Learning Goal:
We are learning to apply proportional reasoning and problem solving to similar triangles


Warm up: Which One Doesn’t Belong?

*For each set of 4 pictures, find a reason why each one doesn’t belong… For example, last week we looked at this set:

wodb-numbers

We decided that 9 doesn’t belong because it only has one digit (it is also the only one whose digits don’t add to 7), 16 doesn’t belong because it is an even number, 43 doesn’t belong because it is not divisible (i.e. a prime number), and 25 doesn’t belong because all the others have a digit that is divisible by 3.

Now, try a shape example here.

Next, you will write a quiz about proportional reasoning. you can use a calculator. Hand in.

Finally, we will look at how to solve word problems that involve similar triangles. Read over the note. Practice using the textbook questions onĀ PG 33-35 #5, 7, 12.

You can also finish any questions from the previous class.
