Several of the practice suggestions are from iXL – I just learned about this at a math leadership meeting this week as well as it was suggested by a couple of parents on Friday (THANK YOU!).  You may do up to 20 practice problems per day without having an iXL account.

When a problem is incorrect, it gives the correct answer AND an explanation/practice for you to “get it”.  I see this site a great benefit to use throughout a unit of study.

For most topics, I have linked to the Open Math Reference site which offers not only text but also interactive examples of each.


Classifying Triangles – Sides, Angles

Interior Angle Sum

Exterior Angles

iXL practice on the above go here  and see F1, F2, F3

Using Converse of Pythagorean Theorem to Classify Triangles  (Triangle Type Quiz

iXL practice see Q1, Q2, Q3

Triangle Inequality

Relationships sides / angle

Isosceles Triangles

Equilateral Triangles

Special Lines/Segments of Trianlges:

Midsegment of Triangle

Medians, Angle Bisectors, Altitudes, Perpendicular Bisectors

iXL practice on the above see M1, M2, M3

Triangle Centers

Triangle Congruence –  Triangles are congruent if you can slide them around, rotate them, and
flip them over in various ways but can “pile” on top of one another.

AAS – if 2 angles are known to be congruent in a triangles and a side OPPOSITE one of those angles is congruent.
HL – MUST know the triangle is a right triangle
SSA – the one that shall not be named…does not guarantee congruence!
AAA – does not guarantee congruence but does prove similarity,

Algebra 2 9/18/12

Monday 9/17/12 Flashbacks for this week…I can solve absolute value equations.  Quiz Friday

Monday 9/17/12 INB page 23 – Summary of Explore Activity last Wednesday.  And INB page 22 assignment.


Tuesday 9/18/12 – Assessment over Relations/Functions – Students not achieving at least 85% will be required to retake AFTER they have completed a wrong answer analysis and practiced / proof of study.


Due Thursday – If you didn’t know what to do…pretend you do and do it.  Students are asked to look for clues in the 5 given problems and attempt to do them.  These are to be attempted before you walk in class on Thursday.
Thursday – Function Operations
I can add, subtract, multiply functions. 
I can create a new function by finding the composition of 2 given functions.
Friday – Flashbacks Quiz – Solving Absolute Value Equations
Friday – Wrong Answer Analysis on Tuesday’s (9/18) Assessment

Midsegment Investigation– completed by Wednesday – if you are not recognizing any patterns in the chart – please go back and check your slope & distance calculations!  Some silly mistakes  can cause all of your conclusions to be incorrect~!

Algebra 2 – Transforming Function Graphs 9/11/12

Skills Quiz Wednesday on Finding Inverses of Functions using Equations.

Flashbacks for this week: (Quiz Friday!)

Began investigation on transforming functions – How can changing part of the equation change the graph?

Students were assigned to a blue, red or yellow group. 

Work individually to record patterns/changes they see in the graphs.

Students may use an online graphing calculator to complete.  For radical type sqrt(x) and absolute value abs(x).

Pair & Share – to ensure correct patterns were recognized.

Within groups of 3 (blue, red & yellow) – compare and contrast the transformations – considering different function families.

Our Friday ACT-Skills Quiz over Inequalities:


Pages 29 & 30 were checked / discussed in class – focus on Key Features of Functions & Defining the Domain & Range when given a graph.
