Mothers may wish to try their children's math addition and subtraction games to improve their interest in learning math. Because after investigation and study, learning mathematics through children's mathematical addition and subtraction games will improve children's mathematical interest and calculation application ability to a certain extent. For example, the game: crack the password? Break into the castle (1) and use the problem package to complete the calculation 1. We came to the castle gate together? First of all? I saw such a set of problems. 2+4 3+512+413+5 2+1512+1413+/kloc-. 2. Can children do calculations? And talk about the calculation method. (2) Do the problem package? Found the rule 1, and showed the problem package16-8 = 814-5 = 915-7 = 816-7 = 913-5 = 8/. (2) Through calculation, students find that the results are always 8 and 9, and the rule in the problem package is that the minuend (or minuend) increases, and the minuend also decreases (or increases) accordingly, and the difference remains unchanged. Such games can not only improve children's learning, but also let them enjoy the fun of the game. Interest in mathematics learning is the forerunner of children's mathematics learning and the spiritual force to promote mathematics learning. Lack of interest in learning often makes children regard learning mathematics as a kind of coolie, which leads to the decline of mathematics academic performance. According to relevant investigation and analysis, one of the main reasons why children become "poor students" in mathematics is that they lack interest in learning mathematics, think mathematics is boring and even hate it. In order for children to learn mathematics well and have interest in mathematics learning, we must first ensure that mathematics teaching is interesting and attractive to children.
