Patterns, primes, and big numbers
Fourth graders explore numbers in big and beautiful ways. They read, write and compare whole numbers up to a million, using symbols like 45,302 > 45,230. They learn that every number is either prime (exactly two factors, like 7) or composite (more than two, like 12), and they find all the factor pairs for numbers up to 100. They also create and extend number patterns that follow a rule, like "add 4" or "multiply by 2." The click comes when kids spot a hidden pattern, like every number in "add 4 starting at 1" being odd, and explain why.
Number sense grows when kids look for patterns and talk about what they see.
Write the start of a pattern on the board, like 3, 7, 11, 15, and have students find the rule and extend it five more terms. Then ask what they notice: all odd! Building and extending patterns turns kids into number detectives.
Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Why it works: a catchy, repeating tune gives the brain a hook to hang words on, so sung text is remembered better (Wallace, 1994).

Why it works: shuffled practice teaches kids to choose the right strategy, not just repeat one, and it improved test scores in research (Rohrer and Taylor, 2007).

A prime number has exactly two factors: 1 and itself. Examples are 2, 3, 5, 7 and 11. The number 1 is not prime because it has only one factor.
A composite number has more than two factors. For example, 12 is composite because its factors are 1, 2, 3, 4, 6 and 12.
Fourth graders read, write, compare and round whole numbers up to 1,000,000. They use place value to understand what each digit is worth.
Show the first few terms, ask students to find the rule and extend the pattern. Then ask what they notice, like whether all the numbers are odd or even, and why.
