Cole is finding the quotient of 78 ÷ 4. He creates this model to help him solve the division problem. 3 10-cube rods and 4 groups of 1 10-cube rod plus 2 unit cubes.
Which statements are true about Cole’s work? Check all that apply.

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.
