I have an interview coming up and I am planning my lesson (25mins with y2/3). My idea is to work out prices of items by adding up their letters e.g. bag = 1 + 2 + 7 = 10p for bag. I am confident this meet y2 objectives: two-digit number and 1s a two-digit number and 10s 2 two-digit numbers adding 3 one-digit numbers For the y3s I would challenge them to find the most expensive item therefore they will be adding numerous numbers. However I cant find in the new curriculum where children add more than two numbers the curriculum objectives for y3 states: add and subtract numbers with up to 3 digits, using formal written methods of columnar addition Obviously these numbers are not 3 digits but they will be adding 3-10 numbers up. What are your views on this? Is it challenging enough? Does this meet an objective or do I need to start again! Also If teaching high ability year 3s can I look at y4 objectives or is this now a big no no!? - I am currently on maternity leave and having a crash of confidence in myself! Thank you in advance for any help given.
