  1. Following Directions Lesson

  2. Following Directions Lesson • Take out a clean sheet of notebook paper and something to write with. • Place it in front of you on your desk.

  3. Following Directions Lesson • Fold your paper in half long ways “hot dog style”.

  4. Following Directions Lesson • Open your paper up and place it holes away from you on your desk. • Draw a line all the way down the crease on the paper. • “DO NOT WRITE ON THE DESK!!”

  5. Following Directions Lesson • Fold the paper in half the other way “hamburger style”. • You can see my line because I used a Sharpie Marker and it bled through the paper.

  6. Following Directions Lesson • Open the paper up with the holes away from you. • Draw a line from the center of the paper to the ‘margin’ mark closest to you.

  7. Following Directions Lesson • Fold the paper like you had it last “hamburger style”. • Then fold it over again in the same direction as you folded it last.

  8. Following Directions Lesson • Open the paper up. • Draw a line on each of the creases half way to the bottom margin. • Then fold your paper back up like you last had it.

  9. Following Directions Lesson • Fold the paper over one more time in the same direction as your last fold, making it even more slender.

  10. Following Directions Lesson • Open the paper up. • Draw lines on the four creases half as long as the last lines you drew, or ¼ of the way to the bottom margin.

  11. Following Directions Lesson • Draw small lines on our paper in between each of the lines already on your paper and the left and right edges. • Make the lines extend down and be half as long as the last lines drawn.

  12. Following Directions Lesson • Next, draw lines on the left and right edges all the way down below the margin, half way between the margin and the bottom of the paper. • And in case you haven’t already figured it out, we are making a ruler.

  13. Reading a Ruler • Now all you have to do is count the lines as you go from left to right. 3 5 1 7 9 11 13 15 2 6 10 14 4 12 8 16 0

  14. Reading A Ruler • By counting you realize that you have 16 equal parts to an inch. • Next you show each number as a fraction or portion of the total number 16. 0

  15. Reading A Ruler • Next, you must remember from math that a fraction should always be expressed in lowest possible terms. • 1/16 for example is in its simplest form, it cannot be simplified any farther. • 2/16 however, can be simplified. 2 is the numerator (top number in a fraction) 16 is the denominator (bottom number in a fraction)

  16. Reading A Ruler • 2/16 can be reduced by 2. This means that both 2 and 16 are divisible by 2. • 2 divided by 2 = 1 • 16 divided by 2 = 8 • Therefore our simplified fraction will be 1/8.

  17. Reading A Ruler • Now lets take 3/16, will it simplify? • I bet that someone said yes! • Some people look at the three as the numerator and the six in the sixteen (denominator) and automatically think that this fraction will simplify. • However, it will not simplify. • 3/16 is already in its lowest terms.

  18. Reading A Ruler • Next, lets look at 4/16. • Yes it will simplify. • There are two ways to simplify fractions like this one. • If you’re a math wiz, you might say that 4 will go into 16. • If you do, you are right. • You can divide the numerator into the denominator. • This is the quickest of the two ways, but you can divide both the numerator and the denominator by 2, twice. • You have to be careful to get fractions like this one into lowest possible terms.

  19. Reading A Ruler • The easiest way to deal with 4/16: • 4 divided by 4 = 1 • 16 divided by 4 = 4 • Your simplified fraction is ¼.

  20. Reading A Ruler • The other way to deal with 4/16 is: • 4 divided by 2 = 2 • 16 divided by 2 = 8 • Your fraction is 2/8, but is it simplified to lowest possible terms? NO, you have to simplify again. • 2 divided by 2 = 1 • 8 divided by 2 = 4 • Your simplified fraction is 1/4

  21. Reading A Ruler • Now that you know how to simplify these fractions, you finish simplifying the rest of the fractions on your ruler.

  22. Reading A Ruler • Now Check your fractions against these correct answers. 1/16 3/16 5/16 7/16 9/16 11/16 13/16 15/16 1/8 3/8 5/8 7/8 1/4 3/4 1/2 1 0

  23. Now that you know how to use a ruler, here are some short cuts for you. • As you have noticed, the lines are different lengths on the ruler. • As we go across one more time pay attention to the line length and the denominator associated with it. Reading A Ruler 1/16 3/16 5/16 7/16 9/16 11/16 13/16 15/16 1/8 3/8 5/8 7/8 1/4 3/4 1/2 1 0

  24. Reading A Ruler • Did you notice a trend? • The longest lines were of course whole numbers. 1 0

  25. Reading A Ruler • The second longest line is 1/2. • The third longest line has a denominator of 4. 1/4 3/4 1/2

  26. Reading A Ruler • The fourth longest lines always have a denominator of 8. 1/16 3/16 5/16 7/16 9/16 11/16 13/16 15/16 1/8 3/8 5/8 7/8 • The shortest lines always have a denominator of 16.

  27. Reading A Ruler • Now let’s look at the whole ruler. Can you tell me what would be the correct measurement for the letter A. • The answer is 5 7/16. • You start at the whole number and you add the calculated fraction to the whole number to give the correct distance. A 6 5

  28. Reading A Ruler • What is the correct measurement for the letter A. • The answer is 10 3/16. • What is the correct measurement for the letter B. • The answer is 10 3/8. • What is the correct measurement for the letter C. • The answer is 10 3/4. A B C 11 10

  29. Reading A Ruler • Now you know how to read a ruler and deal with the fractions involved. • But these are measurements, and have to be expressed as measurements. Write the following notes on your paper. • The standard ruler is to be expressed in inches or in. or “. Example: 1 ½” • 12 inches is equal to 1 foot or ft. or ‘. Example • 4’ 1 ½” • Three feet is equal to 1 yard or yd. 15/16

  30. Reading A Ruler • See if you can tell the measurements of the objects on the following screens for a quick quiz. • On the back of your paper title it Measurement Quiz and number from 1 to 5.
