Number and Algebra resources

Students use doubling and halving to solve multiplication problems.

Students place decimal numbers in the correct order and position on a number line.

Students calculate the weight of parts of a fish from given proportions.

Students calculate the repair charges for two different washing machine repair companies, and compare and explain their results.

Students calculate the repair charges of two different garages, graph them, and explain the results.

Students select the correct simplifications for algebraic expressions.

Students use substitution into equations to evaluate the number of blocks and total surface areas in shapes of different heights. The stimulus can be used as a challenging task to try and derive the rules from the spatial pattern. This is classified as Patterns and Relationships.

Students interpret and graph linear equations of monthly charges for Internet access.

Students select the correct factorisation of algebraic expressions.

Students factorise algebraic expressions.

This task is about working out change for a variety of purchases.

Students calculate how price changes affect a purchase.

Students interpret a table about the amount of money raised for a run-a-thon, and graph the points represented.

Students solve given algebraic expressions using substitution.

Students solve a number of mathematical problems for practical situations involving total amounts, age and time.

Students solve algebraic problems about people's ages using information given.

Students use given information to solve a story problem about paper deliveries and identify the correct algebraic equation for the answer. They also write an algebraic equation for a similar story problem.

Students identify odd and even numbers from a series of numbers and from a word problem. They then explain how to identify an odd number.

Students demonstrate their understanding of place value by identifying numbers shown in a shape-based number system.

Students select from a set of numbers to show the closest number to each population fact.

Using information about the shape-based number system on planet Efilar, students display the base 10 numbers for Efilar shapes. Students also display Efilar shapes from given base 10 numbers.

Students state temperatures to the nearest tenth degree, between two given temperatures. They also order a set of temperatures from coldest to warmest.

Students put four or five-digit numbers into the correct range of values in which that number lies.

Students explore multiples of 2, 10, and 20 using repeated addition on a given starting number.

Students write amounts shown on a grid as percentages or decimal fractions.
