Math and the movies

Image
You are probably pretty familiar with the movies put out by Pixar Animation Studios.Their most popular creations are the Toy Story films, the Cars films, Finding Nemo, and Inside Out.
Pixar has teamed up with Khan Academy to explain how math (as well as science and the arts) is important in creating their films.Take a look at this introduction video!I’m sure you will like it (even if you are not interested in the math part).https://www.khanacademy.org/partner-content/pixar/start/introduction/v/pipeline-video.
I have not watched the whole series.However, I liked the ones I have watched, I have read good reviews about the program, and I have confidence in the kind of work that the Khan Academy does.
A direct link to the Khan Academy for the series is at https://www.khanacademy.org/partner-content/pixar.If you want to go through the Pixar site, the link is at https://www.pixar.com/pixar-in-a-box#pixar-in-a-box-1-1.The Pixar site also lets you know more about the company--including informa…

Grade Six: Math 2: Study Guide

Sixth graders in Math 2 will have a test on pre-algebra concepts on Wednesday, May 23.The test will be assessed through Criterion A, Knowing and Understanding.
Key concepts to understand are: VocabularyRecognizing termsSimplifying expressionsIdentifying patterns and expressing them algebraicallyEvaluating expressions

Sixth graders, here is where you can find study information…
Your notebook If you have been taking notes during our work and discussions, this should be your best source of information.
Websites Like terms.This site has an explanation with some practice problems at the end. https://www.mathsisfun.com/algebra/like-terms.html

Grade Seven: Probability Test Study Guide

Image
Seventh graders, you know that you have a test on Thursday, May 10 (7I) and Monday, May 14 (7T).  It will be assessed as Criterion A--Knowing and understanding.  Here is a study guide to help you prepare.
Things you should know how to do: Estimate the likelihood of an event, using the 0-1 scaleFind mathematical probabilities for a variety of situationsMake predictions based on given probabilitiesCreate a tree diagram to show all possible outcomesDecide if a situation is fair or notBe able to explain your thinking in words and/or a table
Things that can help you review:
Your notebook: This should be your best source for studying (if you took notes and kept it organized).  It has vocabulary and important ideas.  You have examples of how to organize data in tables for finding mathematical and experimental probabilities.
YouTube videos: Here is a review of what probability is.  It explains how to find the mathematical probability of a specific event. https://www.youtube.com/watch?v=GMiAbQ5yUDA

Grade Six: Math 1: Fractions and decimals

Image
The sixth grade Math 1 class has begun a new unit on fraction and decimal numbers.  Some ideas will be new and others will be reviewed or clarified.  Key ideas include: Naming fractions correctlyComparing fractionsBenchmarks—identifying and using for comparing and estimatingSimplifying fractionsOperations with fractionsNaming decimal numbers correctlyIdentifying fraction/decimal equivalents, including benchmarksRounding decimal numbersDecimal currenciesOperations with decimal numbers
The graders began their work by thinking of what they remembered about fractions and then creating their own fraction strips.Most found creating the strips more challenging than they expected.






Grade Seven: What are the Chances?

Image
The seventh graders have begun a unit on probability.  It is one of my favorite units to teach because we get to play games and try to understand that sometimes there are ways to increase one’s chances or to see that sometimes a game or situation is going to be a losing proposition, no matter what.
This week, both classes began their first experiments and collected data by flipping coins (many times!).This data will lead us into understanding where the numbers for probability come from and to think about how accurate they might be.In the coming weeks, students will be making predictions and testing them out.  They will learn some methods of organizing results, such as with lists and tree diagrams.  These activities should lead to a better sense of what is “fair” and what is not.




Spring Break!

Image
Spring Break is here!  It is off to a pleasant start and will hopefully remain so.  If you are traveling, I hope you have a safe trip (and that you use some good math thinking).  If you celebrate Easter, I hope you have a joyous holiday.
This afternoon, the Sixth Grade Math 2 class followed up some good discussion of their calendar problem with learning a new game.  Equate is pretty much like a math version of the famous word game Scrabble.




Grade Six: Math 1 Test and Study Guide

Grade Six Math 1 will have its assessment on integers on Thursday, March 29.It will be a test and be assessed using Criterion A: Knowing and understanding.
What should you know? What is an integer?What is an absolute value?Integers on a number lineOperations using integers, including simplifyingProve operations (using a number line or objects)Using exponentsOrder of operationsHow should you prepare? There is a variety of source that you can use.Choose what works best for you.
Your notebook This should be your best study guide.
IXL Problems in Sections M and N are related to integers. T9 is also a good one to look at for differences between integers.It uses a thermometer.The temperatures are in Fahrenheit but that will not affect the thinking you need to do.
Textbook I have not used always explained things the way the textbook does, but the practice problems can be useful.Your textbook calls them directed numbers (because the positive and negative signs tell you which direction to move).Look C…
