Spelling numbers in words up to one million

Students match whole numbers with their number names and spell those names correctly.

• Choose the right name among three close versions, such as nine hundred or nine hundreds
• Spot errors in number names: plural thousands, tens instead of ten, fourty instead of forty
• Rewrite each wrong name in full, up to 999,000
• Use hyphens for numbers from twenty-one to ninety-nine

Reading and writing whole numbers with number names is standard 4.NBT.A.2.

Print all four pages: pages one and two are the practice, pages three and four the answer key. Keep the key aside.

• On page one, read each number aloud by groups of three digits before ticking a name.
• On page two, underline every wrong word first, then rewrite the whole name on the line.
• Watch for the trap: one name on page two is already correct.

The names use British style with and, like ten thousand and one; tell your child that US style drops it.

• Making place words plural: writing nine hundreds or ninety-five thousands; place words never take an s inside a number name.
• Mixing up forty and fourty: four keeps its u, but forty drops it.
• Forgetting the hyphen: fifty six instead of fifty-six, as in the first choice for 87,256.

Next, practice adding and subtracting whole numbers, then go back to place value with larger numbers.
