Think about the Base Ten blocks you used during the lesson. Using 1 hundred block, 3 ten blocks, and 6 one blocks, create a shape with the largest possible perimeter. Remember that the blocks need to be touching along a side, not connected at a corner. Sketch your solution and show all of your work. 2-48 HW eTool (CPM). Homework Help ✎

A reminder: The perimeter is the sum of the lengths of a shape's sides. Be sure to make the longer sides of the blocks exposed to increase the perimeter.

The blocks should be in a long line for the perimeter to be its greatest. The perimeter is 112.

Use the blocks in the eTool below and try to arrange them in a shape with the largest perimeter.
