Big Idea(s)
What enduring understandings are
essential for application to new
situations within or beyond this
content?
Unit 4: Geometry
• Draw, construct and describe geometrical figures and describe
the relationships between them.
• Solve real-life and mathematical problems involving angle measure,
area, surface area, and volume.
Essential Question(s)
What questions will provoke and
sustain student engagement while
focusing learning?
How is the circumference of a circle used to derive the area of a
circle?
How are area and volume properties related?
How can I use a model to help me solve this problem?
Enduring Standard(s)
Which standards provide
endurance beyond the course,
leverage across multiple
disciplines, and readiness for the
next level?
Enduring Understandings
• Use freehand, ruler, protractor and technology to draw geometric
shapes with give conditions.
•Construct triangles from 3 measures of angles or sides.
•Solve real-world mathematical problems involving area, volume and
surface area of two-and three-dimensional objects composed of
triangles, quadrilaterals, polygons, cubes, and right prisms.
Standards for Mathematical Practice
*1. Make sense of problems and persevere in solving them.
Students make sense of the problems involving geometric
measurements (area, volume, surface area, etc.) through their
understanding of the relationships between these measurements.
They demonstrate this by choosing appropriate strategies for
solving problems involving real-world and mathematical situations.
2. Reason abstractly and quantitatively. Students represent a wide
variety of real world contexts through the use of real numbers and
variables when working with geometric figures. Students
contextualize to understand the meaning of the number or variable
as related to a geometric shape. Students must challenge
themselves to think of three dimensional shapes with only two
dimensional representations of them on paper in some cases.
3. Construct viable arguments and critique the reasoning of others.
Students are able to construct arguments using concrete referents
such as objects, drawings, diagrams, and actions. Such arguments
can make sense and be correct, even though they are not
generalized or made formal until later grades.

4. Model with mathematics. Students are able to apply the
geometry concepts they know to solve problems arising in
everyday life, society and the workplace. This may include
applying area and surface of 2-dimensional figures to solve interior
design problems or surface area and volume of 3-dimensional
figures to solve architectural problems.
*5. Use appropriate tools strategically. Mathematically proficient
students consider available tools that might include concrete
models, a ruler, a protractor, or dynamic geometry software such
as virtual manipulatives and simulations. When making
mathematical models, they know that technology can enable
them to visualize the results of varying assumptions, explore
consequences, and compare predictions with data.
*6. Attend to precision. Students continue to refine their
mathematical communication skills by using clear and precise
language in their discussions with others and in their own reasoning.
Students determine quantities of side lengths represented with
variables, specify units of measure, and label geometric figures
accurately. Students use appropriate terminology when referring to
geometric figures.
*7. Look for and make use of structure. Mathematically proficient
students look closely to discern a pattern or structure. They
recognize the significance of an existing line in a geometric figure
and can use the strategy of drawing an auxiliary line for solving
problems. They can see complicated things as single objects or as
being composed of several objects.
8. Look for and express regularity in repeated reasoning.
Mathematically proficient students notice if calculations are
repeated, and look both for general methods and for shortcuts.
Standards for Mathematical Content
Draw, construct, and describe geometrical figures and describe the
relationships between them.
7.G.1 Solve problems involving scale drawings of geometric figures,
including computing actual lengths and areas from a scale drawing
and reproducing a scale drawing at a different scale.

Solve real-life and mathematical problems involving angle measure,
area, surface area, and volume.
7.G.4 Know the formulas for the area and circumference of a circle
and use them to solve problems; give an informal derivation of the
relationship between the circumference and area of a circle.
7.G.5 Use facts about supplementary, complementary, vertical, and
adjacent angles in a multi-step problem to write and solve simple
equations for an unknown angle in a figure.
7.G.6 Solve real-world and mathematical problems involving area,
volume and surface area of two- and three-dimensional objects
composed of triangles, quadrilaterals, polygons, cubes, and right
prisms.
