Numbers to 100 000
In Grade 5 we work with numbers up to 100 000. These numbers have five digits and use place value: ten-thousands, thousands, hundreds, tens and ones. Understanding place value helps us read, write and order large numbers.
Example
Place Value Breakdown
The number 64 827:
• 6 ten-thousands = 60 000
• 4 thousands = 4 000
• 8 hundreds = 800
• 2 tens = 20
• 7 ones = 7
Expanded: 60 000 + 4 000 + 800 + 20 + 7 = 64 827
Example
Ordering Large Numbers
Order from smallest to largest: 45 230, 54 320, 43 520
Compare ten-thousands: 4, 5, 4
Two have 4 ten-thousands — compare thousands: 5 > 3
Answer: 43 520, 45 230, 54 320
Note
Remember
When comparing numbers, always start from the left-most digit. The number with the greater digit in the highest place value is the larger number.
