Number Strategies resources

Students recommend which store offers the cheapest product based on calculations of percentage increase or decrease, and fully justify their answers.

Students identify fractions that are greater than a half, explain their reasoning, and identify how far from half some fractions are.

Students use rounding to estimate totals then discuss this as a method of estimation.

Task: calculate answer to questions about speed, distance, and time. Assessment focus: using a formula.

Students calculate percentage increases and decreases for odd jobs and show their working.

Students calculate the number of containers needed for given amounts of fruit for a recipe.

Students identify fractions that are greater than one, explain their reasoning and identify how far from one some fractions are.

Students find the number of groups of a given size using division, reverse multiplication, trial and improvement, or iterative equal sharing. Students must show their working.

Students work out fractional values of whole numbers in a range of contexts and show their working.

Students show how to divide given amounts into the number of groups of a given size.

Students show how they perform an addition and a subtraction problem, and write their own subtraction story problem.

Students explain why a range of students' answers to a maths problem are incorrect.

This task requires students to estimate some addition problems using any appropriate method.

This task requires students to estimate some addition problems using any appropriate method.

Students to show how they estimate in some addition problems.

Students estimate an addition problem, share their methods, discuss the averaging method, and then do more problems using averaging.

Students estimate a multiplication problem, share their methods, discuss the rounding method, and then do more estimation problems using rounding.

Students estimate a multiplication problem, share their methods, discuss the front-end method, and then do more problems using front-end.

Students estimate an addition problem, share their methods, discuss the front-end method and then do more problems using front-end.

In this task students decide which people are estimating and which are not, and explain their reasoning.

Students estimate an addition problem, share their methods, discuss grouping nice numbers, and then do a problem using this method, then design a question showing how it uses the method.

This practical task involves students making estimates of sets of items and demonstrating their method(s) of estimation.

In this practical task, students are to estimate the cost of meals ordered from a menu. The teacher reads out the meals and students show the steps in their estimations.

This practical task involves students making best estimates of sets of items and clearly demonstrating their method(s) of estimation.

Students estimate and explain how they estimated their answer for two number problems: one involving multiplication; and the other division.
