TEST tomorrow

Tomorrow in class we will be finishing our end of module assessment.  

Please continue to study the practice test which we went over in class Monday and Tuesday.

Friday's Homework

This Friday we are having a slightly nontraditional homework assignment. Tonight we should be doing Exit Ticket #22 for homework.  There is an ERROR that you need to fix.  The number 175 is in the incorrect spot in the table.  

Lesson #20 Homework

Tonight's homework is a chance to show off your creativity. On the provided graph paper construct your "dream" classroom.  Use the guidelines we talked about in class and remember that we are creating a "birds-eye" view.

Problem Set #19

***Adjusted Assignment***

Problem Set #19 odds only

 Hints:

1. Find the area of the shaded region.  Then make a ratio with the actual area. 

3. The dimensions of Store 1 is 1.5 by 1.75 (use fractions instead of decimals I would but my blog doesn't like fractions.  Store 2 is 1.25 by 1.75.

5. Use the scale factor to find the area.  You do not have to make any measurements on this problem. Ignore the shaded region.

Problem Set #18 help

#1) Use the scale 1/2 to 1/3 to change 2 inches into the new package size. Perhaps a table would help. 1 inch would be 2/3 of an inch.

#2) The image of the arch in St. Louis measures 1 inch.  If 1/2 inch is 7 feet how long would 1 inch be??

#3) The scale drawing is 2 inches long. So multiply by the scale factor.

#4) Multiply the length by the scale factor (the answer is a really big number because its a skyscraper)

#5) Multiply your height in the picture by the scale factor.

#6) This time multiply by 1/4 to find the length and the width of the stamp (it's a pretty big stamp)

#7) Multiply the length and width of the room by 1/2 since 1 inch corresponds to 2 feet.

#8) The bedroom is 1/2 inch wide and 1 and 1/4 inches long. What are the real life dimensions. Is your answer reasonable?

8th Period Math Analysis

The 8th period Math Analysis is participating in the stock market game.  This involves a simulation where students are tasked with the job of managing a $100,000 portfolio.  It is very interesting to see and hear the different investing strategies students are using to build their investment portfolio.

Homework Help #17

Tonight's HW help brought to you with help from Wyatt and the rest of 9th period Home-base.

#1. One of the issues with this question is the use of cm and km in the same problem.  You need to make a ratio comparing the distance on the map to the actual distance (4cm : 56 km) then reduce.  In the end you should change the units so they match
 (1 km = 10000 cm)

#2.  Use only one of the measurements (length or width).  Again the units do not match but we know that 3 ft is 36 inches.  So the scale factor is found by making a ration comparing the scale drawing size to the actual.  (hint the answer online is incorrect)

#3.  The length of the actual battery is 1.5 inches and the scale drawing is 2.5 inches. Make a ration using these numbers.  You should know which one is the numerator

#4. The trick is they give you one diameter and one radius.  The diameter of the actual volleyball is 24 cm.  The diameter of the scale drawing is 12 cm. Make a ratio using these numbers.

#5a. Sketch (without a ruler) an envelope that is 3 times as big as the orginal.  Use the techniques we used in class

#5b, this is a reduction it should shrink in size to make it easier use 3/4 as the scale factor. The picture is a tag. That is 4 inches wide making the scale drawing 3 inches wide.

#6 Draw a triangle (right) using the scale factor (which means to mulitply) so 6 inches times 1/4 is 1.5 inches.

QUIZ FRIDAY

There will be a quiz tomorrow on Module 1 material:

Topics could be:

Unit Rate
COP
Proportional
Equations


Problem Set #16 will also be collected

Problem Set #15

There is an error on the graph for tonight's problem set.  In question 3 the graph is mislabeled.  The km and miles should be switched.  There are 8 km in 5 miles. (thank you Mrs. Clark)

5 week grades

Families and students should have received their 5 week progress reports in the mail by now.  You will notice that the grade for Math 7 is missing.  Please accept my apologies for this missing information.  Due to a family medical emergency I missed several days of school and was unable to enter the grades into the system.  This week I will send home detailed grade reports with every student.  If you have any questions please do not hesitate to contact me jhoward@addisoncsd.org

Short Week this week

October is here!!!
Note to self....start blogging more

The homework for last night was Problem Set #13 question 1-3 only

Don't forget about things like the C.O.P. and Unit Rates they were certainly applicable to tonight's assignment

Please make sure you are turning in your homework when it is assigned and including your name!!!
