Homework for Spring Break: Friday

Hello APEX students and families,
 
I hope you are all staying safe and healthy. These past few days have seen some dramatic changes in our day-to-day lives and in our community that can feel overwhelming. I hope you get to spend some relaxed time together at home during this break.
 
Given the current circumstances, we are missing two Fridays of instruction time. I am posting homework for all math classes that include reading some extra lessons and doing some math related to these lessons. We will positively connect after the break and will continue our classes based on decisions that the district makes. 
 
Parents, if your student completed all homework that was due on Friday, please send me a quick email verifying the same. If students took chapter tests, kindly take pictures of the completed test and all their work and send them to me via email over the next couple of days so I can grade them during this break.
 
In the meantime, hope you all stay safe and healthy.
 
Thank you
Usha Narayanswamy

Updates on Monday

Hello Families,
 
The last 24 hours have changed so much in our community and of a sudden, we have 2 weeks of spring break!
 
I would like all my students (including my Friday students) to get some rest and relax and not worry about their classes with me! I will send updates (including any homework for the core math classes) beginning of next week.
 
Have a good weekend!
 
Mrs. Narayanswamy

Week 25 of Classes: Thursday, Mar 12

Dear APEX Families,
 
Here's the summary of classes today:
 
Geometry: We started by trying a few trigonometric word problems. We then continued our unit on circles. Students learned two important properties of chords in a circle. We then discussed how a radius of a circle drawn to a tangent at the point of tangency is always perpendicular to it.
 
Homework: To be assigned on Friday
 
 
Algebra 2: We continued our discussion of quadratic inequalities. Then students learned to solve inequalities with 2 variables.
 
Homework: To be assigned on Friday
 
 
Pre-algebra: We started a new unit on geometry. Students learned about several vocabulary terms. such as points, lines, line segments, planes, parallel, intersecting and skew lines, angles, and different types of angles. Students also learned to measure angles using a protractor. In addition, students learned about different types of pairs of angles such as adjacent angles, vertical angles, complementary and supplementary angles.

Homework: Assigned (see the homework post)
 
 
Consumer Math: Students did a great job of selling various items in the school store.  We did the accounting for the store during class and then students worked on a projected budget for their "Life" simulation.
 
Homework: None except any pending class work from the past 2 weeks need to be complete as we start to tie together all the elements of our budgeting project.
 
 
Problem of the Week #21: Problem of the Week #21 is posted today. Answers for last week's problems (POW #20) will be posted this Friday.
 
Thanks
Mrs. Narayanswamy
 

Week 24 of Classes: Friday, March 6

Dear APEX Families,
 
Here's the summary of classes today:
 
Geometry: Students took a quiz. We started a new unit on circles and talked about basic vocabulary related to circles.
 
Homework: Assigned (see the homework post)
 
 
Algebra 2: Students took a quiz. We discussed simple quadratic inequalities.
 
Homework: Assigned (see the homework post)
 
 
Pre-algebra: We reviewed the concepts we have learned about powers so far. We then wrapped up our chapter on powers and roots by learning about division of powers, simplifying fractions with powers, introducing the concept of roots and how roots and powers undo each other and two special exponents, namely an exponent of 1 and 0.

Homework: Assigned (see the homework post)
 
 
Consumer Math: Students completed their grocery list for the month and many students figured out the total amount they will be spending on grocery. 
 
Homework: None except for those who need to complete their class work.
 
 
Problem of the Week #20: Problem of the Week #20 is posted today. Answers for last week's problems (POW #19) will be posted by tonight.
 
Thanks
Mrs. Narayanswamy

Week 24 of Classes: Thursday, Mar 5

Dear APEX Families,
 
Here's the summary of classes today:
 
Geometry: We reviewed the basics of trigonometry we had learned last week, namely, the three trig ratios, sin, cos and tan. Students learned how the Greeks used trig to calculate distances between Earth and other celestial bodies. We did several practice problems related to these concepts as well as review problems.
 
Homework: To be assigned on Friday
 
 
Algebra 2: We started a new unit on inequalities. We reviewed the basics of inequalities and how algebraic inequalities with a single variable and first degree can be solved as well as graphed. Students learned about compound inequalities as well.
 
Homework: To be assigned on Friday
 
 
Pre-algebra: Student took a multiplication quiz. We wrapped up our chapter on powers and roots by simplifying fractions with powers, introducing the concept of roots and how roots and powers undo each other and two special exponents, namely an exponent of 1 and 0.

Homework: Assigned (see the homework post)
 
 
Consumer Math: Students completed their grocery list for the month and many students figured out the total amount they will be spending on grocery. We went over some other costs to consider such as rent, utilities, car insurance, etc.
 
Homework: None except for those who need to complete their class work.
 
 
Problem of the Week #20: Problem of the Week #20 is posted today. Answers for last week's problems (POW #19) will be posted this Friday.

Week 23 of Classes: Friday, Feb 28

Dear APEX Families,
 
Here's the summary of classes today:
 
Geometry: We reviewed relationship between sides of the isosceles right triangles (45-45-90 deg triangles) as well as the 30-60-90 degree triangles. Students were introduced to the basics of trigonometry in relation to similar triangles. Students learned about the 3 main trig ratios, namely, tangent (tan), sine (sin) and cosine (cos). 
 
Homework: Assigned (See homework post)
 
 
Algebra 2: We continued our discussion of systems of equations. We solved a system of 2nd degree equations with 2 variables. We also learned to solve linear equations with 3 variables using elimination and substitution methods. Students got a mini lesson on determinants and how to use them to solve 2-variable linear equations.
 
Homework: Assigned (See homework post)
 
 
Pre-algebra: We continued our unit on powers. Students learned  about scientific notation, the place of powers in the order of operations and we tried several computing problems to understand this order of operations. Students learned to add, subtract and multiply powers.

Homework: Assigned (See homework post)
 
 
Consumer Math: Students primarily shopped online using their grocery list.
 
Homework: Complete the online shopping at home and bring the filled-in grocery list with prices next week
 
Problem of the Week #19: Problem of the Week #19 is posted today. Answers for last week's problems (POW #18) will be posted by tonight.
 
Have a great weekend!
 
Thanks

Week 23 of Classes: Thursday, Feb 27

Dear APEX Families,
 
Here's the summary of classes today:
 
Geometry: We worked on a couple of problems students had questions about from their homework and then continued our unit on right triangles and trig. Students learned of the special relationship between sides of the isosceles right triangles (45-45-90 deg triangles) as well as the 30-60-90 degree triangles.
 
Homework: To be assigned on Friday
 
 
Algebra 2: We continued our unit on systems of equations. Students learned to solve systems of linear equations using graphs besides the algebraic methods they had learned last week. We also discussed and then solved systems of equations with higher degree (primarily 2nd degree systems of equations)
 
Homework: To be assigned on Friday
 
 
Pre-algebra: We continued our unit on powers. Students learned the place of powers in the order of operations and we tried several computing problems to understand this order of operations. Students learned to add, subtract, multiply and divide powers.

Homework: Assigned (see the homework post)
 
 
Consumer Math: Students worked on creating their grocery list from the menu they had created for 2 weeks. Some students found time to go online to shop using their grocery list.
 
Homework: None except completing any unfinished grocery list at home.
