Now let’s recall what are the characteristics of a parallelogram.
My principle is that pupils need only informative pictures and figures.
Purely illustrative pictures made for fun,
for example a rat that is looking at what’s going on, will only distract pupils.
Figures and pictures must be relevant to the point.
Now we will talk about the angle of elevation, we’ve already learnt about the slope of a line.
I choose such exercises that I can break into different parts.
So I can train each part separately
and when I’ve done that we can put a complete exercise together.
If I have to construct something in a lesson on the blackboard using chalk
I have to hold the ruler and the set square ,
look at the children over my shoulder and talk simultaneously.
It’s much easier with an interactive whiteboard.
Let’s put the angle on the side we want to push.
Hold the ruler steady
and move only the set square
so that we can plot a line of equal length starting from the opposite vertex.
Pupil answers: „-1/4“. Teacher: „Exactly, well done!“
It’s not the point you put there that you have to plot.
So what now, what should we plot next?
Pupil: „Heights“.
They lie at the end points of the diagonals.
Let’s connect them with the help of a ruler.
I’ve put a number of formulas on the board.
Your task is to choose the right one and
drag it behind the right concept.
Read the question and choose the right answer.
Try it at home as well – the computer will switch the questions.
Pupils: „So where is our million?“
Teacher: „Luckily the prize is 1,000,000 points and not Euros.
I thought that otherwise I have to pay you money here.”
