Today's Lesson

Today we will learn how to write equations from word problems. Math helps us solve problems and understand the world around us.

An equation is a mathematical statement that says two expressions are equal. It always has an equals sign (=). For example: 5 + 3 = 8 or x + 4 = 10. When an equation has a variable (like x), solving it means finding what number makes both sides equal. Equations are like balanced scales—what you do to one side, you must do to the other to keep it balanced!

Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!

Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.

Key Terms
Word

A group of letters that means something

Practice Problems
1

Solve for x: x + 7 = 15

Hint: Subtract 7 from both sides.
2

Solve for y: 3y = 12

Hint: Divide both sides by 3.
3

If 2x - 5 = 9, what is x?

Hint: Add 5 to both sides, then divide by 2.

Teaching Tip

For younger learners: Use concrete objects and hands-on activities when teaching write equations from word problems. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
