Tentative Schedule:. Nov : College and Career Fair.Working in the trades requires strong numeracy skills to help you succeed on the job. This workbook includes questions and learning material to help you:. The workbook is divided into four sections, each of which highlights different numeracy skills that journeypersons use on the job.

An answer key is provided at the end of the workbook to help you review your answers and find out which areas of numeracy you may need to improve. Measurement is the way that numbers are used most often in the trades. Measurement and calculation are used to measure and describe the physical world, for example by taking measurements and calculating area and volume.

The following are three typical workplace examples of measurement and calculation:. Journeypersons who build things in their work use measuring tapes, laser survey equipment, micrometers, scales and other tools to measure on a daily basis. They work with both imperial and metric measurements on the job.

Enter the correct length beside each arrow on the measuring tape. Remember to include the correct unit inches or centimetres. Two examples are provided for you. Label the following measurements a—f on the measuring tape with an arrow and the letter of the question. Two examples have been done for you. Carpenters take readings of elevations, directions and lengths of property lines using a levelling rod. The red numbers on the rod represent the number of feet, and the black numbers represent tenths of a foot.

Note: The red numbers are larger than the black numbers when they mark an even number of feet e. Whether you are in a classroom or on the job, it is helpful to develop your own method for solving math problems involving measurements.

The steps below can help you do this. Note: Use your calculator to complete the questions in this workbook. Note: Only whole tiles can be ordered, so you will need to round your answer up when you calculate how many tiles are needed. Think of the cylinder as being laid out flat so that the circumference becomes the width measurement.Request a copy.

Bud Caldwell, one of the best Superintendents I ever worked with, taught me the value of changing inches into decimal feet. We were reviewing a shop drawing for a piece of equipment with lots of anchor bolts, and everything was in feet, inches and fractions of an inch. In his head, he quickly converted the inches and fractions of an inch into decimal feet, so we could easily add and check dimensions.

## Construction Math

He showed me a wonderful little trick of the trade that I've used for over 25 years. The inches to decimal feet conversion table shows illustrates the information. As you know, adding fractions challenges most of us.

We probably learned the concept of lowest common denominator at some point, but struggle to remember how to actually use it. So to add feet and inches, we have to deal with fractions and with that 12" in a foot concept, which means we have to add by hand, using pencil and paper. Special calculators for adding feet, inches and fractions of inches are available, but they always seemed difficult to use for me. So adding a string of dimensions in feet, inches and fractions of an inch gets much easier if we can simply convert to decimal feet.

Let's use accessible route as an example. The sidewalk between the parking space and the front door has a distance of 30'. Then subtract To find the slope, divide the grade change of 1. So it works. To figure how much concrete to order for a slab on grade, you need to know some basic area and volume formulas. Most of us understand that length times the width times the thickness gives us the volume.

We may need a bit more help, though, when the things aren't rectangular or other complexities arise. Let's start with an example and work through how to utilize the geometry of common shapes.

Hopefully, the example above makes sense to you and simply illustrates a few useful concepts. If you need some help understanding the example, you may want to review the US Navy Basic Math and Algebra training class.

NCCER introduces a new applied math book that teaches the fundamentals of math in a way that is engaging, interesting and relevant. Chapter 1 Show Me the Money Mr. Whyte is the teacher and he seizes an opportunity for a math lesson.

In Chapter 1, he uses money to teach the students about decimals and factions as well as division. Chapter 2 It's All About Space The students meet with two potential homebuyers and teach them how to calculate the area of squares, rectangles, triangles and trapezoids.

Chapter 3 Where Do You Live? Whyte teaches the class how to calculate the average cost of a home per square foot using powers of ten. He also explains averages. Chapter 4 Cattle Country Mr. Whyte finds a homebuyer! His team works with a surveyor to learn about angles, direction and bearing, the rule for right triangles and Pythagorean Theorem, as well as more about surface area.

This time he uses payroll taxes to teach the relationship between decimals and percentages and how to perform calculations with percentages.

## Construction Math

Chapter 7 Divide and Conquer The class learns how to divide the irregular shape of the foundation into common shapes so they can calculate its total volume. Chapter 8 Choosing Teams In this chapter, the rough carpentry team learns about linear measurements and how to read factional measurements.

They also learn how to calculate beard feet and perimeters and how to estimate materials for construction. Chapter 9 Gravity Can Work for You or Against You Plumbers use a lot of math, so the students learn about angles, volume, pressure, grades and slopes. They also get an introduction to trigonometry.

**Ohm's Law explained**

Chapter 10 Shocking, Simply Shocking Things are really rolling now. The electrical team learns how to calculate the circumference of a circle, more uses for the Pythagorean Theorem and more about trigonometry. Chapter 12 Inside and Out The kids learn how to apply math skills to finish the interior and exterior of the house. The math in this chapter includes linear measure and surface area of flat and three-dimensional objects, converting between square feet and yards, pitch and span of roofs and calculating the materials needed for a job.

Chapter 13 The Bottom Line The job is almost done and the class learns a bit about running a financially sound business by calculating costs and determining profit. Chapter 14 Everyone Has an Angle This chapter wraps up trigonometry functions, including sine, casine, tangent, cotangent, secant and cosecant.

Date: Dec 30, by Pearson.The carpentry math, used for most projects, can be narrowed down to some basic formulas and computations provided right here on this page. The formulas below can be used to square a wall or deck frame the Pythagorean Theoremcalculate the area of a circlecalculate the volume of a cylindercalculate the circumference of a circleand more. The Pythagorean theorem is used extensively in carpentry and construction.

Almost every carpentry project involves some combination of squares and triangles. The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. The square of side A plus the square of side B equals the square of side C. The square of one side of a right triangle equals the square of the hypotenuse minus the square of the other side.

The length of the square of side A equals the square of side C minus the square of side B. If this sounds complicated, consider the rule of a right-triangle.

It is the best way to square two walls. Here's how it works - if one side of a right-triangle is three feet and the other side is four feet and the hypotenuse or long side of the triangle is five feet, then angle 'A' is 90 degrees see diagram at right. If you want to square something larger, you can use proportions of this same formula, such as The area of a triangle is equal to one-half the product of the base and height.

To calculate the area of a rectangle, simply multiply the length of side 1 by the length of side 2. To calculate area of a trapezoid, multiply its height by one-half the sum of the parallel sides. To calculate the area of a circle, multiply the circumference by one-half the radius. To calculate the circumference of a circle, multiply the diameter by 3. To calculate the volume of a cylinder, multiply the radius squared x 3.
