## Monday, September 16, 2013 - Finding GCF and LCM, Using GCF with the Distributive Property

__Homework__"

**Practice p.80-81**" was the worksheet given today and will be posted tomorrow. Students can use any method they are most comfortable with to find the GCF and LCM of the given pairs. Organized work is due Wednesday.

__Bellwork__Students found the GCF and LCM of the following pairs of numbers #1-5 by listing factors and multiples or by using the Ladder Method. Both methods were used when presenting solutions.

**Graded work returned today**:

**Grocery List Project and Sales Tax and Discount Quiz were returned.**Solutions were given and discussed in class.

For the quiz, students were instructed not to estimate when finding the product, sum, and difference. For questions where students were asked to "Label / Identify," students were asked to identify what the numbers represented in context of the question. For example, 49.99 for question 2 represents the original cost of the dragon. Students were told not to use math terminology when labeling numbers such as minuend, subtrahend, quotient, etc.

Instead of grading on a scale out of 20, students were graded on a scale out of 17. #21-25 were originally bonus questions, but I decided to count them towards the 17 needed for a 100. Students earned 1 bonus point for each question correct above 17. The highest score that could be achieved was 108.

__Classwork__3rd and 6th period began examining and using the GCF with the distributive property to rewrite expressions. The PowerPoint below was used to introduce the concept. The "BABY" handout was provided as well as 10 guided practice problems.

## Wednesday, September 18, 2013 - Dividing Fractions

1. GCF = 15 , LCM = 180
2. 8 (7+9) 2(28+36) is another expression that is equal to 56+72, but it is not in simplest form. The expression is in simplest form when it represents the multiple of the sum of two whole numbers with no common factor. 3. 3 - [2(0.7)+0.7] = how much water was left for the third beaker 3 represents the total amount of liters Karen used. 0.7 represents how many liters of water Karen poured into the 1st beaker 2(0.7) represents how many liters of water Karen poured into the 2nd beaker 2(0.7) = 1.4 L So far, Karen has poured a total of 1.4 + 0.7 L = 2.1 L into both beakers What's left for the third beaker is 3 - 2.1 = 0.9 L 4. Remember to divide by 4.1. 4.1 is the divisor. When moving the decimal point, you are multiplying the number by powers of 10. |

**Due date for homework "Practice p.80-81" was extended to Thursday to assist students on #35 and #36. Work will be graded for accuracy.**

In small groups, students worked on "Bagging Snacks" task. This task is different from the Ferris Wheel and Looking for Cicada Cycles tasks. In this situation, we must divide the given items and use factors. In Ferris Wheel and Looking for Cicada Cycles, we need to use multiples.

## Thursday, September 18, 2013 - Multiplying Fractions by Fractions

**Homework - "Practice p.80 - 81" was collected. Bell Work and Homework from the previous week was returned.**

Bagging Snacks problems A and B were completed as well as #39 - Conjunction of Planets. Attachment is located above under 9/18/13.

In preparation for dividing fractions, we reviewed renaming mixed numbers as improper fractions, improper fractions as mixed numbers, simplifying and multiplying fractions. Please review with the Powerpoints below.

## Friday, September 20, 2013 - Dividing Fractions

**Today's Bell Work involved a quiz using concepts from previous Bell Work assignments. Students could earn up to 15 points for 100%, 15.5 points for 103%, 16 points for 107%, and 16.5 points for 110%.**

Bell Work for the week was collected after the quiz. It included Bell Work from Friday, 9/13/13, through Thursday, 9/19/13.

Guided practice was given for multiplying fractions using #1-4 from p.266 of the Holt textbook. Students completed #6-24 (even problems) in group and turned this in for grading. The following presentations were used to guide students in using the division algorithm for fractions. The worksheet used involved grouping with fraction models in order to help students understand the division algorithm. Please use the lesson videos and interactive lessons for further support.
