【Not being able to use a formula for area correctly.】

Calculating an area of basic figure exactly is one of very important lessons at arithmetic class in elementary school.😃

However,there are a lot of children who can't use formulae exactly,for there are several formulae for each figure.It makes the children confuse the formulae.They mistake the formula of circumference 円周 for the one for area of circle.😥

It's not always the children's fault,for grown-ups around them seem to be worried about not using the formulae correctly.They don't try to pay attention to processes which reach the formulae very much.😒

As a result,the children are apt to think about learning plenty of formulae by heart so much that they end up confusing.The phenomenon frequently continues from elementary school to university.😱

When learning area of figures in elementary school,if the children can reach the formulae for themselves,their mathematical abilities will improve in the future.Then the important thing is…💡
