Times Tables and Incentive Charts
I normally use a hundred grid sticker chart for kids to track their progress. It serves multiple purposes because you can have (say) a silver star for every third sticker, and then you get a pretty pattern which doubles as a representation of a multiplication table.
Recently I came across this wonderful multiplication pattern from Burkhard Polster, so I thought I would try it out as an incentive chart. The kids love it because, even though it... is beautiful, they have no idea what it is going to end up looking like. So now, instead of getting a sticker, they are allowed to draw a line - which also teaches them how to use a ruler accurately!
Maths Games Contest 1 - 17 May
This is our 3rd Year of the Maths Games and we are expecting over 13000 students will participate in the first contest this week.
Good luck to everyone involved. We hope that you enjoy the challenge of creative problem solving.
Mathematical Mother's Day Craft
14 May is Mother's Day, and what mother would not be impressed by a rose that converts into its own gift box? This origami project uses simple folds, with angles of 90 and 45 degrees. Each rose requires six squares of paper (three green, and three of the petal colour). Angles, fractions, nets, and lots of other good stuff can be covered in this activity.
Don't miss Eddie Woo on Australian Story - Inspiring!!
We applaud you Eddie Woo. Your approach to teaching maths is inspiring and supports our philosophy at APSMO that all students should have the opportunity to understand and appreciate the real-world application of maths, especially through creative problem solving.
If you missed Australian Story last night then we encourage you to watch Eddie's story of passion and commitment to the art of teaching maths....
The Softest Finest Wool
Australia produces some of the finest wool in the world. The fineness of the fibre is measured in microns. This chart from http://www.learnaboutwool.com/…/Secondary_Wool-The-Fibre.pdf shows you the wool grading system. Could human hair be graded using the same system?
Snappy the Crocodile
Tony is showing people little Snappy who is 20 months old and 900 mm long. Tony says Snappy's grandfather Krys (shot in Queensland in 1958) was over 8 m long according to this old photograph of him. Tony asked Amanda to step out 8 m from Snappy so we could see how long this is. Could Snappy ever get to be this long? By what percentage would Snappy need to grow?
The Backyard Pumpkin Competition
Here are photos of the first and second prize-winning pumpkins in this year’s Royal Easter Show. Could you estimate their circumference? At the website http://www.cornect.ca/chart01.jpg there’s a chart relating the weight of a roundish pumpkin to its circumference but notice that the units are pounds and inches (not kg and cm). Also, the equals sign is used incorrectly. More information about estimating the weight of a big pumpkin can be found at http://www.bigpumpkins.com.
Lessons from the AWDRI
If you get a chance to see the Kelpies from AWRDI (Australian Working Dogs Rescue International) jumping over walls, you're in for a treat. Carey Edwards says some gems that relate to teaching mathematical problem solving as much as they do to training dogs like Nimble and Dozer to jump over walls.
Some of his tips are:
- Give rewards even for failure because attempting the jump is the most important part....
- Don't just build the jump up plank by plank. Dogs who can do the low jumps easily get bored and tire before they get to the more challenging jumps.
- Celebrate the success of every dog doing its personal best.
