Week 20 of Classes: Wednesday, Feb 5

Hello APEX Families,
 
Here's the summary of classes today:
 
Algebra 1: We continued our unit on roots and discussed the order of operations, roots and powers being inverse operations, irrational numbers and how to determine their approximate value.
 
Homework: Assigned (see the homework post)
 
 
Precalculus/Trig: We discussed the remaining 4 trig functions, namely, tan, cot, csc, and sec and analyzed their graphs. We also looked at how functions can be combined by find composite functions, their products and sums and how that impacts the graphs of the resulting function.
 
Homework: Assigned (see the homework post)
 
 
Pre-algebra: We started a new chapter on combining multiple terms with x's.  Students also learned to set up equations for word problems related to rate of work and distances. 
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students did a great job, as always, selling different items at the school store. During class, we did the accounting for the store and then went over the homework related to finding down payments and monthly payments for new cars. Students noted the different used cars and their prices and we did a few calculations together to find the down payments and monthly payments for some of them
 
Homework: Assigned (see the homework post)
 
 
Problem of the Week #16: Problem of the Week #16 is posted today. Answers for last week's problems (POW #15) will be posted this Friday.
 
Thanks
Mrs. Narayanswamy

Week 20 of Classes: Monday, Feb 3rd

Hello APEX Families,
 
Here's the summary of classes today:
 
Algebra 1: We wrapped up the chapter on powers by learning to add, subtract, multiply and divide rational expressions with powers. We started a new chapter on roots and learned the basics of what roots mean.
 
Homework: To be assigned on Wednesday
 
 
Precalculus/Trig: We wrapped up the lesson on transformation of sinusoidal functions. Students also learned to draw graphs from the sinusoidal equations and write equations, if given the graphs.
 
Homework: To be assigned on Wednesday
 
 
Pre-algebra: Student learned to simplify algebraic equations before solving them. We started a new chapter on combining multiple terms with x's.  Students also learned to set up equations for word problems related to rate of work.
 
Homework: Assigned (see the homework post)

Solution to Puzzle Of The Week #14

Hello APEX families,
 
My apologies for posting the solutions to the logic puzzles a couple of days late!
 
Please check the attached file for the solutions.
 
The following students tried one or both the puzzles:
 
Alexa Schehrer 
James Schmeisser 
Owen Weekley
Quinn Kimmett
 
They ALL got any completed puzzles correct! Yay!! Kudos to them!!!
 
James Schmeisser won the raffle :-)  James, please stop by to pick a prize! Everyone else, stop by for a small treat! 
 
Thank you, as always, for trying these puzzles. Hope you had fun!

Week 19 of Classes: Wednesday, Jan 29

Dear APEX Families,
 
Here's the summary of classes today:
 
Algebra 1: Students took a short quiz on chapter 8. We reviewed scientific notation and then worked on simplifying fractions with powers.
 
Homework: Assigned (see the homework post)
 
 
Precalculus/Trig: Students took a short quiz on chapter 6. We then discussed transformation of sin and cos functions. Students learned vocabulary associated with this concept, namely, the amplitude, period, and frequency of periodic functions.
 
Homework: Assigned (see the homework post)
 
 
Pre-algebra: We reviewed solving 2 step equations, including equations involving addition, subtraction and division. Students learned to simplify algebraic equations before solving them. 
 
Homework: Assigned (see the homework post)
 
 
Consumer Math:  We started working on our new project on budgeting. Students got to pick their job, family scenario, their children's ages and their needs if applicable and an initial bank balance. They also noted all the possible new cars they can consider buying if they can afford it and we went over the computations needed to figure out the down payment, final price to pay and monthly payment for some of the cars.
 
Homework: Assigned (see the homework post)
 
 
Problem of the Week #15: Problem of the Week #15 is posted today. Answers for last week's problems (POW #14) will be posted this Friday.
 
Thanks
Mrs. Narayanswamy

Week 19 of Classes: Monday, Jan 27

Dear APEX Families,
 
Here's the summary of classes today:
 
Algebra 1: Students learned to do advanced distribution of terms containing exponents. They also learned to divide powers. Finally, we discussed how tiny numbers can be converted to scientific notation just as big numbers are.
 
Homework: To be assigned on Wednesday
 
 
Precalculus/Trig: We reviewed the concept of radians and learned to convert degree to radians. Students also learned to find lengths of arcs and linear speeds from angular speeds.
 
Homework: To be assigned on Wednesday
 
 
Pre-algebra: Students learned to write equations with multiple operations from words. They needed to pay attention to the order of operations in order to do so. They also learned to solve simple 2-step algebraic equations by undoing operations in reverse order of operations (SADMEP is a good mnemonic to remember this principle).
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: We went over the homework related to reconciling transaction registers so that students can confirm if they did it  accurately. We started a new project on budgeting. Students got to pick their job, family scenario, their children's ages and their needs if applicable and an initial bank balance. They also noted all the possible new cars they can consider buying if they can afford it!
 
Homework: Assigned (see the homework post)
 
 
Problem of the Week #15: Problem of the Week #15 is posted today. Answers for last week's problems (POW #14) will be posted this Friday.

Week 18 of Classes: Monday, Jan 20

Dear APEX Families,
