  5. We can use our number lines to work out the sums which include negative numbers. What is -3 plus 5? -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 We start at -3

  6. We can use our number lines to work out the sums which include negative numbers. What is -3 plus 5? -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 =2 Next we count on 5 places to the right. We start at -3 After 5 jumps we arrive at 2

  7. Now try this one: What is -1 plus 3 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
