教学反思：
本课的课题是shapes， 对象是五年级的学生。鉴于五年级的学生已经有了一定的动手能力和自主思维能力， 我在这堂课中设置了不少同桌协作和动手操作的环节， 以次提高学生的合作能力和独立思考的能力，并尽量使所学知识与实际靠拢， 尽可能多的利用实物进行单词和句型的操练。整节课的宗旨是， 将说的机会尽量让给学生。除了一些必要的示范， 我通过暗示，引导等方法让学生尽可能多说，多思考，多表现，有效地激发了他们学习的热情和表现的欲望，并很大程度上锻炼扩展了他们的思维，并在一定程度上提高了他们的动手能力。很好的体现了小学英语兴趣性活动型和生活性的原则，在实施教学的过程中充分体现学生是学习的主体，调动了学生的积极性。
学生此节课动手又动脑，加上还有实物与图片的辅助，从而使学生的兴趣和积极性得到了很好的调动，师生之间得到了很好的交流和沟通，因此学习的氛围相当不错，学习的效率变得很高。此外，一些适当的课外拓展既是对学生知识的一种补充，又扩大了学生的知识面，生活与实际紧密结合，使学生知道生活中处处都有知识。
