Math Strategies for Adding Two-Digit Numbers

Miss Oates presents a math review video focusing on adding several two-digit numbers. The video covers various strategies such as making a ten, making a hundred, stacking, adding two then one, and using base 10 blocks. Each strategy is explained with examples, and students are encouraged to practice using these methods. The video aims to enhance students' understanding of addition through place value and properties of operations.
