What is the focus of mathematics study in the second semester of grade two in primary school?
Main research:

The multiplication and division in the table, the reading and writing of numbers within ten thousand, the addition and subtraction of numbers within ten thousand (without carry and abdication) include the two-step calculation of addition, subtraction, multiplication and division and the understanding of brackets, that is, the elementary arithmetic rules of simple two-step calculation.

Simple application of two-step calculation. Others are statistics and preliminary understanding. You can use a square to represent five or 10. The simple understanding of graphics and the simple understanding of measurement units such as meters and centimeters of length, kilograms and grams of weight is relatively simple.

Pay attention to the memory and application of multiplication formula, and do simple application problems of multiplication and division in table, two-step calculation algorithm and two-step calculation.
