Angle rules - parallel lines


Learning Objective:

  • we are learning to recognise alternate, corresponding and allied angles and use the appropriate angle rules to find missing angles in situations involving parallel and intersecting lines.

Investing:

  • This is useful because...
  • A functional (real-life) application is...
  • This skill leads to...
  • A 'free gift' with this skill is that we can now also...
  • This could help you if you want to work in...

Preparing:

  • You should already know simple angle rules
  • Can you already... ?
  • Let's be sure you can...
  • Before you start you need to know:
  • You will have a deeper understanding if you also know:

Discovering:

  • Can you figure it out yourself from these examples?
  • Try to predict the next one aloud or on a mini-whiteboard.
  • Investigate...

Modeling:

  • Here are some examples of people getting it right:
  • Here are some examples of people getting it wrong in typical ways:
  • Here are some more examples. Did they get it right or wrong? Explain how you know!

Discussing:

  • What would this one be? Tell your learning partner. Convince them you're right.
  • Explain how you know.
  • How would you explain this to someone who was new to it?

Explaining:

  • One way to do this is...
  • Another approach might be...
  • A useful shortcut is to...
  • This works because...
  • It doesn't work when...
  • An exception is...
  • Watch out for...
  • A common mistake is...
  • You can check your result by...
  • We can prove this works by...

Practicing:

  • Some straightforward examples: recognise which rule is being used:

as a PowerPoint as a Qwizdom activity (experimental format - please use a feedback form if you try this)
  • Some harder examples.
  • Some mixed examples.
  • Some non-examples to spot and some mixed questions with redundant, insufficient or contradictory data.
  • You can demonstrate fluency by at least...

Sharing:

  • A web page or wiki I have created to explain this can be found at...
  • A presentation I have created and rehearsed looks like...
  • A poster I have drawn or model I have made can be found...

Assessing:

  • Check you've mastered this skill by...
  • Show you understand by explaining...
  • Prove you're an expert in... by...

Developing:

  • Next we could learn...
  • This leads to...
  • Now try...
