Prime factorization (and factor strings) are all about breaking a number down into the prime numbers (or for factor strings, any combination of possible factors to create a product) that make up a number. An example: 30 is a composite number. It can be made in any number of ways 1 x 30, 2 x 15, 3 x 10, 5 x 6 OR 2 x 3 x 5. With larger composite numbers (like 240), there are many more possibilities (like 2 x 120, 2 x 12 x 10). I told them prime factorization is like taking a Lego model apart into all its little pieces.
The picture below shows what they are doing for bellwork this week. It is practicing Order of Operation skills. Since they will be moving into Algebra within a few years, I make them show all the steps they use (GOOD HABITS START EARLY).
