As long as the addition and subtraction within 100 is the main method in the primary stage of junior two mathematics, which is also the first contact of junior two students, the calculation in any stage of mathematics is the basis to be mastered.
Then the study of mathematical knowledge, including some angles, right angles and edges in mathematics. This is also very important, it is the basic learning in mathematics, and it also needs children to master it. Then there is the study of some units, such as centimeters and meters. Because they touch these corners, these units will also be used soon.
Then some simple multiplication learning. At this time, the multiplication formula is also very important. I remember when I was a child, the teacher repeatedly asked us to recite these multiplication formulas. At first, we didn't understand it very well, but later, when we used it, simple calculations in daily life were all based on this, so the multiplication formula must also be memorized. Enlighten our mathematics learning.
There is also the observation of some objects, which students need to learn at this stage. Mathematics is, after all, an abstract subject, and it is also very important for students to observe and learn all kinds of graphics. This can also stimulate students' thinking and thinking.
Finally, the applied problems learned are mainly to cultivate students' understanding ability and thinking ability, which is also a long-term process with mathematics learning.
