Numbers up to 10,000

Big numbers around us

Numbers up to 10,000 count things such as pupils in a county school, shillings in a savings group or kilometres between towns. The KICD Grade 4 curriculum builds on numbers to 1,000 learned earlier.

Place value

Each digit has a place and a value. In 3,752:

So 3,752 = 3,000 + 700 + 50 + 2. This is called expanded form.

Reading and writing

• 3,752 = three thousand, seven hundred and fifty-two
• 6,009 = six thousand and nine
• 10,000 = ten thousand

Comparing numbers

1. Count the digits; more digits means a bigger number.
2. If the digits are equal, compare from the left.
3. Use > (greater than), < (less than) or = (equal to).

Example: 4,586 > 4,568 because 8 tens is more than 6 tens.

Ordering

Ascending means smallest to biggest: 1,205; 1,250; 2,105. Descending means biggest to smallest: 2,105; 1,250; 1,205.

Rounding

Round to the nearest ten: 3,752 becomes 3,750. Round to the nearest hundred: 3,752 becomes 3,800.

Try it

• Write 5,408 in words and in expanded form.
• Put in ascending order: 7,090; 7,009; 7,900.
• Round 6,847 to the nearest hundred.
