This week we are starting the last topic of Module 1 - Ratios of Scale Drawings. We will be relating the constant of proportionality / unit rate to a term called scale factor. When you multiply the lengths of the sides of any object by the scale factor, you can reduce or enlarge an object while keeping it proportional to its original size. Multiplying by a number greater than one enlarges an object and multiplying by a number less than one reduces, or shrinks an object. We will most likely be looking at a test mid next week.
The Quizizz code for this week is 116694. It will be a review of volume and surface area of 3-D objects.
This week is also Spirit Week! Students will get a chance to participate in some fun dress-up for free! As always, all outfits must be school appropriate.
Monday: Mismatch Day
Tuesday: PCA Pride Day (PCA Pride top with uniform bottoms)
Wednesday: Crazy Hair/Hat Day (students must be in uniform)
Thursday: Pajama Day
Friday: NO SCHOOL (Teacher PD Day)
**UPDATE** Here is a link for the video we watched in class this week. It explains 3 different methods for solving proportions.
Welcome to our first full week of 2019! Math League has their 3rd meet of the school year on Monday at Smyrna Middle. On Tuesday, 7th and 8th grades will be going on a field trip to the Dover Skating Center. In math class, we will be covering Lessons 12-15 and we will most likely have a quiz later in the week. Students learned more about unit rates last week and how this represents the amount per one. We studied various real-world scenarios involving unit rates including miles per gallon, cost per pound and cups of flour per dozen cupcakes, just to name a few. Understanding proportions, dividing fractions and being able to interpret graphs will continue to be important concepts. Late this week we will most likely get into discussions of scale drawings and potentially scale factor.
I have started after school help hours again on Tuesdays and Thursdays until 4:30. This schedule will continue until the next cycle of tutoring begins.
This week's Quizizz topic is Proportions & Unit Rates. The quiz is due by Thursday night and the code is 263374.
Here is the New Year's Review Booklet Answer Key from last week if students would like to check their answers.
Don't forget, next week is a 4 day week for students as Friday, Jan 18 is a PD Day for teachers. It will also be Spirit Week! Stay tuned for additional details!
Have a great week!
Happy New Year and Welcome Back!
This is going to be a very short week (just Thursday and Friday)! We will spend much of Thursday reviewing and ensuring we remember the key concepts from 2018 as we prepare to tackle to remainder of Module 1. Students will need to be comfortable solving proportions (i.e. 3/x = 5/8) and we will also be practicing more conversions (cm to m or inches to ft, for example). It is important for students to use their units when they convert quantities so that they can ensure they have the conversions set up properly. This method of using the units in the conversion is called dimensional analysis. Here are some video examples of this concept:
Dimensional analysis using the distance = rate * time formula
Converting from yards/min to feet/min
We will use these skills of solving proportions and dimensional analysis (as well as what we already know about unit rate) to understand a concept called scale factor. A good real-world example for this is reductions and enlargements. If you want your reduction or enlargement to look proportional (meaning none of the dimensions are distorted), you need to use a constant scale factor. This is similar to what we discussed in the beginning of Module 1 when we talked about the constant of proportionality, k, or unit rate.
Don't forget, field trip forms for the STEM skating trip are due Friday, January 4th! Trip is Tuesday, January 8th!
HERE is the extra credit packet for winter break. It is due the day students return (Thurs. Jan 3rd).
Don't forget, field trip forms for the STEM roller skating trip are due January 4th! Cost is $16. Trip will be on Tuesday, January 8th.
**UPDATE** Here is the crossword answer key and here is the Proportional Relationship vs Non Proportional Relationship answer key (pink sheet)
**UPDATE** Here is the Mid Mod 1 Study Guide Answer Key**
Well, we are almost to our Christmas Break! This week is sure to go by fast as we have some exciting activities going on around school. On Thursday, there is an in-school concert for band/choir/percussion on at 8:30. On Friday, we have our Honor Roll Assembly from 10:50 - 11:50. All those who made Honor Roll (A's and B's) and High Honor Roll (A's) will be called to come up on the stage in the auditorium to be recognized in front of their peers, teachers and any parents that attend. Our last day this week will end with an upper school gathering at 2:00 on Friday.
In math class, students have been learning about proportional relationships in graphs and tables and interpreting what the x and y points represent in the context of a particular problem. They have also been writing equations using y = kx where k is the constant of proportionality. Here are the posters that students finished up at the beginning of last week.
Students will be taking the Mid Module 1 Test on Tuesday or Wednesday of this week (depending on how the review of the study guide goes on Monday). Here is the study guide if a student needs a copy.
We will also have a notebook quiz this week. Students should ensure that their notebooks are up-to-date (this will also help them prepare for their Mid Module test).
This week's Quizizz code is 572829. The topic is proportional relationships. As usual, this will be due Thursday evening by 11:45 p.m.
Have a great week and a wonderful holiday with friends and family! See you in the New Year!
We are getting closer and closer to the holidays - it's hard to believe it is already that time of year! Last week we enjoyed watching The Nutcracker ballet show. Students did an amazing job!
During class this week, we will be finishing up the material for Mid Module 1 (Lessons 6 - 10) and most likely looking at a test early next week. Last Friday students created posters in class depicting various proportional or non-proportional relationships. They were able to determine proportionality using tables (looking for a constant value of k) and graphs (looking for straight lines through the origin). This week we will continue using our knowledge of equations to understand how proportional relationships can be represented using real-world scenarios. We will use what we know about dependent and independent variables to ensure our equations are set up properly and we will also be making some connections with the constant of proportionality and unit rate.
There is also a new Quizizz this week that will be due on Thursday night. The code is 329156. This is a refresher on solving inequalities, a skill that many students need additional practice with.
Here are some links for additional practice with inequalities as well as our current topic of ratios and proportions.

This Friday (12/14) is PCA Pride Day! Also, Confirmation of Enrollment forms are due this Friday!
Have a great week!
Hello! This week report cards will be going home with students in their Thursday folders. Also, Friday is a N.U.T. Day / dress to impress ($2).
In class this week we will be starting Module 1 - Ratios and Proportional Relationships. We begin with a discussion of rates (including unit rate which means per one) and learning what the word proportional means.
Example: Find the unit rate if a car traveled 420 miles in 7 hours
420 divided by 7 is 60 miles per one hour
We then explore how these types of proportional relationships are represented in tables and graphs using the formula y = kx where k represents the constant of proportionality.
There is a new Quizizz code for this week! The code is 491473. It is a review of volume and surface area.
**UPDATE** Here is the End of Mod 3 Study Guide Answer Key. Please note, in order to correctly answer 4b, you would have to know how many square meters a gallon of paint covers. Assume 1 gal = 30 sq meters for this calculation. This is not shown on the answer key.
Welcome Back! This week students will be finishing up Module 3 as we complete lessons on surface area and volume. Students will be taking the End of Module test later this week (most likely Friday). Here is a study guide that students will also be given in class to help them prepare for this assessment. Also, there is an extra credit packet available to students to complete on area and circumference of circles that will be due on Thursday. This packet is optional, but will also serve as a good review for the test later this week.
Due to the test this week and extra credit packet, there will be no Quizizz for this week. We will pick up again next week on Monday. Just a reminder, when Quizizzes are assigned for homework, students can attempt them as many times as they would like to try to get a 100%. Earning a 100% does allow students to get their name on the leader boards in the hallway and a chance to win seating of their choice for the following week.
The first trimester ends on 11/30 and report cards will be issued in Thursday folders next week.
Also, don't forget this Friday is pajama day for the Upper School!
We have only 2 days this week and then we are off for Thanksgiving Break! Last Friday we had a great time on our field trip to D.C. What a memorable experience that many will not soon forget! Thanks to all the wonderful chaperones that helped make the trip possible! We appreciate your support!
During this short week we will be finishing our discussion of surface area (lesson 21) and begin our discussion of volume. Volume should be a review topic for all students, however some of the shapes and word problems that we will encounter in these lessons will challenge students to use what they have already learned and apply it to new scenarios. When we come back from break we will be wrapping up Module 3 and getting ready to take our End of Module 3 test (most likely around Fri 11/30).
Here are some great resources if students would like some extra practice with area of 2-D shapes, surface area or volume.
2-D shapes examples
Explanation of area with examples
Surface Area video
Even though this will be a short week, we will still have a Quizizz game for hw. The code is 543620. This will be due by 11:45 p.m. on Sunday 11/25.
**Reminder - the first trimester ends on Friday, 11/30 and grades are due by Monday, 12/3. Report cards will go home in Thursday folders on 12/6.**
Enjoy the week with family and loved ones!
This week we will be finishing up our discussion of area of 2-D objects and talking about composite shapes which combine two or more basic shapes together (i.e: a semicircle with a rectangle, or a triangle with a trapezoid). We will then be moving on to discuss surface area and volume of 3-D objects. We will be having a notebook quiz most likely on Thursday of this week or early next week before break.
This week's new Quizizz code can be found at the right and will be homework for students this week. Each student needs to ensure they are using their name when they start the quiz so that they earn credit for their quiz. Quizzes are due Thursday night by 11:45 p.m. Many students have done a great job these last few weeks giving the practice quizzes a try and we even have several 100%s that we have celebrated on a leader board outside the classroom. Students who earn 100% will have their names entered in a weekly raffle drawing for a classroom privilege.
I will be offering extra help after school on Wednesday until 4:15. I will be available from 4:30 - 6:00 that evening as well for any parents who would like to meet. Please contact me if you would like to meet during this time.
Don't forget - the 7th grade field trip to the Holocaust Museum in D.C. will be this Friday.
Have a great week!
**UPDATE** I will be tutoring on both Tuesdays and Thursdays during this first session of PCA sponsored tutoring. Session 1 lasts until 12/13. During this time I will be offering extra help after school until 4:15 on Wednesdays only. Please note day and time change. This Wednesday, 11/7, I will be unavailable due to a math league competition after school.
This week students in all classes will be learning about geometry of circles including radius and diameter and using this to find circumference and area. We will have many hands-on activities that will help students discover this information and understand how they can apply it to real-world situations.
Here are some great resources for students to gain extra practice:
Diameter, radius and circumference
Circumference and area video
Tutoring begins this week! Please stay tuned for updates regarding after school days as they will change based on what day(s) I am scheduled to tutor.
Our next Open House will be Thurs. 11/8 from 3:30 - 5:30. Please click here to sign up for a time slot.
Each week I will be giving students a new Quizizz code for them to go online and complete. The code will be given on my website and will be available on the board in class. The quiz ends each week on Thurs at 11:45 p.m. Students will be recognized on a leader board outside the classroom and leaders will be given Power Paws as recognition. A winner will also be chosen from the leader board for a special class privilege. Students can attempt each quiz as many times as they would like in order to try to get to 100%. Good luck students!
