Why use visual tools when teaching MATH?

* Makes critical information more explicit

* Helps students focus on critical features

* Provides an alternative (visual) format for remembering semantic math information

* Organizes students’ thinking

* Reveals structures that may not seem obvious to some students

Math competencies in which visual tools are particularly useful….Math concepts / terms / definitions

Math processes / calculation procedures

Math rules

Rhombus TrapezoidMonomial Binomial Trinomial Polynomial

When to apply different systems of linear inequalitiesPythagorean Theorem – when it applies

Steps to computing unknown angles Steps to computing DOTS (Differences in Two Squares)

Adjacent Angles: linked. Share a vertex and a side.Vertical Angles: formed by intersecting lines (opposite each other).Congruent Angles: angles with equal measure.

“VERTICAL ANGLES ARE CONGRUENT”

Adjacent, Vertical,

Congruent

So what? What is important to understand about this?

Learning Geometry has 2 Main Ideas: Vocabulary and Pictures.

Complementary Angles: two angles whose measures’ sum is 90 degrees. (each angle would be the “complement” of the other) “right for each other”Supplementary Angles: two angles whose measures’ sum is 180 degrees.(each angle would be the “supplement” of the other)

Complements&

Supplements

Parallel Lines: in the same plane, but never intersect.

Perpendicular Lines: lines that intersect forming 4 right angles.

Lesson 7.2 - ANGLES Is about …

Identifying and Classifying Angles

Main idea

Identifying Angles

Angle – formed by two rays or segments with a common endpoint

Vertex – the common endpoint (vertices)

Acute – between 0 and 90 degrees

Right – 90 degrees

Obtuse – between 90 and 180 degrees

Straight – 180 degrees

Main idea

Finding Complements and Supplements

Complementary Angles – two angles whose sum equals 90 degrees.

(each angle would be the “complement” of the other)

Supplementary Angles – two angles whose sum equals 180 degrees.

(each angle would be the “supplement” of the other)

Main idea

Finding Angle Measures(using angle relationships)

Adjacent Angles – linked, share a side and a vertex

Vertical Angles – (formed by intersecting lines) opposite from each other

Congruent Angles – angles with equal measures

BIG PHRASE:

“Vertical Angles are Congruent!!”

Don’t Forget About The Test Next Wednesday

will be about

Order of Operations, Distributive Property, Mean, Median, Mode, and Range

Wednesday, August 29th

Order of Operations

1) Work Grouping Symbols – ( ), [ ], fractions

2) Work out exponents

3) Multiply or Divide

4) Add or Subtract

Distributive Property

9(4+5) = 9(4) + 9(5)(8-2)5 = 5(8) – 5(2)

a(b+c) = ab + ac(b-c)a = ab - ac

The AVERAGE woman is mean….

-add up all of the numbers-divide by the number of numbers

Median

The median of a highway is the MIDDLE of the road….

-put the numbers in order-if there are two middle numbers, find their average-if there is only one, it is the median

MOST = Mode….

-the number or numbers that repeat the most times (can be more than one mode or no mode)

The difference in the largest and smallest numbers in the data….

-once in order, subtract the first number from the last

V = Bh

B is the area of the base.

Ex. 4:

Pyramids/ConesV = 1Bh

3B is the area of the base.
