一年级数学解决“看图列算式”问题的几种类型解答
一、减法问题(1)这样的问题有虚线,但是没有明确去掉的是哪一边的,所以通常情况下是要写两道减法算式的。两道算式都要先数出总数是多少,再减去左边部分,得到右边部分—6-2=4;总数减去右边部分,得到左边部分—6-4=2。(2)这类的问题有明确的指示,虚线和斜线都表示拿走去掉的意思,这里虚线圈走的部分和斜线划掉的部分都表示从总数中去掉了一部分,这种情况只能写一道算式,但是要强调的是一定要用物体的总数来减,学生容易写成用剩下的部分减拿走的部分。算式应写成: 10-4=6 8-3=5(3)这类问题有大括号和小问号提示你,问题问的是什么(有时问的是左边部分有多少,有时问的...
