This easy worksheet introduces first graders to subtraction within 20 through key vocabulary and gentle teen-number practice. Children begin by tracing six take-away words, including 'minus,' 'less,' 'take,' 'left,' 'away,' and 'fewer,' which builds the language they will see in story problems all year. Four fill-in-the-blank equations such as 14 - 6 = ___, 11 - 3 = ___, and 16 - 9 = ___ ask learners to bridge ten for the first time, while three true-or-false statements like '15 - 7 = 8' and '12 - 4 = 9' encourage careful checking before circling an answer.
