How many blocks were in the second stack? ** Jess’ second stack was 7 blocks + 5 blocks = <<7+5=12>>12 blocks.
How many blocks were in the third stack? ** Jess’ third stack was 12 blocks + 7 blocks = <<12+7=19>>19 blocks high.
How many blocks did Jess’ sister knock over? ** Jess’ sister knocked down the second tower and knocked 12 blocks – 2 = <<12-2=10>>10 blocks knocked over.
How many blocks did Jess’ sister knock over? ** Jess’ sister knocked down the final tower and knocked 19 blocks – 3 = <<19-3=16>>16 blocks knocked over.
How many blocks were in total knocked over? ** Total blocks knocked over was 7 blocks + 10 + 16 = <<7+10+16=33>>33 blocks.
