Rates: a comparison between units that we use to create proportions (set up cross multiplying).
Highlighting key words can help us create the proportions we use to solve problems.
- Rate Skills: cross multiply
- Lesson: Compare and Interpret Rates
Scale Drawings: use proportions (scale factors) to determine the size of the object in a drawing or in real life. We are finding a length or a width or a radius; a single dimension.

- Scale Factor Skills: Original and Answer Key
Scale Factors with Area questions: when two dimensions change size the total area changes by the product of the changes, the ratio for area, using 'k' as the scale factor, equals 'k squared'.
Build Your Skills
Scale Factors with Volume questions: when three dimensions change size the total area changes by the product of the three changes, the ratio for volume, using 'k' as the scale factor, equals 'k cubed'.

Similar Shapes :
- If all the dimensions are multiplied by the same scale factor, the drawing (model) is similar to the actual (real) figure.
- We can decide if drawings (models) are similar by determining the scale factor of all the dimensions.
