Addition worksheets for Grade 1

In Grade 1, addition is about getting fluent within 20. Kids start the year adding small numbers by counting on from the bigger one, and by the end they recall most facts to 10 without counting at all. Doubles like 4 + 4 and pairs that make ten are the anchors they lean on for everything else.

Start with sums to 10 at the easy level, where both numbers stay small. When a sheet comes back with few mistakes and no finger counting, move to sums to 20. The medium level mixes facts freely, and the hard level asks your kid to cross ten, for example 8 + 5, which is where the real thinking happens.

Missing addend sheets, like 6 + __ = 10, look like addition but build the idea behind subtraction. If your kid gets stuck, cover the blank and ask what number is needed to finish the ten. A ten frame or ten counters on the table makes this concrete.

Keep sessions short. Ten problems done with attention beat thirty done in a rush. Let your kid check the answer key themselves and circle the ones to try again tomorrow.
