Detailed Explanation of Converting Between Digits and Words up to 1,000 ๐Ÿ”ขโœ๏ธ

Step 1: Understanding Digits and Words ๐Ÿ“š

  • Digits are the numbers we see and write, like 7, 25, or 512.
  • Words are how we say or write these numbers using letters, like “seven,” “twenty-five,” or “five hundred and twelve.”

Step 2: Reading Numbers in Words ๐Ÿ‘‚๐Ÿ“–

When reading numbers up to 1,000, follow this order:

  1. Hundreds place (if there is one): How many hundreds? For example, in 347, the digit 3 is in the hundreds place, so it is “three hundred.”
  2. Tens and ones place: Look at the last two digits. For example, 47 is “forty-seven.”
  3. Put it together: “Three hundred and forty-seven.”

Examples:

  • 125 = “one hundred and twenty-five
  • 500 = “five hundred
  • 999 = “nine hundred and ninety-nine

Step 3: Writing Numbers in Digits โœ๏ธ๐Ÿ”ข

When you hear or see a number in words, like “six hundred and twenty,” break it down:

  1. Hundreds: “six hundred” means 6 in the hundreds place โ†’ 600
  2. Tens and ones: “twenty” means 2 tens โ†’ 20
  3. Add them together: 600 + 20 = 620

Examples:

  • two hundred and seventeen” โ†’ 217
  • eight hundred and four” โ†’ 804
  • one hundred” โ†’ 100

Step 4: Special Tips ๐Ÿ’ก

  • Remember the word “and” usually comes between the hundreds and the tens/ones part (like “one hundred and twenty“).
  • If there are no tens or ones digits, you just say the hundreds (like “four hundred,” which is 400).
  • Numbers below 20 have special names, like “eleven,” “twelve,” or “fifteen.” Make sure to learn these as they donโ€™t follow the usual pattern.

Why This is Important ๐ŸŽฏ

In the Key Stage 2 Curriculum, being able to switch between digits and words up to 1,000 helps you understand place value, number structure, and improves your reading and writing of numbers. This skill is used in many topics like addition, subtraction, and problem solving.

Practice Example ๐Ÿ“

Write the number 286 in words:

  • 2 hundreds = “two hundred
  • 86 = “eighty-six
  • Answer: “two hundred and eighty-six

Write in digits the number “nine hundred and seventy“:

  • 9 hundreds = 900
  • 70 = 70
  • Answer: 970

Keep practising with different numbers by saying them out loud, writing them in digits, and spelling them out in words! ๐Ÿ“ฃโœ๏ธ
