Our Solve Expressions using Parenthesis/Brackets lesson plan teaches students how parentheses and brackets are used in mathematical expressions and equations. During this lesson, students are asked to use exactly four 4’s to form every integer from 0 to 10, using only the operators +, -, x, ÷, (parentheses), and [brackets]. Students are also asked to solve practice problems that include brackets or parentheses, demonstrating their understanding of the lesson material.
At the end of the lesson, students will be able to use parentheses and brackets in evaluating numerical expressions containing these symbols.
