1.GEO Geometry and spatial reasoning.

1.111.13.1.6 The student uses attributes to identify two- and three-dimensional geometric figures. The student compares and contrasts two- and three-dimensional geometric figures or both.
1.111.13.1.6.A describe and identify two-dimensional geometric figures, including circles, triangles, rectangles, and squares (a special type of rectangle);
1.111.13.1.6.B describe and identify three-dimensional geometric figures, including spheres, rectangular prisms (including cubes), cylinders, and cones;
1.111.13.1.6.C describe and identify two- and three-dimensional geometric figures in order to sort them according to a given attribute using informal and formal language; and
- Geometry: Same shape (First grade - J.12)
1.111.13.1.6.D use concrete models to combine two-dimensional geometric figures to make new geometric figures.

1.MEA Measurement.

1.111.13.1.7 The student directly compares the attributes of length, area, weight/mass, capacity, and temperature. The student uses comparative language to solve problems and answer questions. The student selects and uses nonstandard units to describe length.
1.111.13.1.7.A estimate and measure length using nonstandard units such as paper clips or sides of color tiles;
1.111.13.1.7.B compare and order two or more concrete objects according to length (from longest to shortest);
- Measurement: Long and short (Kindergarten - Q.1)
- Measurement: Tall and short (Kindergarten - Q.2)
1.111.13.1.7.C describe the relationship between the size of the unit and the number of units needed to measure the length of an object;
