Homework - Assignments should be done!

Assignment 2: look through magazines and find one example of a scale diagram. Cut the item out and tape it to a piece of grid paper. Remember: you only need to worry about the outline of the item, not the detail in the picture.

a) Enlarge to scale of your choice (for example 2.3)
b) Reduce to scale of your choice (for example 0.67)
c) Draw your item to scale


Assignment 3
Find one shape, cut it out and copy it on grid paper.

Show an example of each of the following:

1) rotation 2) reflection 3) translation 4) enlargement



All assignments can be completed in class with the time allotted! However, if you are not done, complete for homework.

Wednesday

Hi students of Math 9 - I hope your exams are going well and you are doing the best you can do and that you are giving every effort to your studies. Tomorrow is your Math exam. Please have two pencils, an eraser, your calculator, and your "risk button" pushed in. Try every question, think about you are doing and show your work. Believe in yourself as much as I believe in you! If you have done your work and practiced, you will do fine.
