Today we began our study of statistics with a review of dot plots, histograms, and box and whisker plots.

Please complete the Problem Set from Lesson 2 tonight for homework, focusing on the differences between Median and Mean.

Today we began our study of statistics with a review of dot plots, histograms, and box and whisker plots.

Please complete the Problem Set from Lesson 2 tonight for homework, focusing on the differences between Median and Mean.

Today we spent time in class reviewing the relationships between the graphs, tables, and equations associated with parabolas.

Please complete the review page tonight for homework.

Today in class we reviewed how to use the quadratic formula, and where students make the most common mistakes.

We also introduced “The Discriminant” which we will study in more depth tomorrow.

Please complete EXERCISES 1 – 5 beginning on page S78 tonight for homework.

As we wrap up completing the square, here is a great refresher on Projectile Motion. Everything we learned this week in class should only make that problem easier!

Have a great weekend.

First of all, I want to make something VERY, VERY clear. You do not always need to use completing the square when solving a quadratic equation. If you can factor it, that is A LOT easier. If you can solve it with square roots, that is also A LOT easier.

Completing The Square is something you should only use when no other options are available.

**Think about that when solving problems 28 – 33 on page 674.** (Even though these problems are from the next section, all of them can be solved using one of the methods mentioned above.)

**Then go back to page 667 and solve problems 28, 30, 33, 36, and 37 using completing the square.**

Towards the end of class today, we used what we know about completing the square in order to solve equations.

Don’t forget to include the plus/minus symbol when necessary!

Tonight, please complete EXERCISES 1 through 4 tonight for homework.

Here is the packet from Lesson 12: Lesson 12 – M4

Please complete the Problem Set 1 – 5 over the weekend.

Today in class, Kyle reminded us of an important lesson: **The shape of a graph is not necessarily the path of the object.**

Then Bibi, Kevin, and Ari showed us how to identify key features of parabolas in a table.

Please complete the entire problem set tonight for homework, beginning on page S59.

Today in class we began to study how we can use everything we know about parabolas and extend it into a real world study of Projectile Motion.

A projectile (by definition) can not create its own lift or thrust.

If I throw a marker, the marker becomes a projectile.

If I throw a paper airplane, it is not a projectile.

Please complete and analyze #2 from the Problem Set tonight for homework.

Class will meet for 20 minutes tomorrow.

**Please return your signed permission slip to school on Monday. If you need to print another copy, click on the Parent Release Letter.**

Engage NY writes the literal equation of parabolas in factored form as:

f(x) = a(x – m)(x – n)

The notation really doesn’t matter, as long as you understand the importance of each part of the equation: a, m, and n.

Whenever you complete a graph, always label the key features. This includes: the y-intercept, x-intercept(s), and axis of symmetry.

Please complete Number 1 on the Problem Set on page S54. You should bring 5 graphs to school on Monday for parts a through e.
