About Round It
The wavy equals sign here means "about", and your child picks the round number closest to the one shown, such as 50 for 47. Numbers never sit exactly halfway, so one answer is always closest. The oldest kids round three-digit numbers to tens or hundreds.
How to play
- Find the round numbers just below and just above the number.
- Decide which one it is closer to and tap it.
- On a keyboard, press 1 for the first answer, 2 for the second.
