A six-year-old who knows 9 – 6 = 3 by heart may still pause at 49 – 6, as if the bigger number changed the rules. It does not, and this 1st grade two-digit minus one-digit worksheet lets your child discover that. Eight colored boxes each hold one problem in tens and ones columns, with a two-digit number on top and a single digit below. The problems range from 29 – 9 to 98 – 7, and one of them, 61 – 0, takes nothing away at all. None needs regrouping. Your child writes each answer under the line. A girl holding a cat smiles from the corner. A second page gives the answer key.
