Missing Factors Worksheets for 3rd Grade

What your child practices

This set of 50 worksheets on Missing Factors is written for 3rd grade (Grade 3 in Canada) and gives your child 1050 questions to work through, one page at a time. In grades 3 to 5, math moves from counting to reasoning, so confidence with Missing Factors pays off later in multistep problems, measurement and early algebra. Each of the 50 versions of Missing Factors has new questions, so your child can repeat the skill without memorizing answers. Each sheet supports Common Core 3.OA.A.4, covering operations and algebraic thinking: adding, subtracting, multiplying and dividing to solve problems. In Canada it matches the BC curriculum for Grade 4. Each PDF includes its own answer key on page 2, ready for you or your child to check. Short on time? Start with the Missing Factors video lesson, then print a sheet while it is fresh.

Tips for parents

• Encourage your child to show their work. In grades 3 to 5 the method matters as much as the answer.
• 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.
