Discuss in grade what happens when we take several groups of 10.
Note for Teachers: Support the learners in understanding multiplication when group 
size is a multiple of 10. Language of ‘tens’ is a useful way to think about this.
For example: 16 × 10  = 16 Tens  is 160
 16 × 20  = 16 × 2 Tens = 32 Tens = 320
