базовых тем – «Табличное умножение и деление». Как и любая другая тема, она требует внимательного осмысления и прочного закрепления. Особенностью этого издания является крупный шрифт. Как показывает практика, ученик полностью усвоил тему, если решает пример и записывает ответ в течение 4–7 секунд. В этом случае можно говорить, что навык счета доведен до автоматизма. На каждой странице приведены 6–7 столбиков, в среднем по 35 примеров. В конце столбика записывается время, потраченное учеником на решение. В левом нижнем углу обозначены контрольные цифры: идеальное время решения одного столбика, удовлетворительное и результат, который должен заставить ученика задуматься. Учителю сложно проверить такое количество примеров, поэтому лучше, если время, затраченное на решение каждого столбика, отметят взрослые дома. Чтобы достичь хороших результатов, каждый день нужно решать по одной странице. Пособие можно использовать в качестве дополнительного материала на уроках математики, а также для занятий дома.
