Why do we need common denominators? (Hope to end confusion about WHEN we need them)

Visual-shade in half of a third, 1/4 of a fifth, etc. What do you notice?

Government spending

Producing a movie, how would you divide up budget (among actors, ads, props, etc). Use at least three different demonimators l. What must your fractions add up to?

Order of ops

Bedmas/bodmas/pemdas/christmas?

Take a number, double it and add 6. Take the same number, add 6 then double it. Does order matter? What is the only case these would be equal

Square one video of battling positives and negatives (... blue and red monsters to illustrate that they cancel each other out and whatever is left is your answer

Number Systems

IrinaAmlin — 2016-01-15 04:31:35 UTC

Idea of using images to help remember - Natural (sesame street, the count or someone counting, thermometer for integers, etc)

Number Systems - International numbers

IrinaAmlin — 2016-01-15 04:34:36 UTC

Do we want to include this type of thing at all? Too long a topic but posting in case we want at least an image if nothing more.

Fraction Activities

Patterns in multiplying by 1/10, 1/100, etc

Decimals Activities

IrinaAmlin — 2016-01-15 04:37:41 UTC

Powers of ten investigation, can be combined with fractions base 10,100 etc.

Exponents - conventions

IrinaAmlin — 2016-01-19 02:48:14 UTC

An exponent applies to its immediate base. ex: 2+5^3 vs (2+5)^3.

Exponents/Order of ops - equivalence

IrinaAmlin — 2016-01-19 02:51:23 UTC

3^6 + 2^6 same as (3+2)^6?

Fractions

IrinaAmlin — 2016-02-02 06:01:03 UTC

COMMON DENOMINATORS - In order to accurately compare fractions, we need a common denominator. Until this is achieved, it is like comparing Euros and Dollars. Which is more? 50 euros or 42 dollars? We need a common currency in order to understand how these numbers relate to one another. Similarly, we need fractions to have the same denominators to accurately compare them, order them, and even add or subtract them.

Adding/subtracting fractions

Multiplying/dividing fractions

“OF” and multiplication: When you take a “fraction of” something, you are taking a small peice of it. You may have heard the saying “at a fraction of the cost”. This means you are multiplying the cost by a fraction.

The nice thing about multiplying fractions is there is no catch. Simply multiply the numerators by the denominators!

ACTIVITY - insert brackets to make this equation true. (ie: both sides EQUAL)
