Simply promote quantity understanding
Again and again apprentices complain that they would like to hire young people if they had only practically applicable knowledge of mathematics and German. The problem is that many people have achieved quite good grades in tests in these subjects for years, but it looks quite different with the applicable knowledge (quantity understanding).
Therefore, it makes sense to create situations in everyday life with children, in which knowledge from the school can also be applied.
Here is an example of quantity understanding (possible from the third class):
Put a packet of flour or sugar (1 kg) on a tray and spread it as evenly as possible. Then the child is to divide different amounts with the knife by cutting the flour or sugar pile with a knife. Such amounts may e.g. be: 500 g, 250 g, 125 g, 750 g. This is more a rough indication (for example, to know that 500g is half of the flour or sugar pile).
Then the flour or sugar can be used for baking. Here you have again a good exercise for dealing with measuring units, since milk, fat, etc. must be measured by prescription.
So one has done something for the practical understanding of mathematics and in the end even has a reward.
