InCA Assignment for 11/12

Your Unit 2 test is on Thursday, November 14. We played a review game in class today, and tomorrow will be some time to work independently on review. We will also have a Homework Quiz tomorrow.

InCA Assignment for 11/8

We did some more review with solving rational equations today, focusing especially on dealing with equations that require us to factor denominators to find a common denominator.

We did some more practice with simplifying complex fractions today with a fun activity (or I hope it was!). We will have a quiz on complex fractions and operations with rational expressions in general on Tuesday, November 5. Your homework tonight is the first quiz review sheet.

Intro to College Algebra Assignment for 10/30

We’ve moved on to the next phase of the rational expressions unit: Complex Fractions. Don’t be intimidated by their name! These are expressions that involve “nested fractions,” meaning the numerator and denominator of the expression are both fractions (or a sum/difference of fractions) themselves.

Remember the basic process for simplifying these beastly expressions:

  1. Combine fractions in the numerator (finding a lowest common denominator and so on) so you have one single rational expression
  2. Combine fractions in the denominator (LCD, etc.)
  3. Keep the top fraction, flip the bottom fraction, and change the operation to multiplication (KFC)
  4. Simplify.

I have some ideas of how homework accountability might change for our class. Please complete this Google Survey about homework. The survey is completely anonymous. Please be honest!


For Period 3

We spent today practicing adding, subtracting, multiplying, and dividing with an IXL assignment. Your homework is one of two:


For Period 8

We did some more work with adding/subtracting rational expressions today, this time with polynomial denominators. The key thing to remember with these is that we can only obtain a common denominator through multiplying. We cannot add/subtract denominators. See the notes and the video below for examples.

For Period 3

We worked with adding and subtracting rational expressions today, modifying the usual “lowest common denominator” process to accommodate monomial denominators. We’ll do some more practice with this on Monday.

Intro to College Algebra Assignment for 10/15

We started a jigsaw activity in class today, exploring the multiplication and division of rational expressions. You started out in groups examining three carefully worked out simplification, multiplication, and division problems. In step 2, you were given some additional examples of that same type of problem to complete in your groups. Step 3 will be to share what you’ve observed with some new people.

We didn’t quite get to finish Step 2 in class, so your homework is to do that on your own. Finish whatever problems you were working on in class. If you weren’t in class, take your pick of which type of problem to analyze and come to class tomorrow prepared to share.

InCA Assignment for 10/11

Today in class, we started with a Desmos activity exploring the similarity of reducing numeric fractions and simplifying rational expressions. They both involve factoring, then reducing the common factors away.
