【How to understand a knack コツ of being carried up and down 繰り上がり、繰り下がり】

In this way,the two numbers of which sum is 10 is an important way of thinking.If children rely on only a way of counting numbers with their fingers,or they are confused with the difference of the easy equation between ｱ and ｲ or ｳ and ｴ,they'll find it hard to have a good command of the way of thinking the two numbers of which sum is ten.😥

It seems to be important for parents to lead their children in order to understand the way of thinking earlier.👶

Without difficulty,few children can understand the way of thinking of being carried up and down.When making the children understand,small tools which show them real numbers are effective,I'm sure.😃

To tell the truth,I've never thought it difficult to grasp the way of thinking of being carried up and down.I'll never be able to make the children understand without understanding the way of thinking the two numbers of which sum is 10.😳
