去年有幸参加了区教研室组织的《一题一课,自主编题》的课堂教学评比活动,也幸运的获得了区一等奖的荣誉,现在把对这堂课的设计和反思在这里和大家分享及交流。这是一道初一的阅读材料题,题目是:阅读下面的材料:1×2=1/3(1×2×3-0×1×2),2×3=1/3(2×3×4-1×2×3),3×4=1/3(3×4×5-2×3×4),由以上三个等式相加,可得1×2+2×3+3×4=1/3×3×4×5=20 Last year, I was fortunate enough to participate in the classroom teaching evaluation organized by the district teaching and research department and won the first prize of the district in a fortunate manner. Now I am here to design and reflect on this lesson Share and exchange. This is a first-day reading material topic titled: Read the following materials: 1 × 2 = 1/3 (1 × 2 × 3-0 × 1 × 2), 2 × 3 = 1/3 (2 × 3 × 4-1 × 2 × 3) and 3 × 4 = 1/3 (3 × 4 × 5-2 × 3 × 4). By the addition of the above three equations, 1 × 2 + 2 × 3 + 3 × 4 = 1/3 × 3 × 4 × 5 = 20
