My Students

Students from our school have a variety of economic backgrounds with nearly 60% receiving free or reduced lunch. The school population is approximately 35% minority, with about 50 ELL students. Our school is the largest of four high schools in our district with 1,700 students.

Our students have been involved in a variety of engineering challenges, including FIRST Tech Challenge (FTC) and FIRST Robotics Competition (FRC).

The students on our FTC teams spend a significant time volunteering and giving back to the local community.

My Project

Students will use a sine bar and gage blocks for laying out angles on metal projects that will be machined manually or with a CNC (Computer Numerical Control).

This donation of tools will allow my students to apply mathematics to a real-world problem and see how mathematics is used in the world of Advanced Manufacturing.

Not only will they learn about it, but they will also apply it for projects that they create.

Students will also use other precision layout tools to create a counterbore in a project. The students will learn about drilling clearance holes, counterbores, countersinks, as well as selecting the proper drill bit to drill and tap (put threads in) a hole.
