#### Course Description

Upgrade of computational skills required in the landscape industry. Range of topics include business, construction, materials, measurement, water hydraulics, chemicals and fertilizers. Prerequisites: MTH 20. Recommended: MTH 60. Audit available.#### Addendum to Course Description

This course applies math concepts directly to real life problems encountered in the landscape industry. It works for both student's reviewing or updating skills and for students who have to learn skills in preparation for other classes or employment in the landscape industry.

#### Intended Outcomes for the course

Students completing this class will be able to:

• recognize, interpret, formulate and apply real world math situations to their professional/technical field.

• prepare for further course work.

#### Outcome Assessment Strategies

• At least 3 in-class examinations (two using the scientific calculator)

• At least 1 material take-off project (architect's and/or engineer's scale required)

• At least one of the following additional measures:

- Take-home examination

- Graded homework

- Individual project

- In class activities

- Attendance

- Individual student conference

#### Course Content (Themes, Concepts, Issues and Skills)

Themes, Concepts and Issues:

1. Understand irrigation systems by interpreting/interpolating graphs needed for computing pressure losses and working pressure.

2. Apply scaling and trigonometry functions to landscape design and site survey situations.

3. Interpret/calculate pesticide formulations for application within the state licensing laws and for protection of our environment.

4. Estimate materials and costs for landscape construction.
