Teaching content: PEP mathematics second grade on the first 68 ~ 69 pages. Teaching process: First, the situation into 1. (Show picture: children take the building blocks of the situation) Look, children take a variety of shapes of the building blocks, more beautiful! The children take a rectangular parallelepiped, take 7 each floor, a total of 2 How do you figure it out? Who can tell the seven multiplication formulas back to you? (Name reply) 2.
