    Tap the numbers from smallest to biggest.

    • 930
    • 893
    • 984
    • 841
    Show answer

    841 → 893 → 930 → 984

    Hint: Compare the hundreds first, then the tens, then the ones. The smallest is 841.

    Tap the numbers from smallest to biggest.

    • 540
    • 437
    • 228
    • 276
    Show answer

    228 → 276 → 437 → 540

  3. Question 3

    There were 430 people at a concert. 323 people left early. How many people stayed?

    🎵
    • 117
    • 113
    • 753
    • 107
    Show answer

    107

    Hint: Take away to find what's left: 430 − 323. Count up from 323 to 430: +7, +70, +30. Add the jumps: 7 + 70 + 30 = 107.

  4. Question 4
