  • At first the starter was challenging but then it started to make sense and that was when everyone started to get the hang of it. All together we got all the answers between us. The people who got the first answer were Danny, Ryan, David, Murran, Molly, Bryony, Alicia and sir. And some others got the rest of the answers.

  • A good starter that can be developed easily into a differentiated lesson. For example, use the minumum number of stamps, pairs of stamp values that work for all postage values (1p stamp not allowed!). What sort of pairs work for the fewest values of postage.
  • Set 1 Year 4(Mathematical Whizz Kids! ), Banks Lane Junior School

  • We found three ways to solve this problem by working systematically using multiples of 3 and 8.
    (2x8p)+(19x3p)
    (5x8p)+(11x3p)
    (8x8p)+(3x3p).

  • This is an old idea but still very worthwhile even though the cost of the stamps probably isn't very realistic at today's prices. It lends itself to be extended in a number of ways in addition to those suggested by N Cox above (thanks). Please share any ways of developing this activity that might be useful to other teachers.

Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...
