Number Patterns: what children learn
Third graders look for a rule in a pattern and use it to find what comes next. The steps here reach 100, so children practice adding and subtracting tens and hundreds within the pattern.
Number Patterns: worked example
125, 150, 175, 200, __ 225
Each number is 25 more than the one before it. 200 + 25 = 225.
Number Patterns: a common mistake to watch for
Kids sometimes use the jump from only one pair of numbers without checking that the other pairs match.
Number Patterns: how to help at home or in class
Make a pattern a real story: a savings jar starts with 40 dollars and gains 15 more each week, giving 40, 55, 70, 85. Ask your child to find the jump, then say what the jar holds three weeks later. Try a falling pattern too, like a countdown that loses a set amount each day. When a child can name the jump and extend a list either direction, order of operations is next.
