Sun 6:00 AM - 7:00 AM UTCSep 28, 6:00 AM - 7:00 AM UTC
In this foundational session, we'll start with the basics of what variables represent and practice identifying the parts of algebraic expressions (variables, coefficients, and constants). You'll learn to write mathematical expressions from word problems and work through step-by-step evaluation using substitution and order of operations. We'll progress from simple examples like x + 5 to more complex expressions involving exponents and multiple operations.

Sun 6:00 AM - 7:00 AM UTCOct 5, 6:00 AM - 7:00 AM UTC
In this session, we'll review variables and expressions from our previous lesson, addressing any questions or doubts you may have. We'll then learn to identify and combine like terms to simplify expressions, followed by mastering the distributive property to expand expressions like 3(x + 4). You'll practice connecting these concepts by distributing first, then combining like terms. Expect hands-on activities, step-by-step guided practice, and collaborative problem-solving that builds on your algebraic foundation. By the end, you'll confidently simplify expressions like 2(3x + 1) + 5x into their simplest form.
