数学教学是数学活动的教学,儿童的数学活动就是让儿童充分经历“数学化”。作为儿童数学活动的承载体,活动单能有效地引领儿童主动从事数学实验、猜测、验证、推理、计算、证明等数学活动,这就是“活动单导学”。数学教学中,教师要精心设计活动单,引领儿童进行“数学化”的活动。 Teaching mathematics is a teaching of mathematics activities. Children’s mathematics activity is to make children fully experience mathematics. As a carrier of children’s mathematics activities, the activity list can effectively lead the children to take the initiative to engage in math experiments, guesswork, verification, reasoning, calculation, proof and other mathematical activities, which is “activity guide ”. In mathematics teaching, teachers should carefully design activity sheets and lead children to carry out activities of “mathematics”.
