Add Three Numbers Worksheets for 1st Grade

What your child practices

Add Three Numbers is a key 1st grade math skill (Grade 1 in Canada), and these 50 worksheets add up to 900 questions of practice. In the early grades, number sense grows through lots of short, hands on practice, and Add Three Numbers is one of the building blocks teachers return to all year. Each of the 50 versions of Add Three Numbers has new questions, so your child can repeat the skill without memorizing answers. Each sheet supports Common Core 1.OA.A.2, covering operations and algebraic thinking: adding, subtracting, multiplying and dividing to solve problems. In Canada it matches the BC curriculum for Grade 1. Answer keys sit on page 2 of each PDF, so checking takes seconds. Before printing, try the Add Three Numbers video lesson, then print a sheet while it is fresh.

Tips for parents

• Keep counters, blocks or fingers nearby. Young children learn numbers best when they can touch them.
• Do one sheet, check it with the answer key, then redo only the missed problems the next day.
• Turn one problem into a real life question, using snacks, coins or toys around the house.
