The students were focused on learning to code this week with Hour of Code. This is a website dedicated to helping students understand different languages that are needed to program computers successfully. There was a variety of challenges for students to work through. They can continue this exploration at home as the website has a large amount of resources.
When we return, students will be refining their subtraction strategies as well as revisiting their mental math skills.
I hope everyone has an excellent Winter Break. See you all in 2018.
Want to learn a new language? How about computer coding being that language?
Students spent the week practicing their subtraction strategies to help them understand how and why we regroup during subtraction. They used base tens as a visual to help them understand how to regroup and then added in the mathematical equation to match. For example:
Students also worked on a variety of problems relating to subtraction this week. The problems were multi-stepped and required students to decode the question find clues and create a process for solving. Some of the questions are shared below. What process would you do to find them?
Ms. Chapman bought 1500 pieces of candy to give out on halloween.
In September Mr. Baker bought 5624 pencils for all of the grade 4s to use this year.
If Ms. Mills had 7650 dollars to go on vacation to Hawaii and she had to spend 4438 dollars on her flight, 1527 dollars on her hotel and756 dollars on a rental car, how much money would she have left to buy souvenirs?
Ms. Bennet bought 1765 new books for the school library, she bought:
Students have finished their brainstorm and designing phase for their flashlight creation. Now students are learning the hard lesson that light can escape through the smallest of holes, even if you think an object is opaque it could be translucent and group collaboration is a difficult process. Next week the students will be presenting their products in a final write up and sales pitch.

This week students started to subtract in math. Their subtraction started with large group visuals to understand how the numbers would become smaller and why this is occurring. They then moved into strategies for subtraction up to 4 digits. Currently, students have not begun exploring questions with regrouping, as we want to ensure the students are comfortable with the process of subtraction before we look into what regrouping looks like.
For example students have been working on:
Getting as much practice with this process will be important for students. The Prodigy website is a good place to get subtraction practice in. Students can also explore this website, which has a ton of online subtraction games:

Next week students will be building into regrouping in subtraction and also working with subtraction word problems.
Students have started a new group project in our Light and Shadow unit. Students are leading a team to design an adjustable flashlight that can both increase the beam width and decrease the beam width at 1 m. This project has multiple stages and will take them to the Winter break. I have attached the section of the Powerpoint they have done so far. Talk to your child about their design and plans for being successful. If your child is becoming frustrated, remind them that all great scientists have to redesign and retest their work.
