Two new cameos this month.
The Task Cameo Content Finder has been updated to include these tasks.

• Surface Area with Tricubes explores the meanings of area, surface area and volume while at the same time exploring the spatial skill of representing 3D objects using isometric paper. The basic shape is one Tricube. Its volume is constant at three unit cubes. Its surface area is constant at 14 unit squares. But its base area will depend on how it is placed on the table. One possibility produces a remarkable base area of zero.
• Growing Tricubes focuses on pattern and algebra. The key is discovering that 'four Tricubes make a Tricube', which actually isn't true. Understanding why powers a Sphinx-like investigation in three dimensions which produces a visual pattern that can also be represented as various number patterns and this leads to algebra and functions, graphing, equation work and scale factors.
