How to Play
- Read the target number and the start and end of the line.
- Move the marker to the place where the number should live.
- Use the middle tick to ask: is the number below half, above half, or close to the end?
- Submit the estimate to reveal whether it is too far left, too far right, close, or exact.
- Finish all number lines to earn daily quest stars.
What It Teaches
The game trains magnitude sense, benchmark thinking, proportional distance, and flexible use of number lines. These are the ideas children need before decimals, fractions, negative numbers, and mental math feel natural.
A Good Question to Ask
Before your child submits, ask: Which landmark helped you choose that spot? A child who can explain 37 is a little before 50 on a 0 to 100 line is building real number sense.
