Why success in pre-algebra matters
- One Number, Many Names—Explore the different representations of rational numbers to provide the flexibility allowing young mathematicians to participate in conversations about the best ways to solve important problems.
- Numbers and Their Opposites—Focus on integers and help students make sense of the algorithms for adding, subtracting, multiplying and dividing positive and negative numbers.
- Multiplying and Dividing Fractions to Solve Problems—Help students understand the why and how of multiplying and dividing fractions.
- Making Sense of Proportional Reasoning—Address the relationship between numbers as displayed in ratios and proportions. Focus on the importance of developing proportional thinking with strategies that relate it to its many applications with percent, scale drawings and finding unit cost. Also look at the relationship between sets of numbers in data tables in preparation for linear algebra.
