- Equipment check-in
- Updates
- Synthesis from Act 5 Responses
- Discussion of Act 6
- Unit Planning
- Assignment for Act 7 Discussion
- Wednesday, July 17
3Equipment Check
- What is the current status for your school
regarding computer access for the KVHS Algebra I
course?
4Synthesis of Act 5 Responses
- 1 Is x y lt 6 equivalent to 6 lt x y ?
- Attending to the process of reading for
inequalities and graphs from left to right and
once a mathematical sentence may require
reversing that process students have trouble. - Putting in the y mx b form to assist with
making meaning such as y lt -x 6 as opposed to
y gt -x 6 - Reviewing the Property of Symmetry for equalities
states that if A B, then B A while that
Property does not hold true for inequalities. - Substituting numerical values such as x 2 and y
-4 assist students in determining the nature of
the equivalency.
5Act 5 5, Importance of NAG
- Importance of using graphs or diagrams in
explaining mathematical ideas. How will pictures,
diagrams, or tables assist with solving word
problems? - Multiple Representations make connections for
students and provide a critical visual for making
meaning. - Connections from the visual to the abstract
assist in understanding the concept and serve as
a way to verify solutions. - Organizes thinking.
- Addresses various learning styles.
- Pictures, diagrams, and tables provide models
that can assist with translating the words into
mathematical symbols and creating possible
solution pathways.
6Act 5 6, The Distance Problem
- Takes Maria between 4.9 hours and 6.5 hours to
complete the trip to her brothers house. - Time is a conjunction, intersection, betweenness
statement 4.9 lt Time lt 6.5 Hours. - It should take Marie some where between 5 and 6
hours to get to her brothers house which is 320
miles away.
7Act 5 10, Proof for 0 gt 3
- Using numerical values to demonstrate that for
some a gt 3 the proof is not valid. - Providing justification/truthfulness for each
statement while showing that by dividing both
sides by a 3 (which is a negative number
because a gt 3), the order of the inequality must
be switched. - http//mathforum.org/library/drmath/view/53142.ht
ml provides a rationale for why the inequality
is switched when multiplying/dividing by a
negative.
8Act 5, General Comments
- Preciseness of communicating mathematical ideas
uses mathematical language that supports and
mirrors that Algebra is the Study of Structures
with certain properties. For example, rather
than - - flip around an equation speak of the
Symmetry Property that allows one to equate the
left to the right or right to the left sides if
A B, then B A. - - plug in speak of substituting equivalent
values because of the Substitution Property. - - cancel, speak of terms adding out or
dividing out because of the additive or
multiplicative properties of equality. - Graphs, Pictures, Models, Equations, Tables make
connections to equivalent forms all should tell
the same story (solution). - Always have students to show their thinking and
provide pictures and models of their
understanding. When asked to explain your
reasoning, expect mathematical work including
equations, tables, models (graphs, labeled
pictures), language that explains their
reasoning. - Model for them how to demonstrate mathematical
thinking and reasoning write while they write
show them your thinking.
9Small Group Discussion of Act 6
- Highlights regarding
- Content
- Instructional Strategies
- Reflections from Act 6
- Share-out
- Negotiate someone to speak for the group for each
strand - 2-3 main points for each
10Act 6 Scene 1
- How do I teach this?
- Rafting Problem
- Overlapping Circles
- Practicing Skills
11Getting Students to Connect to Solving Equations
- Multiple Representations
- Number Sense
- Diagrams (labeled drawings)
- Charts/Tables (charting ordered pairs)
- Symbolic Expressions (use of Real Number
properties) - Manipulatives (Algebra Tiles)
- Graphs (use of graphing calculators)
- Trace
- Y1Y2

12Act 6 Helping Students
- Scene 1
- Anticipating Student Difficulties
- Scene 3
- Shannons Work
13KVHS Algebra I to Spotlight
- Connections KVHS Algebra I to Spotlight
- Systems of Equations and Inequalities
- Unit 4, Lessons 15-19 in KVHS
- Act 6 in Spotlight on Algebra
14Planning Lessons using KVHS Algebra I Skill Set
from Spotlight on Algebra
- How will you bundle your Units for 08-09?
- What are the structures you will put in place to
support instructional strategies that motivate
students to engage in learning Alg I? - Refer to Strategies listed behind TAB 14
- For each structure, plan what formal feedback you
will provide to move students into their
zone of proximal development. - See Linking Formative Assessment to
Scaffolding, p 1
15Planning Instruction Using KVHS Alg. I
- What do you want the students to know and be able
to do? - How will you know that they know and can do?
- Formative
- Summative
- How will you use KVHS ALG I what lesson and in
what context? Will Spotlight on Algebra help?
How? - How will you access prior knowledge?
- What is the new learning? How will students keep
track and/or organize this learning? - What form of student/teacher reflection will you
use? - See Research Standards behind TAB 2
16Use of the Graphing Calculator within an
Authentic Context
17Expectations for Next Steps
- Work through all of Act 7 take notes and be
prepared to discuss for the Pedagogy Quiz post
responses to Numbers 1, 7- 8, 10. - Investigate KET Encyclomedia find one segment
that provides an access point for some critical
ALG I concept. Be prepared to share site location
and ALG I concept addressed. - Fill out the School Technology Database and send
to Roland by Thursday, July 17, 2008 - Group Times will alternate 9-11 Group becomes
the 2-4 Group while the 2-4 Group becomes the
9-11 Groups. - Have graphing calculators, notes from Act 7, and
research binders nearby. - Have open Spotlight on Algebra and the KVHS
Algebra I Course. - Make sure that ACT 5 6 Pedagogy Quiz responses
have been posted.
18- Thanks for sharing your thinking!
- See you Thursday, July 17, 2008
