Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Write this number using digits: eight hundred eighty-five thousand seven hundred eleven.
answer box
Show answer
885711
Hint: Split the number at the word “thousand”. Write the thousands part, then the last three digits. Use a 0 to hold any empty place.
Question 2
What number is 10 000 more than 294 357?
answer box
Show answer
304357
Hint: Only the ten thousands digit should change by 1. If that digit is 9, regroup with the place to its left.
Question 3
What number is 200 000 + 10 000 + 9000 + 300 + 70?
answer box
Show answer
219370
Hint: Each part fills one place value. Write the digits from the greatest place to the ones, and put a 0 in any place that is missing.
Question 4
In 497 356, what is the value of the digit 9?
- 90 000
- 900 000
- 900
- 9000
Show answer
90 000
Hint: Name the place of the 9, counting from the right: ones, tens, hundreds, thousands, ten thousands, hundred thousands. The digit is worth 9 of that place.
Question 5
Which number is closest to 750 000?
- 745 300
- 74 530
- 710 600
- 780 200
Show answer
745 300
Hint: Find how far each number is from the benchmark. Check the number of digits too: a number with fewer digits is much smaller.
Question 6
Round 205 159 to the nearest ten thousand.
- 210 000
- 200 000
- 205 000
- 190 000
Show answer
210 000
Hint: Look at the digit just to the right of the ten thousands place. If it is 5 or more, round up; if it is less than 5, round down. Then every place to the right becomes 0.
