When we make our roofs, they will need an overhang to protect people from rain and they also look cool. The overhang hangs off 1 meter long on each side so the stone part is 8 meters long how long will the roof be? (the brick slabs) 10 8

When we make our roofs, they will need an overhang to protect people from rain and they also look cool. The overhang hangs off 1 meter long on each side so the stone part is 5 meters long how long will the roof be? (the brick slabs) 7 5

10 8 7 What pattern do you see? 5

7 10 3 7 Each side of you roof is 2 meters longer than your walls. What is the area of this roof? 7 10 3 7

Each side of you roof is 2 meters longer than your walls. What is the area of this roof? 7 21 70 10 3 7 70+21=91 meters squared

91/2= 45 ½ so will need 46 blocks to make 91 slabs Roof=46 R=46 1 Block makes two slabs, if my roof has an area of 91 how many blocks do I need to make the slabs? 91/2= 45 ½ so will need 46 blocks to make 91 slabs Roof=46 R=46

A facade is the decoration on the outside of a building, here are some cool facades.

A facade can also have a use like a front porch to sit on. Let’s make a porch on a Minecraft house.

32 A facade can also have a use like a front porch to sit on. Simply just put a loop of slabs or upside stairs around the perimeter. Don’t fill in the corners How many slabs are on this porch? 32

1 Block makes two slabs, if my porch needs 32 slabs, how many blocks do I need to make the slabs? 32/2= 16 so will need 16 blocks to make 32 slabs

A facade can also be used to support the weight of the roof A facade can also be used to support the weight of the roof. That is why I added these 5 fences columns with 4 fences in each. How many fences are there? 5x4=20

If you need 46 blocks for your porch and 20 blocks for your columns how many blocks total do you need for your facade? 16+20=36 Facade F=36

Putting It All Together! About how many blocks does it take to build your house?

Area=55 Walls=128 Roof=46 Facade=36

Area=55 Facade=36 Roof=46 Walls=128 Total=265

The Big Idea: Math is needed to create buildings. Measuring the area and perimeter of shapes are its tools.
