Money: Adding and Subtracting
This topic covers adding and subtracting money using decimal notation in everyday contexts. Learners will apply these skills to real-life situations.
Assessment criteria
Topic Overview
The Ascentis Entry Level Award in Mathematical Skills (Entry 3) is designed to build foundational numeracy skills essential for everyday life and further learning. At this level, you will develop confidence in working with whole numbers up to 1000, simple fractions, basic decimals, and common measures such as length, weight, and capacity. You will also learn to handle money, tell time, and interpret simple charts and tables. This qualification is ideal if you are starting your maths journey or need to strengthen core skills before moving on to higher levels.
Mastering Entry 3 maths is crucial because it equips you with practical abilities for real-world situations—like budgeting, shopping, cooking, and understanding timetables. It also prepares you for the next step, such as Functional Skills Maths Entry Level 3 or Level 1. The course emphasises problem-solving in familiar contexts, helping you apply maths to daily tasks. By the end, you should be able to perform calculations with confidence and communicate your reasoning clearly.
Key Concepts
Core ideas you must understand for this topic
- →Place value: Understand the value of digits in numbers up to 1000 (e.g., in 345, the 3 represents 300).
- →Four operations: Add, subtract, multiply, and divide whole numbers using mental and written methods, including simple word problems.
- →Fractions and decimals: Recognise halves, quarters, and tenths; understand that 0.5 is the same as 1/2 and 0.25 is 1/4.
- →Measurement: Use standard units for length (cm, m), weight (g, kg), and capacity (ml, l); read scales and compare measurements.
- →Time and money: Tell time to the nearest 5 minutes on analogue and digital clocks; calculate change from £10 and solve simple money problems.

Assessment Guidance
Guidance for achieving higher grades
- 💡Practice with real price tags and receipts.
- 💡Check your work by estimating.
- 💡Use column addition and subtraction methods.
- 💡Show your working: Even if you make a mistake, you can get marks for correct methods. Write down each step clearly.
- 💡Check your answers: Use inverse operations (e.g., addition to check subtraction) or estimate to see if your answer is sensible.
- 💡Read the question carefully: Underline key words like 'total', 'difference', 'share equally' to know which operation to use.
Common Mistakes
Common errors to avoid in your coursework
- Misaligning decimal points when adding or subtracting.
- Forgetting to carry over or borrow correctly.
- Confusing pounds and pence.
- Misconception: 'Adding 0 to a number makes it 10 times bigger.' Correction: Adding 0 to a number (e.g., 5 + 0 = 5) does not change its value; multiplying by 10 moves digits one place left.
- Misconception: 'A bigger denominator means a bigger fraction.' Correction: For fractions with the same numerator, a larger denominator means smaller parts (e.g., 1/4 is smaller than 1/2).
- Misconception: 'When reading scales, always count the number of lines.' Correction: You must identify the value of each division; for example, on a 1 kg scale with 10 divisions, each division is 100 g, not 1 g.
