Here is part of a number line. Write the missing numbers in the boxes.
The only number we’re given is the middle one, which is minus five or negative five. To find this number, we need to count forward seven from minus five. Minus four, minus three, minus two, minus one, zero, one, two. The number which is seven more than minus five is two.
We know the rule of the pattern is to count forward seven each time. To find this missing number, we’re going to need to work backwards and count back seven. Minus six, minus seven, minus eight, minus nine, minus 10, minus 11, minus 12. The number which is seven less than minus five is minus 12. The missing numbers are minus 12 and two.
