Week 5 – Precalculus 11

This week in Precalculus we started a new unit! Solving Quadratic Equations. We primarily focused on review and factoring Binomials and Trinomials. I enjoyed this last year, so I liked this week. Of course it was not the same as last year, but I learned and revisited the idea / synonym; CDPEU and that is what I am going to be talking about in this Blog Post! I will provide a silly sentence to remember this trick and an expression to go with each letter! So far, this helpful hint has been used in almost everything we have done. Enjoy 🙂

Week 3 – Precalculus 11

This week was short. Monday we had our test for Sequences and Series, Tuesday we had a snow day, Wednesday we started review on Roots and Radicals with a new element of Absolute Value and today we continued with those ideas and completed the Checkpoint questions. This week was pretty low-key. What I will be highlighting in my ShowMe, was what I struggled with most – When there is a fraction under a root sign. I enjoy attaching ShowMe’s as it allows my viewers to see the specific steps, along with hearing my voice; It has most learning styles included! Hopefully it works for you. As I said, you will be watching how to solve for a fraction being placed under a root sign, some mixed and entire radicals, along with a question or two of solving for an Absolute Value. 

Week 2 – Precalculus 11

This week wrapped up our first unit! It was generally based around Geometric Sequences and Series. For myself, it was a step higher from Arithmetic Sequences and Series and slightly more challenging. Due to formulas, solving the questions in the workbook came with ease… except word problems. Therefore, I thought I would demo one for my Blogpost this week!

Week 9 Math 10

Week 9 Math 10….


This week we finished up polynomial expressions and began Factoring polynomials. There are different ways to find the answer to a polynomial expression.

If your expression was:

 

 

 

 

 

 

Then one of the many ways you can solve the answer is using an area model. This is a faster way to find a answer then using tiling models.Here how you would set it up:

In black I have show the expression.

In orange is the area  model diagram. 

In pink is your answers for going left and top. Each time.

 

Therefore your answer is in the pink.
