Adding and Subtracting Binomials | Math Lesson

How do you combine algebraic expressions correctly? In this Grade 8 math lesson, students learn how to add and subtract binomials by combining like terms. Using visual models and real-life examples, students see why only like terms can be combined. Algebra tiles help make abstract ideas concrete before students move to symbolic math. The lesson also explores subtraction cases that result in negative values—and why those results still make sense. This lesson builds the foundation for simplifying expressions and solving equations later on. 📚 Aligned with Grade 8 Ontario Math – Algebra ✏️ Learning focus: Adding and subtracting binomials 🔢 Key concepts: Like terms, binomials, algebra tiles Watch now to learn how combining like terms makes algebra clear and logical.
