![]() Give your students a sense of 'steepness' by showing this short video of someone cycling up a road with 38% gradient. Incidentally, 25,000 balls of chocolate are rolled down this 350m-long street in an annual charity Cadbury Jaffa Race. But we usually prefer to state gradient ratios in the form 1:n, so in this case the gradient is 1 in 2.86. We could write this as the ratio 35:100, simplified to 7:20. ![]() So how can we interpret this gradient? It means we go up 35 units for every 100 units we go across. There are some impressively steep roads in San Francisco but New Zealand boasts the 'world's steepest road' according to the Guiness Book of Records - Baldwin Street in Dunedin has a gradient of 35%. Normal Distribution: short contextual exercises Should We Send Out a Certificate? and Do You Fit In This Car?.Describing Data Sets with Outliers and Identifying Outliers are about outliers and skewness in data (see my related post on teaching skewness). Data: These activities on Haircut Costs and Speed Trap focus on comparing box plots.I also like this short Titanic activity on independence. Probability: the card activity Describing Events is an excellent introduction to probability and the activity Venn Diagrams and the Addition Rule is good too.Discrete Random Variables: a short activity Sounds Really Good! (sort of) which features a real-life use of expectation.Includes calculating a correlation coefficient, interpreting a regression equation and considering causality and outliers. ![]() Correlation and Regression: a lovely activity on coffee shops and crime.Illustrative Mathematics has some fantastic ideas for teaching S1. I've focused on A level because that's where I think it's hardest to find interesting teaching ideas. ![]() I haven't had a chance to look at all these websites yet, but here's some of my top resource recommendations from the websites I've looked at so far. Ooh, new websites! Heaven for a resourceaholic. William Emeny recently posted a link to 'Mathematics 101: Leading Sites for Math Teachers' on his blog. So it's helpful when someone does the searching, filtering and classifying for us. And they're right - there's so many resources to choose from, no-one has the time to look at them all. It became a bit of an obsession! Unfortunately my colleagues found it all rather overwhelming. I started spending a lot of time looking for resources online and sharing these resources with colleagues. I work in a grammar school where pupils respond quite well to didactic teaching styles and textbooks exercises - arguably there's nothing wrong with this approach, but the lovely Trigonometry Pile Up worksheet reminded me that the internet is full of engaging resources and exciting teaching ideas. It all started when I saw a PGCE student photocopying this Trigonometry Pile Up activity from. Yes, I confess, I'm utterly addicted to searching the internet for maths teaching resources. Related resources include answers to all of the cards and test books and answers.'Hello. It became a complete individualised scheme based around a network of activity cards and assessments. SMILE (Secondary Mathematics Individualised Learning Experiment) was initially developed as a series of practical activities for secondary school students by practising teachers in the 1970s. This SMILE resource contains three packs of games, investigations, worksheets and practical activities supporting the teaching and learning of area and perimeter, from calculating area by counting squares to finding the formula for the area of a trapezium.Īrea and Perimeter pack one contains fourteen work cards with a wide variety of activities covering finding areas by counting squares, finding the length of perimeters by counting, developing the formula for the area of a rectangle, drawing different shapes with a given perimeter, finding different shapes with a given area and finding the area of simple compound shapes.Īrea and Perimeter pack two contains eleven work cards with activities requiring students to make shapes of a given size using pentominoes, investigate the area and perimeter of rectangles, find the area of a right-angled triangle, calculate the area of polygons drawn on square dotted paper, investigate different ways of shading half a square, find the area of a triangle, find the area of compound shapes made from rectangles and find the area of a parallelogram.Īrea and Perimeter pack three contains eleven work cards with activities in which students investigate the connections between the area of a parallelogram and the area of a rectangle, the area of obtuse-angled triangles, further parallelogram problems, finding the area of a polygon, finding the area of a trapezium and calculating the area of irregular shapes.
