Christmas Rounding Rush
Save the snowmen from falling Christmas ornaments! Read the number on an ornament, round it to the requested place value, and tap the snowman showing the correct answer. Hurry — each ornament is heading for a snowman's head! Match pairs, earn points, and survive as long as you can.
Tap an ornament, then tap the snowman with its rounded value. Every correct pair pops away and a new pair appears. If an ornament hits a snowman, the game ends. Press Play Again to start a new game!
Choose a grade, then choose one rounding place value for the whole game. The Quick Guide and demo are shared.
Watch a Rounding Match!

Rounding Numbers
Grade 3 · Rounding to the Nearest 10 and 100
Grade 4 · Rounding Large Numbers
Round four-digit and five-digit numbers to the selected place value. Choose Nearest 10, 100, 1,000 or 10,000 before the game; the chosen rule stays the same throughout the game.
Round to the Nearest 10
Look at the ONES digit. If it is 0–4, round down; if it is 5–9, round up. Replace the ones digit with 0.
Round to the Nearest 100
Look at the TENS digit. If it is 0–4, round down; if it is 5–9, round up. Replace the last two digits with 00.
Round to the Nearest 1,000
Look at the HUNDREDS digit. If it is 0–4, round down; if it is 5–9, round up. Replace the last three digits with 000.
Round to the Nearest 10,000
Look at the THOUSANDS digit. If it is 0–4, round down; if it is 5–9, round up. Replace the last four digits with 0000. This mode uses five-digit numbers only.
Grade 5 · Rounding Decimals
Choose one decimal rounding challenge before the game. Read the digit immediately to the right of the place you are rounding to: 0–4 means round down, 5–9 means round up. The chosen place value stays the same throughout the game.
Round to the Nearest Whole Number
Look at the TENTHS digit (the first digit after the decimal point). Round the whole number down if it is 0–4, or up if it is 5–9. The answer has no decimal places.
Round to the Nearest Tenth
Look at the HUNDREDTHS digit (the second digit after the decimal point). Keep one decimal place, increasing the tenths digit when the hundredths digit is 5–9.
Round to the Nearest Hundredth
Look at the THOUSANDTHS digit (the third digit after the decimal point). Keep two decimal places, increasing the hundredths digit when the thousandths digit is 5–9.
