Картотека по математике (3 класс) на тему: Карточки по математике 3 класс тема » Табличное умножение и деление»
«Карточки-тренажёры по математике в 3 классе»
Одна из важнейших задач обучения младших школьников математике – формирование у них вычислительных навыков, основой которых является осознанное и прочное усвоение приёмов устных и письменных вычислений. Их усвоение происходит в результате длительного выполнения тренировочных упражнений. Уже несколько лет в своей работе я использую карточки, которые составила по темам: «Таблица умножения и деления», «Сложение и вычитание», «Умножение и деление».
Если в классе 15 учащихся, то и заготавливаю для каждого карточку. Сначала это совместная работа на уроке: устно «по цепочке». Провожу в виде игр:
1. «Пассажиры»
Ученики «по цепочке» решают примеры по карточке. Если ответ ученика – неверный, то наехал на кочку.
2. «Футболисты»
Делимся на 2 команды, неверный ответ – гол.
3. «Рыбаки»
Карточка с примерами – это удочка, сколько ученик решил примеров правильно, столько он поймал рыбы.
4. «Хоккеисты»
Карточка – это хоккейное поле, сколько правильных ответов – столько забитых голов.
Такая работа по карточке оживляет устный счёт и способствует выработке навыков беглого счёта. У ребят создаётся определённый эмоциональный настрой.
Затем провожу индивидуальную работу с учащимся – зачёт. Зачёт проходит индивидуально во внеурочное время. Эта работа позволяет повысить интерес учащихся к уроку, проверить знания у учащихся, индивидуально подойти к каждому ученику в классе.
Эти карточки я использую в течение года много раз, даже при проверке скорости счёта (счёт в столбик).
Работа по карточке способствует не только формированию вычислительных навыков, но и воспитанию привычки контролировать собственную деятельность.
