📚 Detailed Explanation of Addition Facts – Sums up to 20

Addition facts are all about knowing the answers to adding two numbers together quickly and easily. For Year 2 pupils in Key Stage 1, learning addition facts up to 20 means you can add two numbers that make a total of 20 or less. For example, 8 + 7 = 15 or 12 + 6 = 18.

➕ What are Addition Facts?

Addition facts are like little number pairs with their answers that you can remember without counting every time. When you know these facts, it helps you add faster and makes your brain really good at mental maths.

🧠 How to Recognise and Remember Addition Facts

One way to remember addition facts up to 20 is to use patterns. For example, when you add zero to a number, the answer is the same number (like 5 + 0 = 5). Another pattern is when you add 10 to a number, the answer just goes up by ten (like 7 + 10 = 17).

📏 Using a Number Line

A great visual aid is a number line. You can start at one number on the line and then jump forward by the amount you are adding. For example, to solve 9 + 5, you start at 9 on the number line and make 5 jumps forward until you land on 14.

🧮 Mental Arithmetic Skills

Practising addition facts every day helps you do sums in your head. Instead of using fingers or objects to count, you learn to see the answer in your mind. For example, if you know 7 + 3 = 10, and someone asks you 7 + 4, you can quickly think, “7 + 3 is 10, so 7 + 4 must be 11.”

💡 Tips for Learning Addition Facts up to 20

  • Use flashcards with addition sums and answers to practise.
  • Try puzzles or games that ask you to add numbers to 20.
  • Say the addition sums out loud, like “10 plus 5 equals 15.”
  • Use everyday objects like toys or snacks to count and add.
  • Practice using a number line regularly to feel confident jumping along numbers.

Remember, learning addition facts up to 20 is fun and helps you become a super maths whiz! Keep practising little by little, and soon your addition skills will be fantastic. 🌟
