Week 9 of Classes: Friday, Oct 25

Dear Apex Families,
 
Here's the summary of classes and homework assigned for this week:
 
Geometry: Students learned what one-on-one correspondence means when it comes to two triangles being congruent. We learned the first of several shortcuts, namely Side-Angle-Side Postulate (aka SAS) to prove congruence of triangles. Students took a few minutes to work on some problems independently. 
 
Homework: Assigned (see the homework post)
 
 
Algebra 2: We continued our discussion quadratic equations. Students learned to set up equations for border problems. They also learned the "ac" technique and completing the square technique to solve quadratic equations.
 
Homework: Assigned (see the homework post)
 
 
Pre-algebra: Student took the 6s multiplication facts quiz. We wrapped up the unit on percents by considering techniques to determine the percent when a ratio/fraction is given. We tied this concept to how grades are determined by teachers in terms of percents. We started a new unit on measurements. We discussed different units of length in the US customary system such as inches, feet, yards and miles and how to convert from one to the other. The basic technique of dimensional analysis was covered.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students came in during recess to conduct survey for the elementary and high school students. They will conduct the survey for middle school students next week. We put this data into our Google sheet during the class. Students voted on a good name for their school store and decided on a fun one - I'm Happy When I see Yo Money!  
 
Homework: None
 
 
Puzzle Of The Week: 8th Puzzle posted! Solutions are due next Friday. Solution to last week's puzzle will be posted today.
 
Thanks!

Week 9 of Classes: Thursday, Oct 24

Dear Apex Families,
 
Here's the summary of classes and homework assigned for this week:
 
Geometry: We focused on triangles and proved that the interior angles of a triangle add up to 180 deg and the exterior angle of a triangle is always equal to the sum of the two remote interior angles of a triangle. 
 
Homework: To be assigned on Friday
 
 
Algebra 2: We started a new unit on quadratic equations. We learned to solve them by undoing and factoring using reverse distribution and advanced reverse distribution.
 
Homework: To be assigned on Friday
 
 
Pre-algebra: Student took the 6s multiplication facts quiz. We started a new unit on measurements. We discussed different units of length in the English/Common system such as inches, feet, yards and miles and how to convert from one to the other. We also learned to use a unit conversion table to convert units from one to the other.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students came in during recess to conduct survey for the elementary and high school students. We put this data into our Google sheet during the class. Students voted on a good name for their school store and decided on an awesome one - The Pack Got Your Snacks!  Students continued their activity on coupons to save money as they planned a meal for their family. They will complete it next week.
 
Homework: None

Week 8 of Classes: Friday Oct 18

Dear Apex Families,
 
Here's the summary of classes and homework assigned for this week:
 
Geometry: We reviewed briefly what polygons are. Students learned about the different types of triangles, classified based on lengths of sides and measures of angles. Students worked either independently or with a partner on packet of practice problems focused primarily on different types of angles we have learned so far. We will continue working on these problems next week after we complete a few of the lessons.
 
Homework: Assigned (see the homework post)
 
 
Algebra 2: We continued our discussion of radicals. Students learned to rationalize denominators. We also discussed how roots are fractional exponents and we can go back and forth between powers and roots. Students worked briefly on a packet of advanced algebra 2 problems related to fractional expressions involving x's, powers and roots.
 
Homework: Assigned (see the homework post)
 
 
Pre-algebra: Students took the 0s-5s multiplication facts quiz. We focused on percents again. We considered percents of different types such as fractional percents and decimal percents and found percents of different numbers. We specifically considered how percents are used in banking and talked about compound interest (finding interest on the principal amount as well as the interest already paid by the bank). 
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students short-listed the items they want to sell and entered the information into a survey that they plan to give next week to the APEX student body. 
 
Homework: Think of 3 possible names for your school store and write them down. Bring the list to class next week to share with your peers.
 
 
Puzzle Of The Week: 7th Puzzle posted! Solutions are due next Friday. Solution to last week's puzzle will be posted today.
 
Have a great weekend!

Week 8 of Classes: Thursday, Oct 17

Dear Apex Families,
 
Here's the summary of classes and homework assigned for this week:
 
Geometry: Students learned about converse statements and how they are not always true even if the original statements are true. We found (either as a postulate or by proving as a theorem) that if alternate interior angles, alternate exterior angles and corresponding angles are congruent or interior angles on the same side of the transversal are supplementary, then the lines involved are always parallel. We started a new chapter on triangles. We discussed what polygons are and how triangles are the simplest of all polygons.
 
Homework:  To be assigned on Friday
 
 
Algebra 2: We continued our discussion of radicals. Students learned to add and subtract like radicals, distribute radicals over an expression, and simplify radicals. We started talking about how radicals fractions are rationalized.
 
Homework:  To be assigned on Friday
 
 
Pre-algebra: Students took the 0s-5s multiplication facts quiz. We focused on percents again. We considered percents of different types such as fractional percents and decimal percents. We specifically considered how percents are used in banking and talked about compound interest (finding interest on the principal amount as well as the interest already paid by the bank). Students also learned how to determine percents if we are considering a fraction of something. In addition, we briefly talked about how points in tests can be converted into percents.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: Students short-listed the items they want to sell and entered the information into a survey that they plan to give next week to the APEX student body. We started a short new activity about using coupons to save money by using grocery flyers to buy ingredients and cook a meal for the family within a limited budget.
 
Homework: Think of 3 possible names for your school store and write them down. Bring the list to class next week to share with your peers.
 
 
Puzzle Of The Week: 7th Puzzle posted! Solutions are due next Wednesday. Solution to last week's puzzle will be posted on Friday.
 
Have a great weekend!

Week 7 of Classes: Friday Oct 11

Dear APEX Families,
 
Here's a summary of classes today and homework assigned for this week:
 
Geometry: We proved that if lines are parallel and cut by a transversal, the interior angles on the same side of the transversal are supplementary. Students learned how the Greeks figured out the circumference of the earth by using corresponding angles. We spent the last 15 minutes setting algebraic equations for word problems involving complementary and supplementary angles and solving them.
 
Homework: Assigned (see the homework post)
 
Algebra 2: We wrapped up our chapter on powers and fractional expressions involving them and started a new chapter on radicals.
 
Homework: Assigned (see the homework post)
 
 
Pre-algebra: Students took the 4s multiplication facts quiz. We wrapped up the unit on decimals by learning to multiply and divide decimals, convert fractions to decimals by dividing, and got introduced to non-terminating, repeating decimals. We started a new unit on percents.
 
Homework: Assigned (see the homework post)
 
 
Consumer Math: We wrapped up our activity of shopping spree. We started our discussion of setting a school store by brainstorming the different items we want to sell.
 
Homework: None

Week 7 of classes

Dear APEX Families,
 
Here's a summary of classes today and homework assigned for this week:
 
Geometry: We solved a few homework problems together that some of the students had questions about. We then continued our discussion of parallel lines. We talked about or proved that when lines are parallel and cut by a transversal, a variety of angle pairs (alternate interior, corresponding, alternate exterior) become congruent and interior angles on the same side of transversal become supplementary. More about them tomorrow!
 
Homework: To be assigned tomorrow
 
Algebra 2: We continued our discussion of rational expressions with higher degree exponents. We learned to add, subtract, multiply and divide them. We also reviewed scientific notation and how to manipulate them.
 
Homework: To be assigned tomorrow
 
 
Pre-algebra: Students took the 4s multiplication facts quiz. We wrapped up the unit on decimals by learning to convert fractions to decimals by dividing, and got introduced to non-terminating, repeating decimals. We started a new unit on percents.
