Multiplicative strategies

Learning intention

Students will develop their efficiency, flexibility and confidence in using a variety of mental strategies to solve problems of a multiplicative nature.

Syllabus outcome

• MAO-WM-01 develops understanding and fluency in mathematics through exploring and connecting mathematical concepts, choosing and applying mathematical techniques to solve problems, and communicating their thinking and reasoning coherently and clearly
• MA3-RN-01 applies an understanding of place value and the role of zero to represent the properties of numbers
• MA3-MR-01 selects and applies appropriate strategies to solve multiplication and division problems

Division

Students play the factors fun game to explore division, work out a solution and explain their thinking (one activity).

Students play the remainders game to reinforce division with remainders (two activities).

Students complete a multiplicative reasoning task with multiplicative thinking, based on the tiler problem solving task from reSolve (two activities).

Multiplication

Students play the youcubed math cards game to practice and consolidate their learning of multiplication and division (two activities).

Task 5: Prime climb hundreds chart

Students develop knowledge of factors, multiples and vocabulary associated with multiplication and division (one activity).

Task 6: Here is a problem

Students use close positioning scaffolds to consider the relationship between problems and not treat them as separate and unrelated (one activity).

Students recognise the different ways numbers can be presented in an array (two activities).

Students play in pairs to develop multiplicative automaticity (one activity).

Students reason with situations, instances and concepts that are always, sometimes or never true (one activity).
