Eddy’s spider plant produces 2 baby plants 2 times a year.  After 4 years, how many baby plants will the mother plant have produced?
The mother plant produces 2 baby plants 2 times a year so it produces 2*2 = <<2*2=4>>4 plants a year
It produces 4 plants a year so after 4 years it will produce 4*4 = <<4*4=16>>16 baby plants
