These methods are more convenient for adding small numbers.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">In their quest to master addition, students start by learning how to add one-<a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/number-sense\/digit\" target=\"_blank\" rel=\"noopener\" title=\"\">digit<\/a> numbers using their fingers or the <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/number-sense\/number-line\" target=\"_blank\" rel=\"noopener\" title=\"\">number line<\/a> and then move on to adding bigger numbers using <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/place-value\/place-value\" target=\"_blank\" rel=\"noopener\" title=\"\">place value<\/a> or <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/algebra\/column\" target=\"_blank\" rel=\"noopener\" title=\"\">column method<\/a>.
