本文以九年义务教材开辟的“猜一猜”专栏为例 ,浅谈在处理这些习题时如何加强培养学生的数学素养。一、培养运算能力运算能力 :掌握一定的算理 ,寻求合理、简捷的运算途径。例 1 .看下面几个算式 :2 1× 2 9=60 9;2 3× 2 7=62 1 ;2 5× 2 5=62 5。注意到每个式子左边的两个因
This article uses the “Guess Guess” column opened up by the nine-year compulsory textbooks as an example to explain how to strengthen students’ mathematics literacy in dealing with these exercises. First, the ability to develop computing capabilities: to master a certain number of calculations, to seek a reasonable and simple calculation methods. Example 1. See the following formula: 2 1 × 2 9 = 60 9; 2 3 × 2 7 = 62 1 ; 2 5 × 2 5 = 62 5. Notice the two causes to the left of each formula
