#### Slide 1 -Tekstslide

Learning goals
At the end of this lesson I can:
•   Manage my time and tasks effectively (ATL: Self-Management)
• Use skills and knowledge in multiple contexts (ATL: Critical thinking)
• (Re)consider the process of learning (ATL: Reflective skills)

#### Slide 2 -Tekstslide

Share your findings with the whole class

Solution:

#### Slide 4 -Tekstslide

Solution:

Atrapezium = 0.5 x (30 + 42) x 15.5 = 558 ft2

Total Area = 2 x 558 = 1116 ft2

$3 per ft2 Total cost = 3 x 1116 =$3348

#### Slide 5 -Tekstslide

Student question
If Johny has a bucket filled with 4.765kl, and he wants 11L, how much would he need to fill/take away to get his reached goal?

#### Slide 6 -Tekstslide

Student question
If Johny has a bucket filled with 4.765kl, and he wants 11L, how much would he need to fill/take away to get his reached goal?

4.765 kL = 4765 L

4765 - 11 = 4754 L

He needs to empty out 4754 L

#### Slide 7 -Tekstslide

Volume and capacity
1. Find the volume of this prism

2. Find the capacity of this prism

Bonus:
3. What would be the weight of the prism if it was filled with seawater (you can ignore the weight of the sides of the prism)

#### Slide 8 -Tekstslide

Volume and capacity
1. Find the volume of this prism
Atrapezium = 0.5 x (6 + 10 ) x 5 = 40 cm2
VPrism = 40 x 20 = 800 cm3

2. Find the capacity of this prism
800 cm3 = 800 ml = 0.8 L
Bonus:
3. What would be the weight of the prism if it was filled with seawater (you can ignore the weight of the sides of the prism)

#### Slide 9 -Tekstslide

Volume and capacity

Bonus:
3. What would be the weight of the prism if it was filled with seawater (you can ignore the weight of the sides of the prism)

1 L of seawater weighs approximately 1.025 kg.

0.8 L will weigh 0.8 x 1.025 = 0.82 kg

#### Slide 10 -Tekstslide

I have 2 workpackets:

- Length, perimeter, area
- Volume, capacity, mass
You will choose 1 workpacket to work on today.

(You can borrow the answer key from my desk)
