### Number and Algebra

Big steps in growing
AC content descriptors: ACMNA012, ACMNA018
Students will skip count in tens, identify the numbers in the counting pattern and use skip counting by tens to count a collection. They will develop confidence with number sequences to and from 100 by ones from any starting point. Students will skip count by twos, fives and tens starting from zero.

The teen game
AC content descriptors: ACMNA013, ACMNA014
Students will use standard place-value partitioning to represent ‘teen’ numbers. They will recognise, model, read, write and order numbers to at least 100 and locate these numbers on a number line.

When I’m a teenager
AC content descriptors: ACMNA013, ACMNA014
Students will identify, represent and order ‘teen’ numbers. They will recognise, model, read, write and order numbers to at least 100 and locate these numbers on a number line.

Put them together
AC content descriptor: ACMNA015
Students will rearrange the parts of an addition situation to show the commutative principle, using appropriate thinking strategies to solve simple addition problems. They will record addition problems with numerals and symbols.

Pattern pursuit
AC content descriptor: ACMNA018
Students will identify, describe and create repeating patterns by investigating and describing number patterns formed by skip counting and patterns with objects.

### Measurement and Geometry

Dare to compare
AC content descriptor: ACMMG019
Students will identify and explore the attribute of length by measuring and comparing the lengths and capacities of pairs of objects using uniform informal units.

My special time
AC content descriptor: ACMMG020
Students will tell time to the hour and half-hour and match analog and digital time representations.

### Statistics and Probability

What’s the chance?
AC content descriptor: ACMSP024
Students will explore and describe the likelihood of an event occurring using the chance terms ‘possible’ and ‘impossible’. They will identify outcomes of familiar events involving chance and describe them using everyday language such as ‘will happen’, ‘won’t happen’ or ‘might happen’.
