## We are Mathematicians

The Unit 4 Test went home Monday. Please sign and return it to school before Friday.

We started Unit 3, Linear Measures & Area last week. So far, we practiced measuring line segments using U.S. Customary units. We learned how to use personal references to estimate the length of various classroom objects using inches, feet, and yards. We practiced measuring to the nearest whole inch, 1/2 inch, and 1/4 inch.

We also used personal references to estimate the length of classroom objects using centimeters, decimeters, and meters. We practiced measuring to the nearest centimeter, 1/2 centimeter, and millimeter.

Later this week:

• We will continue using what we know about measuring to help us determine the perimeter of various polygons.

• We will review what we know about multiplication to find the area of rectangles.

Multiplication Quiz: Friday, January 15th

Please continue to practice x4 and x8 facts every night. Since this Friday's quiz happens to fall on a Day 6 (with the other spelling, reading, & vocab tests), your child can choose to take the x4 or x8 facts quiz on Thursday if he or she would prefer.

We are reading a biography about Thomas Edison this week by author and illustrator Michael Dooling.

This week's skill focuses on main idea & details. Good readers think about the main idea, or the important idea about a topic, as they read. Readers can use a graphic organizer to record details that support important ideas they read about in a text. This skill will help students summarize key concepts.

We learned you can find a main idea of a particular paragraph, chapter, or book. Sometimes the main idea can be found in the beginning of a paragraph, chapter or heading, or book title.

You will find the Journeys parent connection letter attached to the email.

The reading/vocabulary test will be Friday, January 15th.

## Spelling

New spelling lists were sent home Monday. The spelling test will be Friday, January 15th.

## We are Writers

Over break the 3rd grade team spent time reflecting on the students' writing. We have decided to start Informational Writing after the Persuasive Writing Unit.

Throughout the first section of the Persuasive Writing Unit, your child will gather and support "brave and bold" opinions.

How do writers find ideas for persuasive essays, speeches, and letters?

We learned one strategy! They look at the world around them (their classroom, school, town), think about a problem that exist, and imagine a solution. This kind of reflection will help stir up feelings and emotions that are important to your child.

Here are some opinions the students shared over the past several days:

• Third graders in Mrs. Daniels class would love a class pet.
• Our classroom library should be kept neat and organized.
• You shouldn't litter.
• We should have a Friday cleanup to organize our desks.
• 3D students need more Geronimo Stilton books in our classroom library.
• Students in 3D can help fix books in the Book Hospital bin.
• Go Noodle breaks help third graders feel good throughout the day.

This week, we will continue to gather and write about many different ideas, hoping to fill up our notebooks with opinions that matter.

## We are Chemists!

The Mad Science Assembly was a great start to our new unit... Chemistry!

After the assembly, we kicked off the unit by sharing all the things that came to mind when we thought about the word chemistry.

• chemical reactions
• potions
• dry ice and soap will cause a chemical reaction
• vinegar and baking soda will cause a chemical reaction
• flash paper will disappear in a fire
• gasoline is a flammable chemical
• there are three states of matter: solids, liquids, and gases
• be safe

We also shared our wonders:

• What are chemicals made of?
• What is the formula of some chemicals?
• Are all chemicals bad for you?
• Can they make you sick?
• Why do chemicals react?
• What are the first 10 elements on the periodic table?

We will be working with household chemicals (like baking soda, for example), which means we'll have to be safe. We came up with a list of rules to follow while we work in our laboratory. Here's what we think is important for scientists to remember:
