Task outline

Full task descriptions are included in the resource, available for download on this page.

Division

Task 1: Factors fun

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

Task 2: Remainders game

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

Task 3: The tiler

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

Multiplication

Task 4: youcubed math cards

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).

Task 7: Array bingo

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

Task 8: Multiplication toss

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

Task 9: Always, sometimes, never

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

Task 10: Multiplication squares

Students use their knowledge of factors and products to find the missing element in a grid (three activities).
