options: Ratios & Proportional Relationships: students learn to recognize, describe, represent, and reason with ratios, rates, proportional relationships, and percent.

Counting & Cardinality: students learn to know number names and the count sequence, count to tell the number of objects, and compare numbers.

Number & Operations in Base Ten: students learn to work with the base-ten system and build place value understanding.

Statistics & Probability: students learn to analyze and produce data distributions, and build understanding of univariate and bivariate data. They learn to interpret data, make statistical inferences, justify conclusions, understand rules of probability, and use probability to make decisions.

Number & Operations - Fractions: students learn to understand fractions as numbers and may work with them using addition, subtraction, multiplication, and division.

Operations & Algebra: students learn to solve problems using algebraic thinking and operations such as addition, subtraction, multiplication, and division. They may learn to identify and explain arithmetic patterns, evaluate or manipulate numerical expressions, and reason with equations and inequalities.

Measurement & Data: students learn to work with data and measure attributes such as time, money, length, area, and volume. They may learn to compare measurements to operations and convert between different units of measure.

Number Systems and Quantity: students learn to understand the complex number system and reason quantitatively.

Functions: students learn to define, use, and evaluate functions to model relationships between quantities.

Geometry: students learn to classify geometric figures by their properties, and understand and compare the relationships between them. Students develop and use formulas to compute lengths, areas, and volumes, and they use transformations to generate new shapes and compare existing ones. Geometry can be studied with and without coordinates.

Modeling: students learn to choose and use appropriate mathematics and statistics to analyze real-world empirical situations, improve decisions, and report on their conclusions and the reasoning behind them.
problem_activity: Narrative
The purpose of this activity is for students to practice drawing and describing figures with points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines.
Students draw two-dimensional figures and then describe it to their partner. Their partner attempts to draw the figure without seeing it, making it important to use precise language to communicate important features of the figure (MP6).
Representation: Develop Language and Symbols.
Provide students with access to definitions or reminders of recently learned terms, such as: ray, line segment, right angle, acute angle, obtuse angle, perpendicular lines, parallel lines.
Supports accessibility for: Memory, Conceptual Processing, Attention
Required Materials
Materials to Gather
Rulers or straightedges
Launch
Groups of 2
Activity
5 minutes: independent work time
8–10 minutes: partner work time
Monitor for diagrams that reflect a variety of geometric features.
Monitor for students who consider both geometric features and measurement in the description.
Student Facing
Create a two-dimensional shape that has at least 3 of the following:
ray
line segment
right angle
acute angle
obtuse angle
perpendicular lines
parallel lines
Without showing your partner, describe the figure so that your partner is able to draw it as best as possible.
Switch roles, and draw your partner’s shape based on their description.

Activity Synthesis
Invite previously selected students to share.
“What would have helped your partner make a more accurate drawing?” (If I described the measure of the angle, measure of the line segment, the location, a grid, using a straight edge)
