5th Grade Mathematics — Pre-Algebra Foundations — Order in God's Creation
Students will learn to solve one-step equations using addition, subtraction, multiplication, and division.
An equation is a math sentence that uses an equal sign (=) to show that two things have the same value. For example, x + 5 = 12 tells us that some number plus 5 equals 12.
To solve an equation, we find the value of the variable that makes the equation true. For x + 5 = 12, we subtract 5 from both sides: x = 7. We can check: 7 + 5 = 12. ✓
We use inverse operations to solve equations. Addition and subtraction are inverses. Multiplication and division are inverses. If 3n = 15, we divide both sides by 3: n = 5.
Just as God reveals truth to those who seek Him, solving equations reveals the unknown number hidden in the problem. Math rewards careful, patient work — just as God rewards faithful seeking.
Solve these equations and check your answers: (1) x + 8 = 15, (2) n - 4 = 9, (3) 5y = 35, (4) m ÷ 3 = 6. Then write two of your own equations and trade with a partner to solve.
