options: 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.

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.

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

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.

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

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

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.

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

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.

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.
problem_activity: Narrative
The purpose of this activity is for students to put together pattern blocks to form larger shapes in more than one way. Students create hexagons using different combinations of pattern blocks. In the synthesis, students discuss whether the same pattern blocks in different orientations should be considered as different ways to make a hexagon (MP3). There is no one correct answer to the question. The goal is for students to notice and discuss that the same pattern blocks are arranged in different orientations.
MLR8 Discussion Supports.
To support the transfer of new vocabulary to long-term memory, invite students to chorally repeat these words in unison 1–2 times: more, fewer, the same as.

Required Materials
Materials to Gather
Pattern blocks
Launch
Groups of 2
Give each group of students pattern blocks.
“Work with your partner to find many different ways to make hexagons with pattern blocks. Tell your partner about the shapes that you use each time using ‘more’, ‘fewer’, or ‘the same number’.”

Advancing Student Thinking
If students find one or two ways to fill in the hexagon pattern block puzzle:
“Tell me more about which pattern blocks you used to make the hexagon.”
“Can you use these green triangle pattern blocks to make this red trapezoid pattern block? How can that help you find another way to fill in the hexagon?”
Activity Synthesis
Invite students to share different ways they made a hexagon.
As students share, say “Tell your partner about the shapes that they used using ‘more’, ‘fewer’, or ‘the same number’.”
Display all of the ways to make a hexagon that students have shared.
“Are there any other ways to make a hexagon with pattern blocks?”
Display 2 hexagons created with 2 blue rhombus pattern blocks and 2 green triangle pattern blocks in different orientations:

“Han and Clare shared these ways to make a hexagon with pattern blocks. Are these the same way to make a hexagon or a different way? Why do you think that?” (They are the same because they used the same pattern blocks but put them in different spots. It looks like they flipped it. They are different because the pattern blocks are in different places, so they look different.)
