Mix & match game

You'll get a piece of paper with an answer or a question

Find the person who has your answer or question

Found them? Write question, steps and answer on a whiteboard

Done? Check and/or correct other people's work!

Intended Learning Outcomes

At the end of chapter 6 you could...

• Do calculations with squares and square roots
• Fill in quadratic formulas and draw their graphs (parabolas)
• Simplify letters with adding/subtracting/multiplying

What do YOU want to practice with?

1. Calculate squares and square roots

2. Use quadratic formulas and draw graphs

3. Simplify letters

Some practice

p.42- (M/C):

1, 2

p.46- (B/M):

1, 2, 3, 4

p.42- (M/C):

5, 13, 14

p.46- (B/M):

3, 4, 5, 6

p.42- (M/C):

6 - 11

p.46- (B/M):

7 - 14

What's your opinion?

I think I've got this chapter under control

This chapter is pretty hard, but I think I can make it with enough practice

I really need some extra help / explanations / examples

U-shapes

Let's build a different classroom

Inner U:      extra help

Outer U:     do some exercises, ask some questions

Back row:  go through the exercises alone

Some practice

p.42- (M/C):

1, 2

p.46- (B/M):

1, 2, 3, 4

p.42- (M/C):

5, 13, 14

p.46- (B/M):

3, 4, 5, 6

p.42- (M/C):

6 - 10

p.46- (B/M):

7 - 14

1. -72
2. 24
3. 48
4. 72

1. -17
2. -11
3. 11
4. 17

Calculate:

√​81​​​⋅3​2​​−√​49​​​⋅2​2​​

1. 27
2. 53
3. 63
4. 98

Calculate (write it out!):

(​2​​1​​)​2​​⋅√​1​49​​32​​​​​

1. 1​7​​2​​
2. 5​7​​1​​
3. ​14​​9​​
4. ​28​​9​​

What happens when I fill in
x = 4 or x = -4
into a quadratic formula like

y=​2​​1​​x​2​​−4

1. The answers are different
2. The answers are the same
3. It depends on the formula
4. It's impossible to tell

Step 1

Step 2

Step 3

Step 4

How to draw a graph

Plot the points

Draw a curve

Make a table

Draw a coordinate system

1. The blue graph fits the table
2. The red graph fits the table
3. The orange graph fits the table
4. The green graph fits the table

What to do?

Come to the front for questions

OR

Choose a route in 67 - 77 (skip O/L)

OR

Done with the route? Pick up a special paper

Silently after ~10 minutes
