## Mr. Rodney

### Target 1

###### Lesson Type:

New

Number Operation

:

Integer Composition

Understand that a number can be decomposed into its factors.

###### Supporting targets:

###### 1:

Define Least Common Multiple (LCM).

###### 2:

List the LCM for two whole numbers.

###### 3:

Understand that different numbers can share factors.

###### 4:

###### 5:

###### Grade:

6th

###### Vocabulary:

Least Common Multiple (LCM), Factor, Product

Activities:

Discussed the words in "Least Common Multiple" to derive a working defintion.

-Given two numbers, listed out the multiples to determine the LCM.

-Discovered that sometimes, one can multiply the numbers to find a common multiple, but it may not necessarily be the LEAST common.

-Reviewed prime and composite numbers to see how prime factorization (as demonstrated by Mr. Rodney) can be used to find the LCM.

### Home Exploration

###### Challenge Problem:

Find the Least Common Multiple of the given number sets. If you'd rather choose your own numbers and make up your own problems, feel free to do so!

###### Challenge Data:

1) 7, 10

2) 4, 12

3) 5, 8

4) 3, 5, and 9,

5) 4, 7, and 12

###### Guiding Questions:

-What is "Least Common Multiple"?

-How do we find the LCM for two numbers? Let's list out the multiples.

-When writing the multiples, makes sure that each multiple is correct before moving on. One mistake could cause a chain reaction.

###### Challenge Answer:

1) 70

2) 24

3) 40

4) 45

5) 84

### Target 2

###### Lesson Type:

###### New

###### Number Operation

###### Fractional Numbers

###### Identity, compare, and manipulate different types of fractions.

:

###### Supporting targets:

###### 1:

Understand that fractions with different numerators and denominators can represent the same size.

###### 2:

Create equivalent fractions with common denominators.

###### 3:

Understand that fractions represent quantities that have a portion that is less than a whole.

###### 4:

###### 5:

###### Grade:

6th

###### Vocabulary:

Fractions, Numerator, Denominator, Least Common Multiple (LCM), Lowest Common Denominator (LCD), Improper Fraction

Activities:

Reviewed and discussed learned understandings of fractions and related vocabulary.

-Practiced adding fractions with same denominators, some of which resulting in improper fractions.

-Used blocks to visually represent the addition of fractions and how improper fractions relate to mixed numbers.

-Piggy backing on the lesson on Least Common Multiple, students were introduced to adding unlike fractions and using Least Common Multiple (or Least Common Denominator) to convert the problem into equivalent fractions.
