Place Value
If Sally uses crates to pack
1,000 blocks, boxes to pack 100 and stacks to pack 10, how many packages could she have used if she had 3,240 blocks in all.
3 crates, 24 boxes = (3 x 1,000) + (24 x 100) = 5,400
32 crates, 4 boxes = (32 x 1,000) + (4 x 100) = 32,400
32 boxes, 4 stacks = (32 x 100) + 4 x 10) = 3,240
3 crates, 2 boxes, 40 stacks = (3 x 1,000) + (2 x 100) + 40 x 10) = 3,600
