The original questions are in Japanese. 十の位 means “tens”, 百の位 means “hundreds”, 千の位 means “thousands”. 上から1けた means “one significant digit”; 上から2けた means “two significant digits”.
For families and teachers
Find the place to keep, then inspect the digit immediately to its right. Compare the rounded answer with the original number on a number line.
This English guide uses the original Chicodori Scratch project. Some labels remain in Japanese. You can explore and remix the project on Scratch.
