Supplied materials

  • Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
  • Supplied worked-case record: Starting at 97, four steps are 98, 99, 100, 101.
  • All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

After ninety-nine, the count reaches one hundred. Number names and written numerals keep the same one-more pattern. A three-digit numeral is needed at one hundred, but counting does not start over. Continue using complete numeral labels for each step.

Write the supplied starting numeral. Add one for each new step and record the sequence, paying attention when ninety-nine becomes one hundred. Check by counting aloud with an adult if a numeral is unfamiliar.

Use a new box for each counting step. Counting does not restart at one after ninety-nine. Write a short consecutive number strip, including 99,100,101 where relevant.

  1. Write a short consecutive number strip, including 99,100,101 where relevant.
  2. Follow the worked example. Point to each number or shape feature and say what it tells you.
  3. Write the supplied starting numeral.
  4. Try the question and then the three practice questions. Check your answers and explain any change you make.
Worked example

See the method in action

Starting at 97, four steps are 98, 99, 100, 101. The last number is 101. Ninety-nine plus one completes one hundred, and the next object gives one hundred one. The starting position is not included among the four new steps. Use a new box for each counting step. Counting does not restart at one after ninety-nine. Write a short consecutive number strip, including 99,100,101 where relevant.
