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

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.

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

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.

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.

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.

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.

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

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 to introduce stage 2 of the Connecting Cubes center. Students use connecting cubes to make objects pictured on cards. As they work, observe whether students match the connecting cubes to the image or count the number of connecting cubes in the image to create their own object (MP6).
Required Materials
Materials to Gather
Connecting cubes
Materials to Copy
Connecting Cubes Stage 2 Cards
Required Preparation
Create a set of cards from the blackline master for each group of 2.
Launch
Groups of 2
“We are going to look at a new center that you can choose during center choice time.”
Display the student book.
“How could you use connecting cubes with this picture?” (We can make things with our connecting cubes that look like the picture in the book.)
30 seconds: quiet think time
1 minute: partner discussion
Share responses.
Activity
Give each group of students connecting cubes and a set of cards.
Display the student page.
“Use your connecting cubes to build this object.”
3 minutes: independent work time
“Choose another card and use your connecting cubes to build the object.”
