 1 | OK, Step 3, let’s use this information and draw this diagram | dK1 | Locate | Expression | Suggest | Activity |
 | [draws right angle triangle] | K1 | Draw | Diagram | Impart | Knowledge |
[labels sides and angles] | Â | Write | Labels | Â | Â | |
 2 | OK, Let’s label angle L as theta. | dK1 | New | Teacher | Suggest | Activity |
[Step3: Label L - L = ø] | K1 | Write | Expression | Impart | Knowledge | |
[labels angle with L and ø] |  | Write | Labels |  |  | |
 3 | Step 3: Write down all the information that is given in the question. And put all this information into a diagram. | K1 | Recast | Expressions, Diagram |  |  |
[points to diagram] | Â | Point | Diagram | Â | Â | |

 4 | Step 4. | K1 | New | Teacher |  |  |
[Step 4:] | Â | Write | Note | Â | Â | |
 5 | Since this is a trigonometry question we’re going to | dK1 | Classify | Text | Direct | Activity |
write down all the trig ratios related to the question. | Â | New | Teacher | Impart | Knowledge | |
[points to diagram] | Â | Point | Diagram | Â | Â | |
 6 | We’ll write down sine theta, cos theta and tan theta. | dK1 | Restate | Lesson | Direct | Activity |
[lists on fingers] | ||||||
 7 | So looking from the sine of theta, | K1 | Restate | Move | Direct | Perception |
[Sin ø =] |  | Write | Expression |  |  | |
sine theta is equal to | Â | Rephrase | Expression | Impart | Knowledge | |
[points to diagram] | Â | Point | Diagram | Direct | Attention | |
opposite | Â | Restate | Lesson | Impart | Knowledge | |
[points to opposite line] | Â | Point | Diagram | Direct | Attention | |
divided by hypoteneuse. | Â | Restate | Lesson | Â | Â | |
[points to hypoteneuse] | Â | Point | Diagram | Direct | Attention | |
 8 | Therefore MN | K1f | Read | Label | Model | Reasoning |
[Sin ø = MN] |  | Write | Expression |  |  | |
divided by | Â | Rephrase | Expression | Â | Â | |
[points to hypoteneuse] | Â | Point | Diagram | Invite | Attention | |
hypoteneuse | Â | Restate | Lesson | Â | Â | |
[Sin ø = MN/9.2] |  | Write | Expression |  |  | |
which is 9.2. | Â | Rephrase | Label | Â | Â |
