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, which is 9 ¼”. Fractions are not his friends and he doesn’t want to divide a fraction by 3

Goal: You will be able to calculate the linear feet of window trim needed for any dimension window. Interior window trim (casing) is a molding that is nailed to the finished window frame to give the window a “finished” look. The trim is located on the inside of the home around the perimeter of the window frame and is often cut at a 45º angle. See picture.

Many homes and commercial buildings have rain gutters. The gutters were originally designed to divert water away from the foundation of the building and thus prevent water damage. Most gutters are fabricated on the construction site. This allows the gutters to be as long as needed (no seams) to fit the building. Assume you have 12 inch wide flat sheet metal to bend upwards to form right angles
