ACMNA012
Develop confidence with number sequences to and from 100 by ones from any starting point. Skip count by twos, fives and tens starting from zero
ACMNA013
Recognise, model, read, write and order numbers to at least 100. Locate these numbers on a number line
ACMNA014
Count collections to 100 by partitioning numbers using place value
ACMNA015
Represent and solve simple addition and subtraction problems using a range of strategies including counting on, partitioning and rearranging parts
ACMNA026
Investigate number sequences, initially those increasing and decreasing by twos, threes, fives and tens from any starting point, then moving to other sequences
ACMNA030
Solve simple addition and subtraction problems using a range of efficient mental and written strategies
