Multiplicative thinking resources

Students answer a question about working out many kilometres were travelled in one hour from a given time to travel one kilometre.

Students calculate the number of packets of biscuits that need to be sold, and how many house visits are needed to attain a given profit.

Students calculate the percentage by which clothing prices have been reduced.

Students calculate percentages of whole numbers and convert fractions to percentages.

Students solve linear equations based on pizza orders and cooking times.

Students solve number problems involving prices which include and exclude GST.

Students show how they estimate in some multiplication problems and come up with sensible estimates.

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

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

Students answer four multiple choice questions identifying which three-digit number can be divided by a one-digit number to get a given remainder.

Students select which four-digit numbers can be divided by a one-digit number without a remainder.

Students calculate the cost of a set of books given unit prices for an individual book.

Students identify numbers using clues which give the range within which each number falls and two factors with their remainder.

Students answer questions about the difference between a range of given times in minutes.

Students explain multiplication estimation methods used to solve word problems.

Students interpret a pie graph to answer multiple choice questions.

Students identify different ways that given amounts of money can be made up using a range of coins and notes.

Students multiply two numbers, then divide the total by 3 and by 6.

Students show how they solve equal sharing problems.

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

Students calculate the area of composite shapes.

Students halve and double a range of numbers.

Students estimate a division problem, share their methods, discuss the nice numbers and factors method, and then do more problems using nice numbers and factors.

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

Students discuss making an interval estimate in multiplication problems (i.e., getting a lower and an upper limit for the actual answer using the front-end and rounding-up estimation methods). They then use this method on two problems.
