Snapshot: 6 Order of Operations
Sixth grade grappled with why it is necessary to have a single answer when solving an expression. We discussed how mathematics is a form of communication and that if every "sentence" had different meanings, it would be very hard to communicate clearly and effectively. Hence, the importance of the order of operations. This foundation is helping us develop the "grammar rules" of how to create sentences and share our mathematical thoughts.

Snapshot: 8A Slope Battleship
To solidify and extend our understanding of slopes of lines and to get practice graphing linear equations, we played Slope Battleship. Teams of two battled with each other to sink the other team's submarine, destroyer, and battleship. Each team gave the other team an equation for a line and they would report back if it was a hit or miss. Some games got very animated!

Snapshot: 7A Variables & Expressions
The seventh graders are grappling with making the leap from concrete numbers to abstract algebraic symbols. This transition is developmental and is nurtured by regular exposure to patterns and looking for connections to the concrete examples. This week, 7A was working out the concept of like algebraic terms. How is x different than an x squared? What does 2x mean? How do we do operations on like and unlike terms? These the foundation the algebra that is to come.

Snapshot: 6 Millet by the Million
The sixth grade took time to explore the meaning of place value and the relative size of large numbers. They worked as a collective to count out a million millet seeds to visual the number one million. We started by individually counting out 10 millet. Each student then counted out 100 millet. Many were surprised by how small one hundred appeared in their Dixie cups.

100 millet |
It was fun to do a collaborative project with the whole grade. Now, when we talk about millions, we have a point of reference to understand and conceptualize this very large number!

8A: The Banach-Tarski Parody
My classes quickly learn that I am easily side-tracked by interesting math ideas and conversations. This VSauce video was sent to me by a student and I felt compelled to share it with the rest of the class. In the last two years, we have tackled the concept of infinite, on multiple occasions. This video does a tremendous job of simplifying this abstract and complex idea. Our brains were stretched and I loved the interesting ideas it generated in class. I hope if you are interested in learning more, you will check out the links on the YouTube page and the many books referenced at the end of the video.

Curriculum Night 2015
It was great to meet and see so many parents at Curriculum Night! It is a pleasure working with your daughter/son and I look forward to an exciting and productive year. In case you missed the evening, you can find electronic copies of my handouts below. I have included a couple of helpful articles and a list of questions that might help you guide working with your child in math.

Advice for Parents: Helping Children with Maths by Dr. Jo Boaler
Do your children tell you how exciting maths is or how objects that
you count stay the same number even when you move them around? How
patterns can be seen in flowers and pine cones? If they haven’t started
school yet they might talk about maths with curiosity and wonder, but if
they have begun they are more likely to tell you that maths is
confusing and scary.Dr. Jo Boaler, professor of mathematics and author, examines the way that maths has become the most dreaded subject for many school children, plus how we can help them begin to enjoy and even excel at it.
This is a document put together by the South Brunswick School District in New Jersey that offers a list of questions to engage your child to think critically about what they are doing in math. Also included are a list of resources for math.

Snapshot: 7A Number Visuals
The seventh grade started off the year making connections between numbers and visualization of numbers. We studied the image below to find patterns and relationships between numbers. We found patterns of factors, multiples, and prime numbers. We predicted and designed visuals for 36 and 40. What do you notice when you look at these numbers visualized?

Snapshot: 8A Collaborative Problem-Solving
It was great to welcome the 8's back from their travels to Catalina Island. We kicked off the year with a collaborative problem-solving activity called "31-underful!" Each table was given a deck of cards and required to make a 5x5 array where each column and row had a sum of 31. Each table and group had a different approach and different way to solve the challenges that emerged along the way. Each group presented their strategy and solution to the whole class. It helped to dust off our math skills and start of the year communicating their thinking.

Math is.....
"Math is......" was the prompt. The sixth graders responded to this prompt and the answers were diverse. This is a sampling of the answers turned in. We are getting to know each other and I love seeing their voices emerging already!
