Why are you doing a Unit 4 webinar now? We aren’t even done with unit 1.
Wiki Questions Why aren’t 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 How are you letting districts know about changes in units? 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?
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?

Wiki Questions What does mathematize mean? Do you understand what it is like to be in a classroom?
So, there are the answers.
We can’t change how people think by telling them what we think and we can’t 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 can’t change how people think by telling them what we think and we can’t change how people teach by telling them how to teach.

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
How can we get support? Inquire at a local college or university. Mathematicians are inexpensive! Some are free…
Make time this year for the wiki and the webinars.
o Imitative Bad Math?
o Passive/receptive Bad Math?
o Minimal student explanations, comparisons Bad Math?
Worthwhile Task Teacher sets up the task…how? Supports include…what ? Suggestion included….what? Student ideas emerge, take form, and are shared….how? Conjectures are made and explored, and evolve into strategies…how? Strategies become retrievable practices…how? The plenary discussion at the end helps to cement these ideas….how and why?
Let’s talk a little more math…
Many math programs in the U.S. move from beginning ideas of counting and cardinality to addition and subtraction, “leaving students with a very limited collection of ideas about number... Resulting in children continuing to count by ones to solve simple story problems and difficulty mastering basic facts (Van de Walle, 2007, p. 124)
Very young children see a quantity as an aggregate of single units ‐‐ they need to count to find the total. They usually move on to abbreviate the count of one of the addends ‐‐ using “counting on” After more experience, they begin to see quantities as made by smaller chunks and become able to separate and combine these chunks freely. Bill Jackson, NCTM 2010
An important goal of early mathematics is students’ growth of flexible, fluent, accurate knowledge of addition and subtraction combinations. Learning these combinations is not only about rote memorization. Seeing and using patterns, and building relationships, can free children’s cognitive resources to be used in other tasks. Children generalize the patterns they learn and apply it to combinations that were not studied. Doug Clements: Learning and Teaching Early Math
This is the foundation of functional thinking because in order to see a number in relationship to another, we must pay attention to any dependency relationship or rule for correspondence. Tad Watanabe, 2008
Tad also says:
How are Number Talks Useful? Want more? number-of-the-day
Number Talk Who did the math thinking during the number talk? What specific mathematics did the students demonstrate they understood? What did the teacher do to support the student discourse? What recording techniques did the teacher employ that supported learning in the class?
How do teachers change practice?
