Week 15 of Classes: Thursday, Dec 12

Hello APEX families,
 
Here's the summary of classes today:
 
Geometry: We continued our discussion of quadrilaterals. We learned about trapezoids and a little bit about parallelograms. 
 
See you tomorrow for the finals!
 
Homework: To be posted on Friday
 
 
Algebra 2: We continued our discussion about linear equations. Students learned to distinguish between two forms, namely point slope form and slope intercept form. They also learned about direct and inverse variations.
 
See you tomorrow for the finals!
 
Homework: To be posted on Friday
 
 
Pre-algebra: We continued our unit on integers. Students shared a few real-world examples of when negative numbers are used. We learned rules to add, subtract, multiply and divide integers.
 
Homework and Final Exam: Assigned (see the homework post. Parents, please read the notes for you regarding the finals. Thanks!)
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students did a great job selling items at the school store during lunch. In class, we did the accounting for the same. Then, we reviewed simple interest and compound interest and retried some of practice problems from the homework assigned last week so that all students are clear about both types of interests.
 
Homework: None

Solution to Puzzle Of The Week #12

Hello Apex Students,
 
The solution to the 12th puzzle is attached. Unfortunately no one got the solution right. We will try a few other statistical puzzles next year to get a chance to explore this area of math more.
 
Students who submitted a solution, good job trying! Please stop by for a treat :-)
 
Have a great weekend!
 
Mrs. Narayanswamy

Week 14 of Classes: Thursday, Dec 5

Hello APEX families,
 
Hope you had a wonderful Thanksgiving and got some time to relax and rejuvenate!
 
We are now in the last leg of this semester and very busy completing content in several subject areas.
 
Please note that next week our school store will be open during lunch break. So, please remember to bring some money if you would like to shop with us.
 
Here's the summary of classes today:
 
Geometry: Students learned of four different logic statement: An original conditional statement, its converse, inverse and its contrapositive statement. We also started talking about an important theorem regarding unequal sides and unequal angles in triangles. More about it tomorrow!!
 
Homework: To be posted on Friday
 
 
Algebra 2: We reviewed synthetic division. We started a new chapter on first degree two-variable equations. Students learned about representing relations between two quantities using a table or an equation. We learned to solve one variable in terms of another.
 
NOTE: The following problems may be skipped in the extra practice problems assigned before the break (worksheet labeled AA2 Chapter 1 review) - 3) e, g, h, i, j, k; 4 b); 5 a), b); 
 
Homework: To be posted on Friday
 
 
Pre-algebra: Student took the 12s multiplication facts quiz. We reviewed how to algebraic equations with multiplication and division using algebraic symbols we had learned last week for these operations. We also learned to set algebraic equations to solve word problems involving percents, distance, speed and time. We started a new unit on integers and reviewed negative numbers and how to represent them on a number line.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students reviewed the concept of interest when saving money in a bank. We specifically reviewed simple interest and how to compute it using a formula. Students watched 4 short videos about important concepts in saving money, namely, start saving early, invest more, get a higher interest rate, get compound interest rather than simple interest and that higher the return from interest, higher the risk. We briefly talked about investing in stocks and how the concept of higher returns, higher the risks, plays out in the stock market. Students learned the formula for computing compound interest and how it is a better option than simple interest.
 
Homework: Assigned (see the homework post)
 
Puzzle Of The Week: We are taking a break from solving puzzles as all secondary math classes are getting busy preparing for final exams next week. Look forward to solving more puzzles in the new year!
 
Thanks
Mrs. Narayanswamy

Week 13 of Classes: Thursday, Nov 21

Hello All,
 
Please note that there are no classes next week. Enjoy your Thanksgiving break!
 
Parents, please check Infinite Campus. All pending work and test corrections should be submitted the week students return (Dec 2-6). No late work will be accepted past that.
 
Here's the summary of classes today:
 
Geometry: We started a new unit on inequalities and learned the different properties of inequalities. We also discussed the triangle inequality postulate.
 
Homework: To be posted on Friday
 
 
Algebra 2: We continued our discussion of  higher degree equations. Students learned the polynomial division to factor a polynomial. They also learned about how to find at least one rational solution to a polynomial by using the Rational Zeros Theorem.
 
Homework: To be posted on Friday
 
 
Pre-algebra:
Students took the 11s multiplication facts quiz. We reviewed how to use the inverse operations and the Golden Rule of Algebra to solve simple algebraic problems. Students also learned how multiplication and division is shown in algebra using a dot, parentheses or just pushing the number and x together for multiplication and the fraction bar for division in place of the traditional symbols for the two operations. We briefly discussed how percent problems can be solved algebraically as well.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students did a great job of setting up the school store and having a successful 1/2 hr of selling different items during lunch. Good work all! We did the accounting for the store during class time. We decided on what changes to make for next time the store is set up. We then talked about types of household expenses and how to classify them. We also started talking about saving money in banks and the concept of interest. We focused on what simple interest is and how it's calculated. After the break, we will talk about compound interest.
 
Homework: Assigned (see the homework post)
 
Puzzle Of The Week: 12th Puzzle posted! Solutions are due in 2 weeks. Solution to last week's puzzle will be posted on Friday.

Week 11 of Classes: Thursday, Nov 7

Hello APEX families!
 
We are a week into November now - can you believe that?!! As the weeks are flying by, we are immersed in all kinds of math in our classroom. Here's a summary of what we did today:
 
Geometry: Students learned to use the concept of CPCTC (Corresponding Parts of Congruent Triangles are Congruent) to prove sides and angles of triangles are congruent or that line segments are angle or segment bisectors.
 
Homework: To be posted on Friday
 
 
Algebra 2: We wrapped up our unit on radical equations and started a new chapter on imaginary and complex numbers. Students got an introduction to the imaginary i and how to add, subtract and multiply imaginary numbers. More to come tomorrow!
 
Homework: To be posted on Friday
 
 
Pre-algebra: Student took the 8s multiplication facts quiz. We continued our discussion of unit systems. We discussed units for area in both systems and learned that we should divide or multiply by the conversion factor twice to go from one unit to another. We also discussed what volume meant and learned to convert units of volume of shapes by multiplying or dividing by the conversion factor three times.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: We made a short list of items to start selling in 2 weeks. Students completed their store posters and we put most of them together on a poster board. We also reviewed the homework problems to make sure students are understanding the math behind computing taxes, discounts and tips.
