### Number and Algebra

Hundreds and thousands
AC content descriptors: ACMNA052, ACMNA053
Students will compare three-digit numbers, describing them as ‘bigger than’ and ‘smaller than’ and order a series of three-digit numbers on an empty number line, showing relative position. They will recognise, model, represent and order numbers to at least 10 000 and apply place value to partition, rearrange and regroup numbers to at least 10 000 to assist calculations and solve problems.

School Challenge
AC content descriptors: ACMNA052, ACMNA053
Students will represent four-digit numbers to 2000 with materials and read, write and compare three-digit and four-digit numbers. They will recognise, model, represent and order numbers to at least 10 000 and apply place value to partition, rearrange and regroup numbers to at least 10 000 to assist calculations and solve problems.

Flying high
AC content descriptors: ACMNA052, ACMNA053
Students will partition four-digit numbers into place-value parts. They will recognise, model, represent and order numbers to at least 10 000 and apply place value to partition, rearrange and regroup numbers to at least 10 000 to assist calculations and solve problems.

Wholes and parts
AC content descriptor: ACMNA058
Students will describe fractions as equal-sized parts of a whole and represent halves, fourths and eighths of a whole shape or object. They will model and represent unit fractions including half, quarter, third, fifth and their multiples to a complete whole.

Cutting it up
AC content descriptor: ACMNA058
Students will represent fractions using linear materials and recognise key equivalent fractions and share collections equally to solve simple problems (halves, quarters and eighths). They will model and represent unit fractions including half, quarter, third, fifth, eighth and their multiples to a complete whole.

### Measurement and Geometry

Fill it up
AC content descriptor: ACMMG061
Students will establish a mental image of one litre and measure the capacity of familiar everyday containers using litres. They will measure, order and compare objects using standard metric units of length, mass and capacity.

Angle it
AC content descriptor: ACMMG064
Students will describe angles as the amount of turn between two lines and locate angles in the real world. They will identify angles as measures of turn and compare angle sizes in everyday situations.

### Statistics and Probability

Come in spinner
AC content descriptor: ACMSP067
Students will recognise and describe variations in results and conduct a simple experiment with spinners. They will conduct chance experiments, identify and describe possible outcomes and recognise variation in results.

Lucky dip
AC content descriptors: ACMSP067, ACMSP069
Students will describe everyday chance events and conduct chance experiments. They will collect, organise, and display data and interpret and compare data displays.
