Ch 4 SUMMARY
+ This time we are going to make the SUMMARY together.
+ No ipads or books on the table, only:
a pencil, pen, geo, eraser

#### Slide 3 -Slide

How ?

+ Finally you get back your own work and you'll see how good or bad you made it!

part 1

#### Slide 5 -Slide

Draw the lines p and q with your pencil and geo, that are parallel.
Draw the line r, that is perpendicular to p and q.
Draw all the lines in one picture!
Use your GEO in the right way!

#### Slide 26 -Slide

It is time to CORRECT your work!
In fact, by exchanging your work with somebody else,
everybody correct somebody else work!

#### Slide 27 -Slide

CORRECTION - 1:
Time to Exchange your Work with somebody else!
+ Now the Solutions follow.
+ Check on the Work you have before you.
+ Do this with another color pen or pencil!

#### Slide 28 -Slide

CORRECTION - 2:
+ Give one point for a Task done good. Wrong? No point.
+ Sometimes you may give half a point. Be fair.
+ Finally, write down a TIP and a TOP,
after having checked on all answers.

#### Slide 29 -Slide

CORRECTION - 3:
Give a starting point too. Why?
There are 9 points to be won, so with one starting point
you could score a 10!

#### Slide 34 -Slide

Checking Solutions 5, 6 and 7
+  These Tasks everybody did a little differently,
so there is no fixed Solution.
+  You just Check on the answers by:
Measuring the Distances and the Angles carefully and Compare to the               results written down by your neighbour!

timer
3:00

#### Slide 35 -Slide

Every one of you has drawn another angle of course.
So we cannot check with precision.
However here's one important check:
+ if the angle is acute, then the result should be between 0 °   and  90 °.
+ if the angle is obtuse, the result should be between 90 °  and  180 °.

#### Slide 39 -Slide

Finally ...
+ totalise the points (=add up),
+ write down a tip (piece of advice), finally
+ hand back the Test to the 'maker'.
+ after this hand back the test to your teacher,
who also have a close look at it, at home
+ you will get back this Formative Test!

#### Slide 40 -Slide

Remember ...

How few or how many points you gained,
most important is that you learned a lot this lesson!

#### Slide 41 -Slide

Opinion ...
Give your opinion of this long lessonup:
+ I learnt something (=de moeite waard), raise 2 fingers
+ I learnt a lot, raise 3 fingers
+ I learnt nothing, raise 1 finger only
