Grade 3

Writing Standards

CCSS.ELA-LITERACY.W.3.1 Write opinion pieces on topics or texts, supporting a point of view with reasons.
CCSS.ELA-LITERACY.W.3.1.A Introduce the topic or text they are writing about, state an opinion, and create an organizational structure that lists reasons.
CCSS.ELA-LITERACY.W.3.1.B Provide reasons that support the opinion.
CCSS.ELA-LITERACY.W.3.1.C Use linking words and phrases
CCSS.ELA-LITERACY.W.3.1.D Provide a concluding statement or section.
CCSS.ELA-LITERACY.W.3.4 With guidance and support from adults, produce writing in which the development and organization are appropriate to task and purpose. (Grade-specific expectations for writing types are defined in standards 1-3 above.)
CCSS.ELA-LITERACY.W.3.5 With guidance and support from peers and adults, develop and strengthen writing as needed by planning, revising, and editing. (Editing for conventions should demonstrate command of Language standards 1-3 up to and including grade 3 here.)
CCSS.ELA-LITERACY.W.3.7 Conduct short research projects that build knowledge about a topic.

Engineering Standards

3-5-ETS1-1  Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time or cost. ETS1.A  Defining and Delimiting Engineering Problems
Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account.
3-5-ETS1-2  Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem. ETS1.B  Developing Possible Solutions
Research on a problem should be carried out before beginning to design a solution. Testing a solution involves investigating how well it performs under a range of likely conditions.At whatever stage, communicating with peers about proposed solutions is an important part of the design process, and shared ideas can lead to improved designs.
3-5-ETS1-3  Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. ETS1.A  Defining and Delimiting Engineering Problems
Tests are often designed to identify failure points or difficulties, which suggest the elements of the design that need to be improved.

ETS1.C  Optimizing the Design Solutions
Different solutions need to be tested in order to determine which of them best solves the problem, given the criteria and the constraints.
