📚 Starter Activity for Your Maths Lessons Looking for a quick problem-solving task to get students thinking from the very start of the lesson? 🧠 Challenge your students to find the SUM of 1 + 2 + 3 +...+ 100 🚫 No calculator 💬 Encourage discussion 🔍 Focus on patterns and reasoning rather than lengthy calculations This task works brilliantly for: ✔ KS3 ✔ GCSE ✔ Stretch & challenge ✔ Mathematical reasoning starters Possible discussion points: - Is there a faster method? - Can students justify their strategy? - Can they find more than one approach? - How can they communicate their reasoning clearly? These are the types of tasks I use regularly to build confidence, problem-solving, and deeper mathematical thinking in the classroom. Let me know how your students approached it 👇

🧠 Welcome to my first challenge post! Can you solve the famous Seven Bridges of Königsberg problem? 🌉 The challenge:👉 Can you cross each bridge EXACTLY ONCE and return to where you started? Think carefully before answering: - Is it possible? - If not, why not? - Can you explain your reasoning logically? This is a brilliant problem for developing:✔ logical thinking✔ reasoning skills✔ problem solving✔ mathematical communication I use challenges like this to encourage students to THINK deeply from the very start of lessons.
