'The array' is a tool that allows students to create arrays to learn their basic multiplication facts.
- Students are encouraged to develop mental strategies for multiplication by 'imagining' the use of 'the array'.
- The notion of commutativity is explored, for example, that 3 x 4 = 4 x 3.
An equation of up to 10 x 10 presented as an equation and in array format. Students work out the answer with the visual support of the array, then supply the answer twice more with progressively less visual support. Students are able to see the work they have done in table format using 'finished facts'. An introduction and tutorial is available. (The printout is currently not available - October 2007.)
The array: go figure
This is a tutorial designed for use by the student or as a demonstration tool for the teacher. The tutorial describes the different strategies that can be employed for solving multiplication calculations. It includes a number of multiplications questions for the student. It is amenable to a screen reader.
