: Mug, Zug, Lug, Bug, and Thug) on your desk and get started on your warm up.

2. Discuss and look at 5 drawings

3. Please get out your journal– Problem 2.1

4. Class discussion on Problem 2.15. Homework

– Follow up 2.1

Problem 2.1Problem 2.1Lurking among the members of the Wump

familyare some imposters who, at first glance, look

likethe Wumps but are actually quite different. In

yourjournal:

Describe Mug’s shape.

Compare the other four characters to Mug. Who are the imposters?

What things are the same about Mug and Zug? Mug and Lug? Mug and Bug? Mug and Thug? What things are different? Think about the general shape, the lengths of sides, and the angles of each figure.

Follow up 2.1Follow up 2.11. In Mathematics, we say that figures

like Mug and Zug (but not Mug and Lug) are similar. What do you think it means for two figures to be mathematically similar?

2. The members of the wump family are all similar. How do their corresponding sides compare? How do their corresponding angles compare?

Warm-up Wednesday

Use the rectangle to answer the questions.

1.Please get out your spiral notebooks Intro 2.2

Nosing Around

All the members of the Wump family have the same angle measures. Is having the same angle measure enough to make two figures similar?

All rectangles have four right angles.◦ Are all rectangles similar?◦ What about these two rectangles?

In this problem, you will investigate rectangles more closely to try to figure out what else is necessary for two rectangles to be similar.

You will compare side lengths, angle measures, and perimeters.

How does Zug’s nose compare with Mug’s nose?

How many of Mug’s noses can you put in Zug’s nose?

One way to compare two quantities is to form a ratio. For example, Mug Wump’s nose is 1 unit wide and 2 units long. To compare the width to the length, we can use the ratio 1 to 2, which can also be written as the fraction

Warm-up: Thursday

• Draw any rectangle that is not a square. Then draw a rectangle with side lengths that are twice the side lengths of the original rectangle.

1.How many copies of the smaller rectangle will fit inside the larger rectangle?

2.Will you get the same answer for part a no matter what side lengths you choose for the original rectangle?
