Is there a memorable way to recite math 8+2 8+3 to 8+ 10 in the first grade of primary school?
Mathematics is not rote learning. Let the children understand the truth.
The calculation of 8 addends allows children to use the method of ten: divide the following addends by 2 and 8 to get ten, and then add up the rest. For example, calculate 8+3, divide 2 and 8 by 3 to get 10, and add the remaining 1 in 3 to get 1 1.
