Next they will take the single blocks that they used to measure the item and pack the blocks as much as possible. To pack as much as possible, there can be no more than 9 blocks of any size. If there are ten blocks of a size, then they can be packed into a larger holder to form a larger block. They continue by measuring and estimating the next item on their list. Activity Students estimate and then measure each item, recording the number of single blocks used.
Students pack the blocks used to measure each item.
The blocks should be packed as much as possible. The number of each size block should be recorded on their activity sheets . Students should be encouraged to reflect on the number of single blocks versus the number of packed blocks. Closure Ask students to compare their measurements. If any students measured the same item, see if they reached the same number of blocks for that item.
