Students must be able to identify three-dimensional solids, including cylinders, cones, spheres, and cubes. Students should be able to identify three-dimensional solids by the number of faces, bases, vertices, edges, curved surfaces, etc. the solids may have. Students may also find the solids' abilities to roll, stack, or slide helpful in identifying the solids. Students should realize that the identity of the shape is not changed by its orientation, size, color, or texture. (K.6) B
Students must be able to identify the two-dimensional components or the flat surfaces of three-dimensional figures or solid figures. Students should know that two-dimensional figures are components of three-dimensional real-world objects. For example, a cone has the base of a circle. (K.6) C
Students must be able to classify and sort two-dimensional and three-dimensional figures based on attributes of the shapes and figures such as vertices, edges, etc. and realize that the identity of the shape is not changed by its orientation, size, color, or texture. K.6(E)

Students should be able to count to 20 and back from 20 with and without the use of objects. If students are using one-to-one correspondence where each object counted is matched accurately with a number word in correct sequence, students should be able to accurately recite the number they are counting. Students would gradually be able to recite the numbers to and from 20 without the use of objects. (K.2) A
Students must be able to name the number of objects in a set without counting but rather by instantly identifying the arrangement of objects. This instant recognition of a quantity is called subitizing. Everyday common objects such as the pips on dominoes or dice are helpful for students to understand this concept. Objects that come in groups of 2, 4, 5, and 10 are easiest for students to form a mental picture of first such as shoes, socks, fingers, toes, etc. (K.2) D
Students should be able to recite numbers as it relates to counting forward by ones and tens from any number between 1 and 100. (K.5) A
TEKS:
K.6(E)(R) Classify and sort a variety of regular and irregular two-dimensional and three-dimensional figures regardless of orientation or size. (Quarter 1 regular, two-dimensional shapes only)
K.6(B)(S) Identify three-dimensional solids, including cylinders, cones, spheres and cubes, in the real world.
K.6(C)(S) Identify two-dimensional components of three-dimensional objects
TEKS Embedded Throughout Unit
K.2(A)(S) Count forward and backward to at least 20 with and without objects
