①本范例演示整数加法的交互式练习测验，包含5个题目；②涉及的核心数学概念为整数加法运算规则；③作图要点：使用了Random命令生成随机数，Textfield和If命令显示题目和结果，button1按钮触发计算，对象包括m, b, visible, Minimum, Maximum, a1, b1, s1, text1, r1, InputBox1, textR1, score, r2, a2, b2, s2, r3, a3, b3, s3, r4, a4, b4, s4, r5, a5, b5, s5, text3, InputBox2, textR2, button2, text4, InputBox3, textR3, text7, InputBox4, textR4等；④适合初中数学教学或学生自学练习。
