reSolve: Multiplication – making robots

This sequence of lessons introduces the key idea of multiplication as a Cartesian product, using the language of 'for each'. Students explore the total number of different robots that can be made using three heads, three bodies and three feet. The students represent the different combinations for the robots as array. The sequence is outlined in detail including curriculum links, vocabulary, materials needed, discussion points and student resources such as templates and card sets. This sequence is part of the reSolve: Mathematics by Inquiry program.
