Gate Number Line

Along a quiet rail, chalk marks sat like a number line: 0 toward the shed, 10 toward the creek.
Start at 3, said Spike. Hop plus 4. Where do you land?
Suzy walked: 3, then 4, 5, 6, 7. Land on 7. Not 8 because hope hopped extra.
Now minus 2 from 7. Back to 5. The line told the truth either direction.
Canberra approved of orderly numbers. Harare tested whether 5 was a good waiting spot.
Explorer gear feeling helped Suzy see the marks — looking, not magic sight.
If you start at 9 and add 2, you leave the tidy 0–10 line — that is a clue to expand or stop.
Little Thunder parked at 0 like a mahogany origin story.
Kids: chalk a number line on the driveway. Practise + and − with feet.
Number lines make farm jumps visible: forward care, back check.
Thinking Cap reminds: know your start before you hop.
Start. Hop. Land true.
