I was a primary teacher in an inner city school that taught children who had 24 languages between them. My 5/6 year olds had a timetable the started at 8.50 every morning and continued (apart from two 10 minute breaks and 1 hour for lunch) until 3.15pm. Mornings were filled with Numeracy (this included number, data handling, shape and space, problem solving, measures, money and time) and Literacy. Afternoons were filled with Science, PE, RE, PHSCE, Music, ICT and Topic (which was basically History/Geography/Art/D&T and anything else it was decided we had to fit in). Children had to do 2 hours of Science, PE and RE every week. Friday afternoon was for free play and one to one reading. By the time you allowed for assemblies (provided they didn't over run) and assuming the children were where they should be every minute of the day (as opposed to the toilet, in the cloakroom, getting a drink etc) there was 23.75 teaching hours. If the mornings were taken up with Numeracy and Literacy then that left 10 hours 25 minutes for everything else. Of that time 6 hours was taken up by Science, RE and PE and 2 hours 15 was Friday afternoon. So that left 2 hours 10 mins for PSHCE, Music, ICT and Topic.
Do you see why I think the curriculum needs reducing not expanding?
If I had my way KS1 children would study number, money, time and money. Does a 5 year old need to be able to create and read a bar chart or be able to describe the properties of an ovoid? Literacy would cover reading (including reading for pleasure) and writing (including handwriting). Afternoons should be for PE, Art, RE, Music, ICT and play. PSHCE could be covered in circle time. There should be a story read to the whole class every day so that children can begin to enjoy books rather than seeing them as something to be dissected (This should continue throughout the school with the older children sharing a class book).
