Money is a great way to encourage children with their addition and subtraction and of course, it is the spending of it when we most use our mental arithmetic skills!
This worksheet is for Year 1 children who are confident with counting and adding small numbers. It uses three coins, the 1p, 5p and 10p. Encourage trying to add in order of size, starting with the largest coin and, if necessary, counting on from that.
This is very good source to teach kids about money calculation, , I am intrested to see more of this excercise
