Lets get started

Chapter 1 1/16 th Scale

This is the 16 th scale

You can seen that between 0 and 1 there is 16 marks

Each mark = 1/16

Two marks = 2/16 or 1/8

Four marks = 4/16 or 1/4

Two marks = 6/16 or 3/8 Do you see the pattern yet?

Every time it is on the small line it will be a 16th

Every time it is on next biggest line it will be a 8th

The next biggest line will be a 4 th or a quarter

The line with the 16 under line is in the middle of zero and 1 this is = 8/16, or 1/2

Okay lets try a few

Chapter 4 Multiplying fractions

Rules for Multiplying fractions Multiply both top numbers Multiply both bottom numbers The bottom numbers do not have to be the same! Example: 1/2 X 1/4 = 1/8 1x1 = 1 2x4 = 8

Lets try some.

Click the best answer: 3/16 1/2 1/4 1/16 1/8 x1/2=?

Congratulations !! You passed chapter 4

Chapter 5 Dividing fractions

Rules for Dividing fractions Flip the second fraction Multiply both top numbers Multiply both bottom numbers The bottom numbers do not have to be the same! Example: 1/2 divided by 1/4 = 2 1/4 becomes 4/1 1x4 = 4 2x1 = 2 So you get 4/2 which equals 2

Chapter 6 Centering a Drawing

In This Chapter you will be creating a Basic drawing that will need to be centering on the design sheet by using the drafting tools. The drawing will be handed for review.

You will be handing in a drawing that looks like this

To get started you will need to get a few supply’s

You will be graded on: Accuracy of measurements Accuracy of centering the drawing Neatness The proper use of drafting tools

Supply’s You will need to get: A scale

Supply’s A Triangle

Supply’s Tape

Supply’s A pencil

Supply’s A drafting board

Supply’s And a sheet of the design paper (8 ½ by 11 paper with the boarder)

Supply’s You will use all these tool to create your drawing A pencil A scale A Triangle A drafting board Tape And a sheet of the design paper (8 ½ by 11 paper with the boarder)

Step 1 Tape your paper down so that it parallel with your boards parallel. It should look like below

Step 2 Find the center Draw a line From corner to corner. Draw lightly So it can be erased

Step 2 (cont.) Find the center Draw the other line From corner to corner. Draw lightly So it can be erased

Step 2 (cont.) Find the center The center is where these Lines cross

Step 3 Find the area needed Add up the top view length + side view width + the spacing in between

Step 3 (cont.) Find the area needed Add up the top view width + top view width + the spacing in between

Step 3 (cont.) The area is 10 ½ by 6 ½

Step 4 Find the center of our rectangle or area Length divided by 2 10 ½ divdded by 2 = 5 ¼ Width divided by 2 6 ½ divided by 2 = 3 ¼

Step 5 Measure rectangle area from center Draw the Rectangle Use measurements from step 4 Draw lightly So it can be erased 3 1/4 5 1/4

Step 6 Erase centering lines

Step 7 Lay out Front view & Side view Draw a horizontal line 1 ½ inches From bottom

Step 8 Lay out Front view & Top view Draw a Vertical line 1 ½ inches From left side

Step 9 Lay out Side view Draw a Vertical line 3 inches From right side

Step 10 Lay out Top view Draw a horizontal line 3 inches From top

Step 11 Erase all the extra lines
