Introduction
Have you ever made a "To Do" list?
If you have, you know that having a picture list lets you see what you must do on one sheet of paper. Even if you have not, you know that a to do list is a shortened version of things that you need to accomplish, at a glance. A to do list also helps you prioritize tasks.
A blueprint or project drawing is the same thing. It lets all concerned see what must be done and how the pieces of a project are interrelated.
Following successful completion of this lesson, students will be able to...
- Convert between measurements given in customary or metric systems of measurement.
- Calculate measurements for blueprints and drawings and determine dimensions by scaling.
- Convert decimals to fractions, and fractions to decimals to interpret blueprints and measuring materials.
- Identify various tools of measurement.
- Use proportions to solve applied problems.
- Demonstrate an understanding of blueprints and drawings. Draw a blueprint to scale.
Essential Questions
- How can ratios and proportions generate accurate measurements?
- What is scale?
- What is the relationship between dimensions (length, width, and/or height) in two- and three-dimensional objects?
- How does a change in one dimension affect the other dimension(s)?
- How can technology be used to compare mathematical solutions?
Enduring Understandings
- Geometric and measurement principles can be used to define and explain our physical world.
