Addition in Year 3 and 4
The most important aspect of addition that children need to understand is that sometimes addition can be done mentally and sometimes this isn't possible so you need to use a formal jotting to help organise their thinking.
Which of these number sentences might you do mentally and which would you need a written method for?
43 + 44 = 65 + 65 = 321 + 100 =
423 + 103 = 8 + 9 + 5 = 1237 + 5439 =
6565 + 5656 = 7777 + 8888 = £23.65 + £2. 23 =
