(3x7) + (3x9) NBT.6 2 b. 16 bags 4.NBT.5 3 (394x7) x 2 = 5,516 pages; 394 x7 = x2 = 5,516 or = 5,516 pages Set 6 Standard Question Answer 5.NBT.6 1 c = 13r6 5.MD.3 2 c. twenty-seven cubic inches 4.NBT.2 3 Short Answer: a. 19,009 _< 19,090 b. 968,305 = 968,305 c. 72,066 _< 72,660 Look for an explanation explaining the value of the places. Set 7 Standard Question Answer 5.MD.3 1 b. one cubic inch 5.MD.4 2 a. 48 cubic inches 5.OA.1 3 Short Answer: Kevin is correct: Amanda started with 60 divided by 5 and she should have started with the

33 parentheses because of the order of operations. Kevin started correctly but should have done 60 divided by 5 which = 12 and then 12 x 6 = 72 because of order of operations with multiplication and division you work left to right. Set 8 Standard Question Answer 5.MD.4 1 c. 20 cubic centimeters 5.MD.5 2 d. (6x2) NBT.6 3 Short Answer: He would have 4 cards on his last page. 2,188 divided by 14 = 156 R. 4 That means that there are 156 full pages of 14 cards and on the 157 th page there is only 4 cards.

Parallelogram 3.) Square A correct explanation may include that

34 all Quadrilaterals have 4 sides so all the shapes listed would fall under quadrilateral. A parallelogram is any quadrilateral with two sets of parallel sides and all the other shapes fall under parallelogram. A square would be last because it is a specific parallelogram that is a rectangle with equal sides and equal angles.
