DESMOS – Your new best graphing friend!
Desmos is a great online graphing tool and ideal for teaching and learning at all levels. It is intuitive and really versitile and highly recommended by H3 Maths as “Your new best graphing friend.” Give it a go!
Mac Mouse Magic for Mathematical Memories
A few of us met the Macintosh when it was launched in 1984, and I can still remember a sample being on trial at my first school. Sitting apologetically in the corner of the main staffroom, it was a rather odd looking, all-in-one computer with a strange device attached called a “mouse”. Perhaps that is […]
Tough questions for tough math kids
Think you’re good at maths? Results to the OECD’s ‘Programme for International Student Assessment’ (PISA) are out (December, 2013) and have been causing upset in Western democracies like the US and the UK, whose 15 year olds have scored badly by international standards. The questions in PISA tests are segmented by difficulty, with level 6 questions […]
Global Data heats up…
From 1971 to 2000, the world’s land areas were the warmest they have been in at least 1,400 years, according to a new study inNature Geoscience. The massive new study, involving 80 researchers from around the world with the Past Global Changes (PAGES) group, is the first to look at continental temperature changes over two […]
Graphing altitude, speed and time
Aircraft have to fly the most efficient way in order to maximise profits for the airline. The take-off, cruising altitude and speed, and descent are all carefully calculated mathematically. There are many complex factors at work in flight dynamics. This example shows three related flight parameters (which we looked up as it was a flight […]
Graph Interpretation
Here is a challenge. Can you work out what information is being displayed in this graph? In a previous blog we talked about the fact that every graph tells a story. Of course, sometimes the story is not very clear or obvious but, as a mathematical sleuth, you can make some guesses! Click on the […]
Geometry 101
Here is a great tip to improve your Geometry skills – always add these extra labels to your axes – they will help you solve graphs far more easily!! Trust me, this is another H3 tip that DOES make a big difference in your Mathematics!! Note 1: The y axes has the equation x=0. For […]
Double Stem and Leaf
Double stem and leaf plots are used to compare two distributions side-by-side. This type of double stem and leaf plot contains three columns, each separated by a vertical line. The center column contains the stems. Example – Making a double stem and leaf plot for the data gathered by students doing traffic counts at different times […]
