Radar

The aircraft shown are all flying at the same speed and height.

The directions they are flying are shown as three figure bearings.

Is the situation safe or are any aircraft likely to collide?

  • Transum,

  • This is an exercise in estimation assuming that the pupils understand three figure bearings. They need to decide, given the direction of travel, whether any of the aircraft will collide or whether they will safely fly out of the airspace covered by this radar screen. You can see the answer by running the simulation which shows how the situation unfolds. As an alternative way of using this resource you could print out this page and ask the pupils to accurately draw on the flights paths using ruler and protractor. Each time you refresh the page you get a new situation so all of the pupils could be working on a different problem. Remember it is not enough to say two flight paths intersect, the planes need to be at the same place at the same time before a collision takes place. Also when two planes have collided a third plane is safe to enter that position as presumably the collided planes have fallen to the ground.

  • I think this is great. I copied an image before the simulation and after. Students will draw in bearings on a paper based copy and see for themselves whether there is a crash or not.

  • This is such a great starter, thank you! My only request would be to be able to have a few fixed versions, so not all randomly generated - I'd like to print it out and give copies to students, but I can't as they're random!

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.

Teacher, do your students have access to computers?
Do they have iPads or Laptops in Lessons?

Whether your students each have a TabletPC, a Surface or a Mac, this activity lends itself to eLearning (Engaged Learning).

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...


If your pupils' ability to estimate compass bearings is not good enough for this Starter you may want to instead begin with this. It's a whole class practice/learning activity that could be played as a game.
