Addition and Subtraction of Rational Numbers: Part 1
Addition and Subtraction of Rational Numbers: Part 1
This lesson involves using pattern blocks to model addition and subtraction of positive mixed numbers for randomly generated numeric expressions.
- Students will use interactive models and pattern blocks to model positive mixed numbers and the sums and differences of positive mixed numbers.
- Students will understand subtraction of mixed numbers as adding the additive inverse.
- rational number
- equivalent fractions
- mixed numbers
This lesson involves using pattern blocks to model addition and subtraction of positive mixed numbers for randomly generated numeric expressions.
As a result, students will:
- Use pattern blocks to model addition and subtraction of positive mixed numbers.
- Calculate sums and differences, and use the TI-Nspire to check the accuracy of their calculations.
