 «По страницам  математики»

Подготовили учителя начальных классов

Сараева С.А  и Халитова Л

Цели:

Коррекционно-обучающая: активизировать мыслительную деятельность учащихся, закрепить знания счета от 1 до 100; знать место каждого числа в натуральном   числовом ряду ; сравнивать группы предметов по количеству.

Коррекционно-развивающие: интерес к изучению математики, развивать  логическое  пространственное  мышление, воображение, смекалку.

Коррекционно - воспитательная: любознательность, ответственность, воспитывать  уверенность в своих силах, умение работать командой.

Сего́дня мы посостязаемся в смекалке и сообразительности. По̄смо́трим, какие вы   внимательные и находчивые. Жюри будет следить за ходом игры. За каждый правильный ответ команда получает 1 очко.

У нас две команды : команда «плюс» и команда «минус».

Итак, начинаем нашу математическую викторину.

Речевая минутка:
