Goal:  Create a tape measure that will automatically (no calculation needed) calculate the diameter of a pipe by wrapping it around the outside (circumference) of the pipe.  The tape measure should be able to measure diameters up to 8 inches.  The tape measure should be accurate...

Old time carpenters were able to use framing squares to do amazing design work.  They were able to draw perfect circles with a framing square without using the center point of a circle. Challenge:  Draw a 6 inch diameter circle on a piece of OSB using...

The process for marking an angle using a speed square is shown below. Swing the square until you read the desired angle (33-1/2 degree) on the board's edge (photo top left), and make your mark. The line shown being marked (with pencil) is a 33-1/2 degree angle. Math...

Goal:  You are to make a recommendation on the type of fiber cement lap siding to be used. Should it be prefinished (already painted) or should you recommend unfinished fiber cement lap siding? It will need to be painted if you use unfinished cement lap...

Goal From your experience in wood fabrication and quadratics, develop an original product that has the ability to launch ping pong balls to hit targets at various ranges and heights using a parabolic curve Math Standards A.CED Create equations that describe numbers or relationships. F.IF Interpret functions that...

Not what you think. We are talking about a measure of the size of nails that uses the symbol, d. Why is it called “penny”? In England before the year 1488, the nail size was the price in pennies of 100 nails of that size. For...

Goal: Position 3 sprinkler heads in a 12 feet by 18 feet rectangular lawn to optimize water coverage but to minimize water waste. Watering an area twice is considered waste but watering the street or non-lawn areas is worse. The sprinkler heads are manufactured for...

CTE Goal: Have students understand nailing patterns and the requirements. Students will learn the quantities of fasteners needed for different portions of the home building process. Math Goal: Students will calculate rates (slopes), equations of lines, and graph the equations. Discussion points include finite and continuous, real life...

Math Standards: A.CED.2; A.CED.3; A.REI.11 CTE Standards:  FPP.03.01; FPP.04.01; FPP.04.03 Teacher Note:  The interest in this problem is the use of the Pearson Square method to solve.  It is the commonly taught solution method in Agriculture classes at the college level.  It is interesting that most math...

Mathematical Practice Standards:  Reason abstractly and quantitatively.  Construct viable arguments and critique the reasoning of others. Aaron needs to rip (cut length wise) a 2 x 10 into 3 equal strips.  He does not like working with the ugly number that is the width of the 2 x 10,...
