Ms. Petropoulos' Biography

Ms. Petropoulos grew up in the suburbs of Chicago and holds her BA in English Language and Literature from the University of Chicago. She earned her MEd in Elementary and Middle-School Education from DePaul University in Chicago. Ms. Petropoulos is endorsed to teach middle-school English Language Arts, French, Social Science, and Science.

 

This is Ms. Petropoulos' ninth year of teaching with Chicago Public Schools and her second year at Decatur. Prior to Decatur, Ms. Petropoulos taught Exploratory Science (STEM Lab) for four years to Pre-K through 8th-grade students at Saucedo Elementary in Little Village. Before that, way back in the ‘90s, she taught Library Media to Pre-K through 8th-grade students and then First Grade. After that, she worked full-time for eighteen years creating K–12 curricula for the Great Books Foundation’s Junior Great Books program, Encyclopædia Britannica, and National Geographic Learning.

 

Being an editor allowed Ms. Petropoulos to work flexibly at home so she could cook healthy, delicious meals for her family and spend time with her two sons as they grew. When her sons reached middle-school and were more independent, Ms. Petropoulos realized she missed exploring this fascinating world with children and missed providing opportunities to help children find their passion in life! So, she returned to teaching.

 

In her spare time, Ms. Petropoulos loves reading, writing poetry, gardening, birdwatching, and thrift shopping. She also enjoys playing the violin, bass guitar, and electric keyboard—while her pet birds sing along.

Week 10: 10/28 - 11/01

G4 Math
Students represented fraction units with diagrams and equations and solved problems in which a unit fraction is multiplied by a non-unit fraction or mixed number. 
 
G4 Science
Students continue to follow the design cycle to build wind turbines. The goal is to have their design spin from any which angle the wind blows at the turbine.
 
G5 Math
Students continued to measure with different units and convert measurements to different units using ratios that do not include 1.
 
G5 Science
Students continue to plan their investigation of a particular constellation throughout the year using our curriculum's online simulation.

Week 9: 10/21 - 10/25

Grade 4 Math
Students completed practice lessons and games about fractions as quotients and fraction multiplication to prepare for our Unit 2 Test on Wednesday. On Thursday, we began Unit 3: Multiplying and Dividing Fractions with a fun paper folding activity and ended the week with representing fractions of fractions and mixed numbers. (See the new Caregiver Guide for Unit 3 linked above.)
 
Grade 4 Science .
Students discussed how wind turbines work and started discussing how their design works to convert motion energy into electricity.
 
Grade 5 Math
Students completed practice lessons about ratios to prepare for out Unit 2 Test on Thursday. On Friday, we started Unit 3: Rates and Percentages. ((See the new Caregiver Guide for Unit 3 linked above.)
 
Grade 5 Science
Students read a book called "Star Scientist" to understand how scientists plan their investigations and follow a systematic approach to gathering data.

Week 8: 10/15–10/18

Grade 4 Math
We will be having our Unit 2 Test on Wednesday. To practice with your student at home, please click to download the practice packet "Grade 4, Unit 2: Fractions as Quotients and Fraction Multiplication" below.
 
Grade 4 Science
Students discussed what engineers do and why what they do is important to solving world problems that affect everyone.
 
Grade 5 Math
We will be having our Unit 2 Test on Thursday. To practice with your student at home, please click to download the practice packet "Grade 5, Unit 2: Introducing Ratios" below.
 
Grade 5 Science
After tracking several constellation examples, students discussed how constellations are not necessarily visible throughout the year. 

Week 7: 10/7–10/11

Grade 4 Math
Students continue to work with multiplying and dividing fractions through word problems, using visuals, manipulating digital visualizations, and creating their own word problems.
 
Grade 4 Science
Students discussed how a backup electrical system would work for a hospital in a city during a blackout. Students continue to consider how energy changes form and can be converted to provide optimal results in an electrical system.
 
Grade 5 Math
Students continue to explore the importance of ratios in various recipes, paint mixture scenarios, and weight comparisons.
 
Grade 5 Science
Students made constellation posters and considered how best to track the night sky throughout one year using their sky tracking simulation. They also recreated Earth's orbit in Scratch, using Scratch coding.
 

Week 6, 9/30–10/4

Grade 4, Math
We started Unit 2: Fractions as Quotients and Fraction Multiplication. Our Unit Story is about how unexpected guests at a party make it necessary to divvy up the resources. We have been exploring fractions as quotients and creating our own word problems involving it.
 
Grade 4, Science:
We considered how to lower the energy usage in a city called Ergstown. As engineers assigned to this city's energy problem, we have been experimenting with different energy inputs and outputs. Together as a class, we have hypothesized what we think is the best energy source in put and the most efficient energy output for Ergstown.
 
Grade 5, Math:
We started Unit 2: Introducing Ratios. Students have been comparing amounts of ingredients to complete a recipe and amounts of different types of fruits that measure equally. 
 
Grade 5, Science:
Students considered how gravity behaves on Earth and how the concept of "up" is relative. Whole class discussions evolved to realize that the concept of "relative" relates to more than just gravity.

Week 5: 9/23 - 9/26

Math:
This week was a short but important one! Both Grades 4 & 5 reviewed for their math unit 1 tests before taking them at the end of the week! We will be starting unit 2 for math in both grades on Monday of next week.
 
Science:
Both Grades 4 & 5 are about halfway through Unit 1! Grade 4 students are continuing to research energy forms and transformations. We had a great discussion about how the total amount of energy is always the same in the universe, and how energy is always changing forms. We considered why the potential and kinetic energy changes in a pendulum as it moves, when it has the most and least of each, and how the pendulum stops because of air resistance, which is a force of friction. We also considered how fossil fuels are made from material that was once living and that our cars may just be running on the energy from a T-Rex for a moment!
 
Grade 5 students watched and discussed several captivating satellite videos showing patterns in how Earth appears over time as it rotates throughout the day, and patterns in how the force of gravity behaves the same on any object (comparing a feather and a hammer falling at the same rates on the moon!). We also discussed how, again!, air resistance changes how the feather falls on Earth, compared to a hammer, and why air resistance, or friction, doesn't affect the falling feather's rate on the moon.

Week 4: 9/16–9/20

Grade 4
Math: Students continued to calculate the area of irregular shaped prisms by either
* dividing the irregular shape into two regular shaped prisms, finding both their volumes and adding them together
--OR--
* finding the volume of a larger, regular shaped prism and subtracting the missing piece's volume
 
We have almost completed our first UNIT!!!!
OUR GRADE 4 UNIT 1 ASSESSMENT WILL BE ON WEDNESDAY, SEPTEMBER 25! Students should make sure to check that they have completed all Past Due Desmos assignments in their Google Classroom/Desmos. Parents who would like to practice with your student at home: Please click here to download "Grade 4 Unit 1 Volume: Unit Support for Caregivers." This resource has practice problems for home.
