“My Puppy Makes a Pizza”

My puppy makes pizza.He bakes every dayIn a chef hat and apronhe's quite the gourmet.

He'll roll out some doughand he'll give it a toss,then spread on a generoustopping of sauce.

He'll heap it with cheesesand mountains of meat,but, still, it's not somethingyou'd probably eat.

For though he makes pizzawith obvious flair,it all ends up coveredwith slobber and with hair.

Famous Native American - Sequoyah

Sequoyah was a Cherokee silversmith. In 1821 he completed his independent creation of a Cherokee syllabary, making reading and writing in Cherokee possible. This was the only time in recorded history that a member of a non-literate people independently created an effective writing system.[1][4] After seeing its worth, the people of the Cherokee Nation rapidly began to use his syllabary and officially adopted it in 1825. Their literacy rate quickly surpassed that of surrounding European-American settlers.

Born c. 1770 Taskigi, Cherokee Nation (near present day Knoxville, Tennessee)[1]

Died c. 1843 Tamaulipas, Mexico

Sacred Writing TimeDid you come to class with an idea to write about?

As soon as class starts, quietly make that pencil dance!

It’s November 13. Today is “World Kindness Day.” How might you show kindness today?

Trivial Fact of the Day: Pound for pound, wood is stronger than steel.

Interesting Quote of the Day: “It takes courage to be creative. Just as soon as you have a new idea, you are a minority of one.” --E. Paul Torrance (American Psychologist and Author)

Vocabulary Word of the Day: tedious (adjective) – use this word to describe a person or event that is boring or dull. Outside of school, what is the most tedious thing that you have to do? Could you write about it so that it sounds interesting?

Adjectives• Comparative: Making a comparison between

two nouns.– Comparative Adjectives have an “er” added to the

end of the adjective.• Ex. Jack is taller than Jill.

• Superlative: Making a comparison of three or more nouns.– Superlative Adjectives have an “est” added to the

end of the adjective.• Ex. John is the tallest of all.

Page 33: Math Challenge!

• Proper Adjectives

– If it’s a proper noun, it can become a proper adjective.

What, you ask, is a proper noun? Think… think… the name of a noun is a proper noun.– Ex. I went to China. (proper noun)

I ate at a Chinese restaurant. (proper adjective)

Page 34: Math Challenge!

• Demonstrative Adjectives

• This, That, These, and Those

• I know… I know… LOOK FAMILIAR?

• If one of these words is used before a noun or a pronoun, it’s an adjective.

• Classify, people. Classify.

On a side note…• Using strong adjectives as well as abstract

nouns help to develop a good character.

Greatest Common Factor

Page 42: Math Challenge!

Do you remember the GCF?

18: 1, 2, 3, 6, 9, 1827: 1, 3, 9, 27

The GCF, or greatest common factor of 18 and 27 is 9.

Now, which one was the denominator?

The number on the bottom!

Page 48: Math Challenge!

Now we must blend our knowledge…

How can we link the term “least common multiple” with the

term “Least Common Denominator”?Hmmm…When we listed the multiples of two or

numbers that we were comparing, the least common multiple was the smallest number

found in both or all the lists!

So, I bet the LCD works like that with fractions!

Page 49: Math Challenge!

The LCD of 2/5 and 1/8 is 40.

Let’s find the LCD!Guided Practice

Multiples of the denominator: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50

Multiples of the denominator: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80

So, what is the LCD or Least Common Denominator (use LCD when referring to fractions)?

Step 4: Rename each fraction as an equivalent fraction with the

LCD as the denominator (12). Monday8 x 4 = 323 4 12

Tuesday19 x 2 = 38 6 2 12

Wednesday11 x 3 = 33 4 3 12

So, now that you have equivalent fractions with matching denominators, which day did Kayla

practice the longest?
