Develop confidence with number sequences from 100 by ones from any starting point

(ACMNA012)

 

• count forwards or backwards by ones, from a given three-digit number

• identify the numbers before and after a given three-digit number

    * describe the number before as 'one less than' and the number after as 'one more than' a given number (Communicating)

Investigate number sequences, initially those increasing and decreasing by twos, threes, fives and tens from any starting point, then moving to other sequences (ACMNA026)

 

• count forwards and backwards by twos, threes and fives from any starting point

• count forwards and backwards by tens, on and off the decade, with two- and three-digit numbers, eg 40, 30, 20, … (on the decade); 427, 437, 447, … (off the decade)
