A manual contains 32 blocks of examples on the basic themes of the program on mathematics for a 1 class.Task of students - to find and correct mistake in examples, and then to write down a faithful example under a column. Depending on the level of complication a student writes down one, two, three examples. Guys with pleasure execute the tasks of such type - in fact each it is offered to visit some time a teacher.It is possible to organize work in pairs and groups:pair work - neighbours on a school desk find and correct errors in examples, write down faithful examples under columns, after change notebooks and check up work of each other|group work - the students of every four alongside standing school desks unite in a group and jointly execute tasks. Aim - to pass other groups.It is possible to conduct a game-competition: Who is quicker? - a student, finding errors first, writes down corrected examples on a board| Agents-mine-layers - it is needed as quick as possible (in a pair or group) to find errors in a column, a few columns, in a level or on all page.Work with a manual allows to fasten the studied material, take skill of account to automatism.A manual can be used on the lessons of mathematics, and also for work of house.More detailed:
