What Grade 6 algebra starts with
Grade 6 algebra begins with a simple idea: a letter can stand for a number. From there, students learn to read expressions, replace variables with values, combine like terms, and solve equations by undoing operations.
Expressions and equations are different
An expression does not have an equals sign, so it can be simplified or evaluated. An equation has an equals sign, so it can be solved by finding the value that makes both sides equal.
How to use this algebra path
Start with the introduction lesson for vocabulary and simple examples. Then use the equation-solving lesson for detailed inverse-operation steps, checks, and word problems.
