### PRODUCT DESCRIPTION

This is an excerpt from Amazon's popular line of Bossy Brocci Math and Big Science workbooks! [it's pronounced like "Brawsee"]

Printing should be done in Landscape and DOUBLE-SIDED, with the flip being along the 'SHORT' side.

================================================

Note: If you want your students to use an actual Coordinate Plane to determine Enlargements, Reductions, Coordinates and Scale Factors . . . then please consider Transformation Lessons 17 through 20.

Students will:

1) Calculate and Write 10 Scale Factors, given both Original & Dilation Ordered Pair Coordinates
2) Label Missing Image Points
3) Test 16 pairs of Ordered Pair Ratios for Proportionality, via executing and writing-in Cross-Products
4) Comprehend that Scale Factor is just a Proportionality Constant
5) Identify which 4 ratios of the 16 are equivalent to the mathematical definition of Scale Factor, and equal to the actual Dilation from Steps 1 and 2
6) Be compelled to show their work in a neat & orderly format
7) Be trained to Understand and Manipulate Scale Factors methodically & systematically

Printing should be done in Landscape and double-sided, with the flip being along the 'short' side
