We have started a new unit in math called Geometry.  The students will be learning about 2D and 3D shapes.  The learning goals for the unit from the Math Makes Sense resource are: Compare and sort objects or shapes according to one attribute, such as number of sides or whether they have curves. Describe objects and shapes.  For example, some objects can roll, some have points, some are curved, and some can stack. Reproduce composite objects and shapes, such as towers. Identify shapes on objects, such as a circle on the bottom of a yogurt container.
