John Mighton: Cool Mathematician

One of the coolest mathematicians that I have met has to be John Mighton. When I first started teaching I worked in an inner-city Toronto School. The kids there hated math. But John changed all of that. He created a program called JUMP math. I was lucky enough to be one of the first teachers’ to use the program. The neat thing about John was that he didn’t even like Math when he was in school. Like me, he didn’t start to like math until late into adulthood. And he’s not just a mathematician! He writes scripts for movies and plays. He’s even an actor. He was the script advisor for a neat movie about a young math genius, titled, Good Will Hunting. One of my favorite parts about working with John Mighton and JUMP Math was the cool volunteers he brought with him. One day Chris Murphy, the lead singer of one of my favorite bands, Sloan, walked in and said he would be the class math tutor for the term! But the best part about working with John Mighton and JUMP Math was that students who didn’t believe they could do math were doing it with ease by the end of the term. I still use JUMP Math today!

Check out John in Action.

Will Frankensteinstorm Effect Halloween?

The news is telling us that a huge storm is on Its way. The Storm is thought to be one of the biggest on record. Some people are calling for Halloween to be moved until the storm passes. Should Halloween be postponed? How could our knowledge of science and math be applied to this problem?

A Tiny Zoo Problem

My favorite game App for my iphone is Tiny Zoo friends. My daughters and I have spent countless hours buying, feeding and taking care of the animals. I love seeing my zoo get bigger and bigger. Yes this is a silly obsession, but hey I like it!

In the game the animals are born and grow at different rates and they only start making you money once they start growing. Here’s a Tiny Zoo problem to think about…

In the Tiny Zoo, a newborn Siberian Tiger weighs 1300g when it is born. It gains 100g a day. A newborn spider monkey weights 3300g when born and it gains 200g every week. Who weighs more after two weeks, who weighs more after 6 weeks? The big question is, which animal needs the most food after 6 weeks? Food costs money! Take it beyond math now. If you were a real zoo keeper how much food would you have to feed these animals, what would you feed them, how much would it cost to feed them? Where would you find the information?

***As always review our learning goal and success criteria.

Math 6: Patterning

Learning Goal

I will be able to identify patterns and their rules to decide if they are increasing or decreasing. I will also be able to make my own patterns and rules using different strategies.

Success Criteria

To achieve my learning goal I can…

·         Use my fingers to add and subtract to find the gap in numbers

·         Use a t-table to find how a pattern is increasing or decreasing

·         Use an input and output machine to create patterns and see what operations are being used
·         Draw and build patterns with concrete materials

·         Make rules to decide if a pattern is increasing or decreasing

·         Use all of my strategies to solve real world problems

Math 7: Could You Manage McDonald’s?

We have been discussing factors and multiples. We have been seeing how numbers have a lot in common, but does this have anything to do with the real world? Let’s take a look.

Learning Goal: I will be able to understand the difference between multiples and factors. I will produce multiples and factors for whole numbers, using a variety of tools and strategies.

Success Criteria:

  • I can start at a number and skip count to find multiples
  • I can use a 100s chart to count up by a number to find multiples
  • I can compare the multiples of two or more numbers, by creating lists and using a 100s chart to identify the Least Common Multiple
  • I can use mental math to find factors of a number
  • I can use a 12×12 chart to find the factors of a number
  • I can use a calculator to divide numbers to find factors
  • I can compare the factors of two or more numbers to identify the Greatest Common Factor
  • I can use my personal device and google, calendars and any other apps that will help me solve real world problems
The Problem
You are the manager of McDonald’s. Kevin, Alison and Fred work part-time at McDonald’s. Kevin works every second day. Alison works every third day. Fred works every fourth day. Today they all worked together, when will they work together again? They need to know so they can drive in together. You need to make a schedule for these three workers. Use any tools or strategies that may work.

Factors and Venn Diagrams

Remember to organize factors by listing numbers in order. Circle all common factors and identify GCF. Remember factors are two numbers that make a product.

Math 7: Factoring

Today we began looking at how numbers can be broken down into manageable chunks. We explored both prime numbers and composite numbers.

Homework: on your chart from class fill in each square until you arrive at 100. When you are done shade in all the prime numbers. Use the math wall for help.
