Elko County School District CCSS Math Professional Development Module 3, Week 2 Digging into the CCSS, part 1

Science has found that the elegance of mathematics often underlies the beauty of nature. Mathematics can be used to explain the shape of the world around us, particularly geometry.

Domain: Geometry, K-6 Like core knowledge of number, core geometrical knowledge appears to be a universal capability of the human mind. Geometric and spatial thinking are important in and of themselves, because they connect mathematics with the physical world, and play an important role in modeling phenomena whose origins are not necessarily physical… -The Common Core Standards Writing Team Teacher Task: Read through your grade level standards.

We will… Target a mathematics domain. Chunk the main categories within the standard. Identify the developmental progression of the standards. Identify the standard components in Geometry Use the Progressions Document to understand how domains are connected across grade levels.

Week 2 Step 1: Target a standard Step 2: Chunk the Main Categories Step 3: Identify all standard components Step 4: Identify the Developmental Progression Week 3 Step 5: Identify Key Vocabulary Step 6: Add Clarifying Information Critical Areas of Focus To increase student achievement by ensuring educators understand specifically what the new standards mean a student must know, understand, and be able to do. (Unpacking) may also be used to facilitate discussion among teachers and curriculum staff and to encourage coherence…(Unpacking), along with on-going professional development is one of many resources used to understand and teach the CCSS. -North Carolina Dept of Public Instruction

To understand what the standards are asking students to know, understand, and be able to do To make time for professional discussion about the standards To build upon and use common terminology when discussing the implementation of the standards Unpacking is standards is not a substitute document for the Common Core Standards, it is a record of the conversation of those who are involved in the process of digging into the standards.

Example 2.G.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape. 1. All Standard(s) in the cluster(s) 2. Identify Key Verbs 2.G.3 Partition circles and rectangles into two, three, or four equal shares DescribeRecognize Partition

Components from CCSS: Analyze nouns and verbs What do students need to do? Include bullets, examples, footnotes, etc. Take standard apart according to the verb to separate skills within the standard What do the students need to know? blue

Questions to consider when looking at the developmental progression of the standards… How would you utilize these chunks (blue) for scaffolding toward mastery of the entire standard? Where would you start when teaching this standard? What is the chunk that demonstrates the highest level of thinking?

The Progressions Document is a narrative description about how a particular domain plays out across the grade levels. (McCallum 2011) Read: 1. Scan to find your grade level within the Progressions Document. 2. Read and code the text. 3. If time permits, read the grades above and below your own grade level. ? = Question I have ! = Ah Ha

They(Geometric and spatial thinking) are also important because they support the development of number and arithmetic concepts and skills. Thus, geometry is essential for all grade levels for many reasons: its mathematical content, its roles in physical sciences, engineering, and many other subjects, and its strong aesthetic connections. -The Common Core Standards Writing Team

Using the progression document(s) from Ohio Department of Education and CCSS Writing Team: Look to the grade level(s) below to see if the standard is introduced. Look to the grade level(s) above to see if the standard is continued. Code each standard on the poster with: builds on introduced needed for or mastered and the grade level to which the standard aligns.

Introduced? Mastered? Needed for? Builds on? 2.G.3 Partition circles and rectangles into two, three, or four equal shares PartitionRecognizeDescribe Partition circles and rectangles into four equal shares, using the word fourths, fourth of 2.G.3 Describe the whole as two halves, three thirds, four fourths 2.G.3 Recognize that equal shares of identical wholes need not have the same shape 2.G.3 Partition circles and rectangles into three equal shares, using the word thirds, third of 2.G.3 Partition circles and rectangles into two equal shares, using the word halves, half of 2.G.3 Builds on 1.G.3 Needed for 3.G.2

How did todays training impact your understanding of these standards? No impact Some impact Significant impact What ah-has did you have today? What questions do you still have about this domain?
