These new numbers are negative numbers.



We can use our number lines to work out the sums which include negative numbers.



First we locate -3 on the number line.



We start at -3



We can use our number lines to work out the sums which include negative numbers.



We start at -3



We can use our number lines to work out the sums which include negative numbers.



Next we count on 5 places to the right. We start at -3 After 5 jumps we arrive at 2
