A Typical Maths Lesson Mental Warm Up : 10 minutes E.g.: Bingo, game, counting stick, interactive activity Main Teaching : 20 minutes Activities and challenge : 20 – 25 minutes Plenary : 5-10 minutes
A Typical Mental Warm Up... Bingo!
Teaching Calculation - Remembering number facts Lies at the heart of numeracy Mental method is emphasised - Remembering number facts - Using them to work out new facts - Understanding the relationship between ‘the 4 rules’ - Repertoire of mental strategies. Written methods follow on Application to real life e.g.: problem solving

Know and use number bonds to 10 and 20 Addition Know and use number bonds to 10 and 20 2 + 8 = 10 20 + 80 = 100 200 + 800 = 1000 22 + 8 = 30 Use a number line to count, putting the biggest number first
Addition 15 + 13 = Add to the next 10 and then add the extra Add 2 numbers that bridge 10 Add to the next 10 and then add the extra Adding 2 2-digit numbers (without bridging) 15 + 13 = + 10 + 3
