Happy Holidays!

Students finished up their Hershey Chocolate Kisses Lab and letter.

Happy Holidays to you and your family.

Chocolate Kisses - Day 2

Some students were working on their Test 4 Retakes and others continued the work with their chocolate Kisses Lab. (Modifications/adjustments will be made for individual students who needed the time for retakes.)

LINK: How to use a protractor for Circle Graph


After students are finished with calculations and constructing their own circle graph, students need to write a letter explaining their results. A copy of the checklist requirements is attached. Graphs and letters are due by the end of class time on Tuesday.

Chocolate Kisses Math Lab

After all students were given the chance to finish Test 4, I introduced the Chocolate Kisses Math Lab. I have posted the "letter" from Hershey that requests our team to conduct a bit of data collection. It is a bit "hokey", but fun for this time of year. It allows students to use data collection to find percentages and use the percents to hand construct a circle graph. Why, you may ask, am I required students to hand make a graph when we can use technology to create the graph? I want students to understand that the "fraction" (percent converted to decimal) is used to determine the degree representation on the circle.

Test 4 & Update

After all students were given the chance to finish Test 4, students worked on IXL, Level I, J.6 (ratio and proportions). However, some students were required to use their time with completing some missing assignments.

Test 4

Test 4 was given to students today. MTN's were collected after completion of the test. MTN's will be returned to students on Wednesday and all tests will be returned to students on Thursday.  That is to allow students who wish more time to complete and proof their test the time they deserve. At that time we will review the test with students and help prepare the students who will be taking the retake on Monday, 12/22. Tomorrow will include an introduction to a Math Lab, "Hershey Kisses," to apply their knowledge of percents and how to use percents in constructing a circle graph.

PLEASE NOTE:

Only students who have finished the U.S. History of Populations assignment will take part in the Math Lab. At this writing, only 54.3% of the students have turned in the assignment. Please get your assignment in to me first thing tomorrow morning.

Test 4 Review

REMINDER: Test 4 will take place on Tuesday, 12/16/14!!!!!

Students will again be allowed to use MTN to complete the test. Student's may not use the paper titled, "Practice Items prior to Test 4". Students may however, use the paper to fill in missing parts of their notes or extend their notes into their MTN. This is a good way to help review and study for a test. This is a copy of the review conducted in class today in order to prepare for tomorrow's test:

PRACTICE ITEMS prior to Test 4

Review:

7 x  -8 = _____                                     -2 x -2 = _____                                     -1 + 4 = _____                                     -6 – (-1) = _____

Give me a number that is between 0 and 1 (percent, decimal, or fraction): ________________

Working with Percents:

A dress that retails for $160 is on sale for 60% off. What is the sale price of the dress?

A dress that retails for $80 is on sale for 30% off. What is your savings?

An executive, whose salary is $400,000 per year receives an increase of $25,000 per year. What is the percent of increase?

The temperature is 32⁰F at 6:00am. The temperature drops to 2⁰F by 6:00 pm.  What is the percent of decrease?

During her first six months, Susie gained 25% more than her birth weight. If she gained 2 ½ pounds during this period, how much did she weigh at birth?

Mrs. Kenny and her husband go to a nice restaurant and spend $145 on food. What is the total bill with an 18% tip?

 MTN's will be collected after the test is complete. Here is a photo of a student's TOC. The focus is from 11/24/14 to 12/10/14. 

FOCUS: 11/24/14 to 12/10/14

History of US Population - Day 2

REMINDER: Test 4 will take place on Tuesday, 12/16/14!!!!!

After reviewing the chart in MTN, "History of US Population," partner groups began answering the six questions. A copy of the worksheet is below.

DO NOT DO #6. Answer the REVISED #6 that is below.

6.  Using the most recent federal census data (Link from blog), fill in the table below for populations of Massachusetts, New York, and Pennsylvania. Then predict the populations for the three states for 2020.

States/Census	2000	2010	2013, estimate	2020, prediction
Massachusetts
New York
Pennsylvania

Students will also need to use the two links below for questions 5 and 6:

QUESTION #5                                                                           QUESTION #6

This worksheet with graphs is due tomorrow morning -- Friday, 12/12/14

History of U.S. Population - Day 1

In order to practice reading graphs and apply students' new skill of working with percent changes, students will be working in partner groups to answer questions (question sheet will be given tomorrow). Using the graphs and given the total US population numbers from 1800 to 1950, needed to solve the the populations for NY, MA, and PA for 1800 to 1950 (make sure these numbers are in your MTN before tomorrow's class:

                                             Population of the U.S. (nearest million)

                               1800                       1850                           1900                              1950

US:                          4,000,000            23,000,000               76,000,000                     170,000,000

New York:                  400,000              2,300,000               12,160,000                       15,300,000

Massachusetts:          400,000                 690,000                 3,800,000                         3,400,000
Pennsylvania:             440,000               2,070,000                 7,600,000                        10,200,000

MAKE SURE TO BRING THIS TO CLASS TOMORROW!

Guided Practice: Percent Increase/Decrease

Due to the weather and the early release, all classes were a bit shorter. This worksheet (located in MTN) is what students and their partners worked on in class -- practicing with percent increases and decreases.

GUIDED PRACTICE

1. There are 16 students registered in math class a week before the semester begins. One week later there are 20 students registered for the class. What is the percent of increase?

2. On the first day of the semester, 20 students are attending in a class. At the end of the semester, there are only 16 students in the class.  What is the percent of decrease?

3. A man working for Company A is earning $8 per hour. If he gets a raise of a dollar per hour, find the percent of increase.

4. A man working for Company B is earning $12 per hour. If he gets a raise of a dollar per hour, find the percent of increase.

Working with Percent Increase/Decrease

First, a homework check was conduct (assignment from Thursday) and then reviewed the showing of work on the last five examples from "Match It and Prove It". SADLY, Only 8 out of 51 students have both parts of the assignment finished. We had a huge team meeting about this poor response since the lack of completed and returned homework is a systemic problem in every class. In math, both assignments will be checked again tomorrow.

I announced that Test 4 will take place on Tuesday, December 16 and the Retake will be on Thursday, December 18.  My hope is to also conduct at least one (hopefully two) math labs between now and before our departure for the Holiday Break.

Our time for the week will be spent on "Working with Percent Increases and Decreases".  Written and pictorial notes are in student MTN's. This is a picture of the skeleton which we began in class today.

"N" refers to the "New number; "O" refers to the "Original number.

Do you have these notes? PERCENTS

THESE NOTES MUST BE IN YOUR MTN.

Review Notes for working out a percent of a number and the percentage between two numbers.

In class we reviewed the answers to the game record sheet (and homework). Make sure you have these answers along with showing your work on the attached sheets.  Finish the last five examples (K - O). You must show your work (labeled) and have the correct answer on the record sheet. IF your answer is different then mine, go back and check your work!
