demonstrate that small units such as building blocks can be combined or reassembled to form new objects for different purposes and explain the materials chosen based on their physical properties.
A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
demonstrate and explain that a whole object is a system made of organized parts such as a toy that can be taken apart and put back together.
demonstrate that small units such as building blocks can be combined or reassembled to form new objects for different purposes and explain the materials chosen based on their physical properties.
demonstrate that materials can be combined based on their physical properties to create or modify objects such as building a tower or adding clay to sand to make a stronger brick and justify the selection of materials based on their physical properties.
Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.
Cause-and-effect relationships are relationships between two or more variables or phenomena whereby one variable or event leads to a predictable response. Events have causes—sometimes simple, sometimes multi-faceted.
Engineers design and build new designs (effect) for a specific purpose based on specific criteria (cause).
A system is a whole made of parts that work together. It has components and boundaries. It can interact with or be part of other systems.
In a design (system), the engineer selects items and materials (parts) that depend on each other to create the product.
A structure is an organized arrangement of particles, parts, or elements in a substance, body, or entity. A function is the purpose or reason for something to exist in a system. The function of a structure depends on the shapes of and relationships among its essential parts. It is important to note that in kindergarten – grade 2, students focus on structures as an organized arrangement of parts within an organism or object.
An engineer will select materials based on their physical properties (structure) to serve specific roles (functions) in the overall design.
Math.2.2.A use concrete and pictorial models to compose and decompose numbers up to 1,200 in more than one way as a sum of so many thousands, hundreds, tens, and ones
Math.2.2.B use standard, word, and expanded forms to represent numbers up to 1,200
Math.2.3.B explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part
