K.G.1 - Describe objects in the environment using names of shapes, and
describe the relative positions of these objects using terms such
as above, below, beside, in front of, behind, and next to.
K.G.2 - Correctly name shapes regardless of their orientations or overall
size (squares, circles, triangles, rectangles, hexagons, cubes,
cones, cylinders, and spheres).
K.G.3 - Identify shapes as two-dimensional (lying in a plane, “flat”) or
three-dimensional (“solid”) (squares, circles, triangles, rectangles,
hexagons, cubes, cones, cylinders, and spheres).
2.G.1 - Recognize and draw shapes having specified attributes, such as
a given number of angles or a given number of equal faces.5
Identify triangles, quadrilaterals, pentagons, hexagons, and
cubes.
3.G.1 - Understand that shapes in different categories (e.g., rhombuses,
rectangles, and others) may share attributes (e.g., having four
sides), and that the shared attributes can define a larger category
(e.g., quadrilaterals). Recognize rhombuses, rectangles, and
squares as examples of quadrilaterals, and draw examples of
quadrilaterals that do not belong to any of these subcategories.
4.G.2 - Classify two-dimensional figures based on the presence or
absence of parallel or perpendicular lines, or the presence or
absence of angles of a specified size. Recognize right triangles
as a category, and identify right triangles.
5.G.3 - Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that
category. For example, all rectangles have four right angles and
squares are rectangles, so all squares have four right angles.
5.G.4 - Classify two-dimensional figures in a hierarchy based on
properties.
K.G.5 - Model shapes in the world by building shapes from components
(e.g., sticks and clay balls) and drawing shapes.

“Can you join these two triangles with full sides touching to make
a rectangle?”
1.G.1 - Distinguish between defining attributes (e.g., triangles are closed
and three-sided) versus non-defining attributes (e.g., color,
orientation, overall size); build and draw shapes to possess
defining attributes.
1.G.2 - Compose two-dimensional shapes (rectangles, squares,
trapezoids, triangles, half-circles, and quarter-circles) or threedimensional shapes (cubes, right rectangular prisms, right
circular cones, and right circular cylinders) to create a composite
shape, and compose new shapes from the composite shape.4
2.G.1 - Recognize and draw shapes having specified attributes, such as
a given number of angles or a given number of equal faces.5
Identify triangles, quadrilaterals, pentagons, hexagons, and
cubes.

constraint or condition in a real-world or mathematical problem.
Recognize that inequalities of the form x > c or x < c have
infinitely many solutions; represent solutions of such inequalities
on number line diagrams.
7.EE.4 - Use variables to represent quantities in a real-world or
mathematical problem, and construct simple equations and
inequalities to solve problems by reasoning about the quantities.
b. Solve word problems leading to inequalities of the form px
+ q > r or px + q < r, where p, q, and r are specific
rational numbers. Graph the solution set of the inequality
and interpret it in the context of the problem. For example:
As a salesperson, you are paid $50 per week plus $3 per
sale. This week you want your pay to be at least $100.
Write an inequality for the number of sales you need to
make, and describe the solutions.
8.G.13 - Determine the slope of a line from a
graph and explain the meaning of
slope as a constant rate of change
8.EE.6 - Use similar triangles to explain why the slope m is the same
between any two distinct points on a non-vertical line in the
coordinate plane; derive the equation y = mx for a line through

8.EE.8 - Analyze and solve pairs of simultaneous linear equations.
8.G.15 - Graph a line using a table of values

8.G.16 - Determine the equation of a line
equations in two variables correspond to points of

b. Solve systems of two linear equations in two variables
8.G.18 - Solve systems of equations
algebraically, and estimate solutions by graphing the
graphically (only linear, integral
equations. Solve simple cases by inspection. For example,
solutions, y = mx + b format, no
3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x +

2y cannot simultaneously be 5 and 6.
8.G.20 - Distinguish between linear and
c. Solve real-world and mathematical problems leading to two
nonlinear equations ax2 + bx + c; a=1
linear equations in two variables. For example, given
(only graphically)
coordinates for two pairs of points, determine whether the
line through the first pair of points intersects the line
through the second pair.
8.F.3 - Interpret the equation y = mx + b as defining a linear function,
whose graph is a straight line; give examples of functions that
are not linear. For example, the function A = s2 giving the area of
a square as a function of its side length is not linear because its
graph contains the points (1,1), (2,4) and (3,9), which are not on
a straight line.
8.F.4 - Construct a function to model a linear relationship between two
quantities. Determine the rate of change and initial value of the
function from a description of a relationship or from two (x, y)
values, including reading these from a table or from a graph.
Interpret the rate of change and initial value of a linear function in
terms of the situation it models, and in terms of its graph or a
table of values.
