This hard worksheet sharpens regrouping fluency when answers fall just below or above seven. Four multiple-choice items ask 'What is 12 - 5?', 'What is 16 - 7?', 'What is 11 - 4?', and 'What is 14 - 6?', forcing children to choose between answers that differ by only one. Five fill-in-the-blank equations including 13 - 7 = ___, 17 - 8 = ___, 15 - 9 = ___, 11 - 6 = ___, and 18 - 9 = ___ then test the trickier near-doubles families. Use this page to confirm that bridging ten has truly become automatic before moving on.
