Cole is finding the quotient of 78 + 4. He creates this model
to help him solve the division problem
Which statements are true about Cole's work? Check all
that apply
D
Cole's model correctly shows that the quotient of 78 + 4
is 12 with a remainder of 30.
Cole has not finished modeling this problem
Cole needs to add another ten block to his model to
show 78
Cole should have divided the 3 extra tens blocks into 30
ones blocks
A complete model would show the quotient of 78 -4 is
19 with a remainder of 2
