## General Course Information and Notes

### Version Description

This course offers students an opportunity to deepen science, mathematics, engineering, and technology skills. The primary content focus will be to expand knowledge of current grade level standards in mathematics and science by applying that content in a real world, hands-on situation involving engineering and technology. For third grade, themes will focus on the investigation of number sense, measurement, geometry, life science, and physical science concepts.

Students will participate in various hands-on STEM activities in this supplemental course to assist in the mastery of current grade level mathematics and science standards.

**Instructional Practices **

Teaching from a range of complex text is optimized when teachers in all subject areas implement the following strategies on a routine basis:

- Ensuring wide reading from complex text that varies in length.
- Making close reading and rereading of texts central to lessons.
- Emphasizing text-specific complex questions, and cognitively complex tasks, reinforce focus on the text and cultivate independence.
- Emphasizing students supporting answers based upon evidence from the text.
- Providing extensive research and writing opportunities (claims and evidence).

**Science and Engineering Practices** (NRC *Framework for K-12 Science Education, 2010*)

- Asking questions (for science) and defining problems (for engineering).
- Developing and using models.
- Planning and carrying out investigations.
- Analyzing and interpreting data.
- Using mathematics, information and computer technology, and computational thinking.
- Constructing explanations (for science) and designing solutions (for engineering).
- Engaging in argument from evidence.
- Obtaining, evaluating, and communicating information.

**English Language Development (ELD) Standards Special Notes Section:**

Teachers are required to provide listening, speaking, reading and writing instruction that allows English Language Learners (ELL) to communicate information, ideas and concepts for academic success in science and math. For the given level of English language proficiency and with visual, graphic, or interactive support, students will interact with grade level words, expressions, sentences and discourse to process or produce language necessary for academic success. The ELD standard should specify a relevant content area concept or topic of study chosen by curriculum developers and teachers which maximizes an ELL's need for communication and social skills. To access an ELL supporting document which delineates performance definitions and descriptors, please click on the following link: {{AzureStorageLink}}/uploads/docs/standards/eld/sc.pdf.

For additional information on the development and implementation of the ELD standards, please contact the Bureau of Student Achievement through Language Acquisition at sala@fldoe.org.
