Multiplication resources

This task requires students to show how to estimate numbers of items in some multiplication problems using any acceptable estimation strategy.

Students answer maths problems involving multiplication, and show their working.

Students show how to work out the number of 1-digit that there are in 2-digit numbers.

Students explain multiplication estimation methods used to solve word problems.

Students use doubling and halving to solve multiplication problems.

Students perform decimal multiplication and division involving the cost of material, without the use of a calculator.

Students display their knowledge of algorithms by filling in missing digits for some computations.

Students complete 3 multiplication arrays by selecting from given numbers.

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

Students write number sentences for story problems, and create story problems from number sentences.

Students complete linear equations for given word problems involving multiplication.

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.

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

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