Understand a variable as a symbol for an unknown number.Evaluate expressions by substituting a value.Identify the coefficient of a term.Write simple algebraic expressions.📚 Quick Recap
A variable is a letter that stands in for a number we don't know yet, or a number that can change. Variables are what let math describe patterns instead of just single facts.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1If x = 8, then x + 12 = ?
2If y = 3, then 6y − 1 = ?
3The coefficient in the term 7y is:
4If a = 10, then 2a + 5 = ?
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5A letter that stands for an unknown number is called a .
6The number multiplying a variable is the .
7If x = 8, evaluate x + 12.
8If y = 3, evaluate 6y − 1.
9If a = 10, evaluate 2a + 5.
🚀 Section C · Challenge ● CHALLENGE 5
10What is the coefficient in the term 7y?
