A number pattern follows a rule, and a fourth grader finds the rule and uses it to write the next term. Each sheet shows ten patterns with one blank at the end: adding the same amount, taking the same amount away, multiplying by the same number, and at the top level a rule with two steps in turn. Your child writes the next number on the line.
What your child will learn
Find the rule in a number pattern
Write the next term
Use add, subtract and multiply rules
Common Core standard: 4.OA.C.5
Worked example
5, 15, 25, 35, ____: each term is 10 more, so the next number is 45.
Common mistake
Looking only at the last two numbers when the rule changes, or adding when the pattern multiplies.
Helpful hint
Subtract the first term from the second, and the second from the third. Are the differences the same?
