Notes to Instructors on Content
- Number theory topics that are often covered in chapter 1 are placed with fractions in chapter 3 where the skills will be used. Primes and divisibility rules are placed with reducing fractions. The least common multiple is placed with adding and subtracting fractions. You may reorder this if you wish.
- Portland Community College places integers after whole numbers and before fractions. This is to give students more time to practice their sign rules and to practice them with fractions and decimals. You may reorder this if you wish, but note that there are negative signs in the fraction and decimal chapters.
