Prime or Composite? Worksheets for 4th Grade

What your child practices

Looking for 4th grade math practice on Prime or Composite (Grade 4 in Canada)? Here are 50 worksheets with 1050 questions in total. In grades 3 to 5, math moves from counting to reasoning, so confidence with Prime or Composite pays off later in multistep problems, measurement and early algebra. Each of the 50 versions of Prime or Composite has new questions, so your child can repeat the skill without memorizing answers. Each sheet supports Common Core 4.OA.B.4, covering operations and algebraic thinking: adding, subtracting, multiplying and dividing to solve problems. In Canada it matches the BC curriculum for Grade 6. Each PDF includes its own answer key on page 2, ready for you or your child to check. Before printing, try the Prime or Composite 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.
