Wiki Questions Why arent there answer keys? Has anyone at the state-level dug in and worked through the tasks as you are asking Georgia educators to do? Are these tasks vertically and horizontally aligned? Wiki Questions What about homework and other resources? Where and what are teachers suppose to pull for those? Are the tasks supposed to go home? How are parents supposed to help their children without books or other resources? How are you letting districts know about changes in units? TadWTadW Oct 5, :24 pm I have heard from Bill McCallum and Phil Daro that the CCSS does not discuss "simplifying" fractions because how we should use fractions depends on the contexts. In some instances, it may be useful to use the simplified form, but in other cases, a non- simplified form may be more informative. So, asking students to "simplify" a fraction without a context is meaningless - equivalent fractions are all equal and they represent the same number. In the same way, the Common Core does not specify that the "least common denominator" be used to add/subtract fractions. We just need a common unit Looked at LearnZillion yet? https://attendee.gotowebinar.com/recording/ Wiki Questions Do teachers have to complete all of the tasks? What about grades? Wiki Questions What about students who are not progressing as they should using only the tasks? What about students with disabilities? Need more? VandeWalle- ACTIVITIES AT A GLANCE Wiki Questions What does mathematize mean? Do you understand what it is like to be in a classroom? So, there are the answers. We cant change how people think by telling them what we think and we cant change how people teach by telling them how to teach. They have to experience good teaching first as a learner, then as a teacher. -a really smart person We cant change how people think by telling them what we think and we cant change how people teach by telling them how to teach. They have to experience good teaching first as a learner, then as a teacher. -a really smart person No support? On your own? How can we get support? Collaboratively solve tasks and discuss. Plan for the math by doing the math Learn alongside your learners Learn alongside your learners How can we get support? Inquire at a local college or university. Mathematicians are inexpensive! Some are free Does your district have a 10-15% ELL population? Make time this year for the wiki and the webinars. This is difficult. But not impossible. Sharing Candy Bars 5 th grade split into 4 groups. They shared candy bars as follows: 1 st group: 4 people shared 3 candy bars 2 nd group: 5 people shared 4 candy bars 3 rd group: 8 people shared 7 candy bars 4 th group: 5 people shared 3 candy bars Was this fair? Did people get different amounts? Whats the big idea? Deepen understanding of what a fraction is. Deepen understanding of equivalency. Develop an understanding of fractions as units which can be operated upon. Deepen understanding of properties of operations. Use multiple models to represent operations with fractions. Standards for Mathematical Practice. What about those transition standards? After your students do the first task from 5 th Unit 4, you may decide to go back and choose a few tasks from the 4 th grade Units (2, 3, and 4) to bridge understanding and address gaps. Suggestions: 4 th Unit 2- Fraction Kits, Equivalent Fractions, Making Fractions 4 th Unit 3- Sweet Fraction Bar, Rolling Fractions 4 th Unit 4- Bowl of Beans, Birthday Cookout Big important ideas Research - Communication The value of student interaction Challenges the teachers face in engaging students The teachers role Five strategies for encouraging high- quality student interaction 1.The use of rich math tasks 2.Justification of solutions 3.Students questioning one another 4.Use of wait time 5.Use of guidelines for Math Talk Mathematical Communication The development of students mathematical communication shifts in precision and sophistication throughout the primary, junior and intermediate grades, yet the underlying characteristics remain applicable across all grades. CBS Mathematics Mathematical Communication Mathematical communication is an essential process for learning mathematics because through communication, students reflect upon, clarify and expand their ideas and understanding of mathematical relationships and mathematical arguments. Ontario Ministry of Education Mathematical Communication Developing effective mathematical communication Categories of mathematical communication Organizing students to think, talk, and write Updating the three-part problem-solving lesson Gallery Walk Math Congress Bansho (Board Writing) Mathematical Communication Because mathematics is so often conveyed in symbols, oral and written, communication about mathematical ideas is not always recognized as an important part of mathematics education. Students do not necessarily talk about mathematics naturally; teachers need to help them learn how to do so. Cobb, Wood, & Yackel Mathematical Communication The role of the teacher during whole-class discussion is to develop and to build on the personal and collective sense- making of students rather than to simply sanction particular approaches as being correct or demonstrate procedures for solving predictable tasks. Stein, Engle, Smith, & Hughes Mathematical Communication When teacher talk dominates whole-class discussion, students tend to rely on teachers to be the expert, rather than learning that they can work out their own solutions and learn from other students.

Number Talk Who does the math thinking during the number talk? What specific mathematics do the students demonstrate they understand? What does the teacher do to support the student discourse? What recording techniques might the teacher employ that supported learning in the class? Assessment? Mathematical Communication Tips on Getting Started 1.Organizing the classroom learning environment 2.Preparing yourself mathematically 3.Coordinating student discussion and analysis of solutions Sharing Candy Bars 5 th grade split into 4 groups.
