Find the size of each jump first: count the jumps between two numbers you know. Then count on from the nearest labelled number: halfway from 4,000 to 5,000 is 4,500.
number linenumbers in order, evenly spaced along a line
ticka small mark for a number on the line
betweenafter one number and before the next
closer tofewer steps away
Watch for: Counting the ticks instead of the jumps between them. Assuming each jump is 1 when the line counts by more. Ordering by the first digit only when the numbers have different lengths.
At home: Draw a line from 0 to a big round number on paper, and take turns marking where a number goes. Check by counting the jumps.
