Unit 11- 2D Shapes
This unit bundles student expectations that address identifying two-dimensional shapes and their attributes, classifying and sorting two-dimensional shapes using formal and
informal language interchangeably, and creating two-dimensional shapes.
Prior to this unit, in Units 08 and 10, students learned the prerequisite skills of counting and sorting that are necessary for discerning attributes of two-dimensional shapes.
During this unit, students explore two-dimensional figures, including circles, triangles, rectangles, and squares as special rectangles. Students use their counting skills and
number relationships to determine the number of sides and vertices for each shape. Students use these attributes to discern different shapes from one another, whereas
orientation, color, texture, and size are not defining attributes of shapes. Informal and formal language is used interchangeably as students identify the attributes of two-dimensional shapes. Students examine the attributes and properties of two-dimensional figures to distinguish between regular or irregular figures. Students apply their
knowledge from data analysis to sort and classify two-dimensional figures. Students also develop spatial reasoning and visualization skills to create circles, triangles, rectangles, and squares using a variety of materials and drawings.
After this unit, in Unit 12, students will identify three-dimensional figures and identify two-dimensional shapes as parts of three-dimensional figures.
Make sure that your are not teaching a square as a separate shape it is a special rectangle that has sides that are the same length.
Just a Couple of Ideas
Love this idea for math Journals!
Great Anchor Chart!
I like this anchor chart, only adjustment I would make is to put a square underneath rectangle and put that it is a special rectangle.
Love the idea of giving them a shape and having them turn it into something.
