3000 examples in mathematics. 1 class. Find a mistake. Three levels of complexity

The manual contains 32 examples of examples on the main topics of the Mathematics program for grade 1.
Students" task is to find and correct the error in the examples, and then write down the right example under the column. Depending on the level of complexity, the student writes one, two, three examples. The guys are happy to carry out tasks of this type-after all, everyone is invited to stay by a teacher.
You can organize work in pairs and groups:
Party work-neighbors on the desk find and correct errors in examples, write down under the columns True examples, then change by notebooks and check each other"s work,
group work - students of every four next to the desktop desk combine in the group and jointly perform tasks. The goal is to get ahead of other groups.
You can hold a game-media:
"Who is faster?" -A student who found the first mistakes writes the corrected examples on the board,
"reconnaissance-modes"-you need to find errors in the column, several columns, in level or throughout the page.
Work with the manual allows you to fix the material studied, bring the account skill to automatism.
The manual can be used in mathematics lessons, as well as for the work of the house
