How to Combine Like Terms and Simplify Expressions in Class 5 Maths
FAQs on Simplify Algebraic Expressions: Practice Worksheet for Class 5
1. How do you simplify expressions for Grade 5?
To simplify an algebraic expression in Grade 5, you mainly combine parts of the expression that are alike. This process makes the expression shorter and easier to understand.
- Combine Like Terms: Add or subtract terms that have the same variable (e.g., 3x + 4x = 7x).
- Group Similar Items: Rearrange the expression to place all like terms next to each other.
- Perform Operations: Carry out the addition or subtraction on the numbers in front of the variables.
- Final Answer: Write the simplified expression in its shortest form.
2. What is an algebraic expression class 5?
An algebraic expression for Class 5 is a mathematical phrase that includes a mix of numbers, variables, and operation signs. It represents a value that can change depending on the variable.
- Variables: These are letters (like x or y) that stand for an unknown number.
- Constants: These are fixed numbers (like 5 or 9).
- Operations: These are signs like addition (+), subtraction (-), multiplication (*), and division (/).
For example, in the expression 4a + 7, 'a' is the variable, '4' and '7' are constants.
3. How do you combine like terms?
Combining like terms is a fundamental step in simplifying algebraic expressions where you add or subtract terms that have the exact same variable part. Think of it as grouping similar objects together.
- Identify Like Terms: Find terms with the same variable raised to the same power (e.g., 5y and 2y are like terms, but 5y and 2y² are not).
- Add or Subtract Coefficients: Perform the operation on the numbers in front of the variables.
- Example: In the expression 8b + 3 + 2b, the like terms are 8b and 2b. Combining them gives 10b, so the simplified expression is 10b + 3.
4. What are the steps to simplify an algebraic expression?
Following a clear set of steps is the best way to simplify any algebraic expression correctly. These steps help you organise your work and avoid mistakes.
- Identify the terms: Look at all the parts of the expression separated by + or - signs.
- Group like terms: Rearrange the expression to put all terms with the same variable together.
- Combine like terms: Add or subtract the coefficients (the numbers) of the like terms.
- Simplify constants: Perform any calculations on the numbers without variables.
- Write the final expression: Present the result in its most compact form.

9. How do you teach simplifying expressions to a 5th grader?
Teaching a 5th grader to simplify expressions is most effective when you use simple, relatable examples and hands-on practice. Start with the basics and build up gradually.
- Use Analogies: Explain combining like terms by using objects, like '3 apples + 2 apples = 5 apples' (3a + 2a = 5a).
- Start Simple: Begin with expressions that only use one operation (e.g., only addition).
- Provide Worked Examples: Show a step-by-step solution before asking the student to try.
- Use Worksheets: A printable algebra worksheet offers focused practice on this specific skill.
10. Why are brackets important in simplifying expressions?
Brackets (or parentheses) are crucial in algebra because they tell you the order of operations. They indicate which part of an algebraic expression must be solved first.
- Prioritising Calculations: According to rules like BODMAS/PEMDAS, any operation inside brackets is always performed before operations outside the brackets.
- Avoiding Ambiguity: Brackets remove confusion in complex expressions, ensuring there is only one correct way to solve the problem.
- Example: In 5 * (x + 2), you must first consider the value of x + 2 before multiplying by 5.
