I have an 20 min interview lesson next week (Thurs). I have to teach a group of 25 year 1/2s a maths lesson. No other info than that! Would really appreciate constructive comments........ Should I do a 1, 2 min mental maths warm up? For my 'actual' lesson I was going to a lesson which is linked to the NNS objectives of: 1) Make and describe models and patterns. 2) Use one or more shapes to make, describe and continue repeating patterns. I will present the children with a multilink model of 5 blocks, in a ?H? shape. Ask the children if they can work out how to make the model exactly twice as big. Questions to ask ?How many cubes would you need if you were going to make it 2, 3, 100 times bigger?? ?How do you know?? ?How could you check?? Children to record their predictions or findings on squared paper. Plenary would be sharing how the children predicted the number of cubes.
