What are examples of units of Measurement? ◦ Inch, foot, centimeter, degree, tablespoon, cup, miles, etc. Why are they important? ◦ Measurements are all around us. They provide standards and stability to every day life.
3
What does this mean? ◦ Accuracy is how close to “true” measurements are. Why is it important? ◦ Accuracy is important because the exactness of the measurements affects the product and results of the experiment or project you are working on. Ex: Installing a carpet. If you measure the carpet and floor incorrectly you will end up with either too little or too much of the carpet.

1. Choose the correct formula for the shape and what you’re trying to find. 2. Plug the known values into the equation and solve for the unknown variable. 3.Use correct units: Perimeter uses just the unit Ex: cm, m, ft, mi Area uses the unit squared Ex: cm^2, m^2 Volume uses the unit cubed Ex: cm^3
