三年级上册数学进位乘法口算题
进位乘法是小学数学中一个重要的概念，主要涉及多位数与多位数相乘时的进位处理。
这里提供几个适合三年级学生的进位乘法口算题目：
1. 24 × 13
首先计算 24 × 3 = 72，然后计算 24 × 1（同时向左移动一位，因为是十几位），得到 240。
最后将两个结果相加，72 + 240 = 312。
所以，24 × 13 = 312。
2. 42 × 35
首先计算 42 × 5 = 210，然后计算 42 × 3（同时向左移动一位），得到 1260。
最后将两个结果相加，210 + 1260 = 1470。
所以，42 × 35 = 1470。
3. 36 × 27
首先计算 36 × 7 = 252，然后计算 36 × 2（同时向左移动一位），得到 720。
最后将两个结果相加，252 + 720 = 972。
所以，36 × 27 = 972。
4. 58 × 46
首先计算 58 × 6 = 348，然后计算 58 × 4（同时向左移动一位），得到 2320。
最后将两个结果相加，348 + 2320 = 2668。
所以，58 × 46 = 2668。
这些例子都是进位乘法的基本形式，学生可以通过这些练习来掌握进位乘法的技巧。
