Request for help
Students enrolled in EDTL 2740 need to conduct 2-4 hours in a
grades 7-8 learning environment as well as 2-4 hours in a high
school environment. If you’re willing to let students come into
your classroom then please let Dr. Bostic know. I’m looking for
your help. You can put them to work doing whatever you need
them to do, as long as it helps them better understand the life of a
teacher.
Warm-up Activity in Stats and Prob
What do frogs eat?
Evolving Norms for this PD
• We will be ready for class and use our class time effectively.
• We will keep our focus on learning and use technology for personal
reasons during breaks.
• We will be respectful of each other’s time and space and work
efficiently.
• We will actively participate by (a) listening to each other, (b) giving
others our attention, (c) not speaking when someone else is talking,
and (d) regularly sharing our ideas in class.
• If we disagree with someone or are unclear, we will ask a question
about his or her idea and describe why we disagree or are confused.
• We will ask questions when we do not understand something. We
will comment on others’ ideas rather than the person.
Evolving Norms for this PD
O We will take advantage of opportunities to share ideas and gather
feedback through presentations.
O We will encourage one another to share ideas.
O We will show our appreciation to one another after a presentation
by applause.
O If we disagree with someone or are unclear about their ideas related
to mathematics content and pedagogy, we will ask a question about
his or her idea and describe why we disagree or are confused.
O We will ask questions when we do not understand something about
mathematics content and pedagogy.
O We will comment on others’ ideas about mathematics content and
pedagogy rather than the person.
Evolving Norms for this PD
• We will always look for another approach to solve problems.
• We will use pictures, graphs, tables, symbols, numbers,
manipulatives, and/or words to assist us while doing mathematics.
• We will persist with every problem and examine it from multiple
perspectives.
• We will be mathematically precise whenever possible.
• We will explain and justify our ideas in a way that everyone can
understand.

1. Make sense of problems and persevere in
solving them
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the
reasoning for using them.
CCSS
7.SP.5 Understand that the probability of a chance event is a number between
0 and 1 that expresses the likelihood of the event occurring. Larger numbers
indicate greater likelihood. A probability near 0 indicates an unlikely event, a
probability around ½ indicates an event that is neither unlikely nor likely, and
a probability near 1 indicates a likely event.
7.SP.7b Develop a probability model (which may not be uniform) by observing
frequencies in data generated from a chance process
7.SP.8 Find probabilities of compounding events using organized lsts, tables,
tree diagrams, and simulation
What kinds of things do frogs eat? What
might their diet depend upon?
Habitat Bags
Bag 1: Marsh
Bag 2: Stream
Bag 3: Tropical Garden
==========================================
Each bag containing colored cubes: blue – flies,
green – worms, yellow – snails
Statistical Question of the Day:
What statistical question might we ask based on the information
we’ve been given?
“Is the probability of choosing blue, green,
yellow cubes different from bag to bag?” or
“Does habitat have any influence on a frog’s
food choice?”

Step 3:
Questions about your habitats:
• What is the most likely food choice from each habitat?
• What is the experimental probability of selecting the most
likely food choice from each habitat?
• What is the experimental probability of selecting a fly from
each habitat?
• What is the experimental probability of selecting a worm
from each habitat?
• What is the experimental probability of selecting a snail
from each habitat?
How can we gain better
estimates?
Answer to our question:
Is the probability of choosing
blue, green, yellow cubes
different from bag to bag?
Thinking through a Lesson
Read the article by Smith, Bill, and Hughes (2008). After
reading, jot notes for yourself about the following questions:
• What will I attend to in Part 1 of the TTLP? That is, what do
I perceive as key elements?
• What will I attend to in Part 2 TTLP? That is, what do I
perceive as key elements?
• What will I attend to in Part 3 of the TTLP? That is, what do
I perceive as key elements?
• Your lesson study group will agree on a subset of questions
for each Part and explicitly address them in your lesson.
Thinking through a Lesson
• Here’s the questions/prompts we used from the TTLP.
• Selecting and Setting Up a Mathematical Task
– What errors might students make?
– How will students record and report their work?
• Supporting the Students’ Exploration of the Task
– What assistance will you give or what questions will you ask a student (or group) who
become quickly frustrated and requests more direction and guidance in solving the
task?
– What will you do if a student (or group) finishes the task almost immediately? How will
you extend the task so as to provide additional challenge?
• Sharing and Discussing the Task
– What solution paths do you want to have shared during the class discussion? In what
order will the solutions be presented? Why?
– What specific questions will you ask so that students will expand on, debate, and
question the solutions being shared?

Lesson Study
Lesson study is a professional development process to systematically examine one’s
instructional practice, with the goal of becoming more effective. This examination
centers on teachers working collaboratively on a small number of "study lessons".
Working on these study lessons involves planning, teaching, observing, and critiquing
the lessons. To provide focus and direction to this work, teachers select an overarching
goal and related research question that they want to explore. This research question
then serves to guide their work on all the study lessons.
While working on a study lesson, teachers jointly draw up a detailed plan for the
lesson, which one of the teachers uses to teach the lesson in a real classroom (as other
group members observe the lesson). The group then comes together to discuss their
observations of the lesson. Often, the group revises the lesson, and another teacher
implements it in a second classroom, while group members again look on. The group
will come together again to discuss the observed instruction. Finally, the teachers
produce a report of what their study lessons have taught them, particularly with
respect to their research question.
Lesson Study: Action Plan
• Overarching goal:
• To collaborate in ways that help us improve our mathematics
teaching and learning and reflect upon those actions.
• Immediate goals:
• Each group will design, enact, reflect upon, and improve one
mathematics lesson per semester. This lesson will be taught
twice during one day by the same instructor.
• This is a learning process for everyone: the instructional
team, you, and your lesson study group. Be patient, flexible,
and open to trying something new.
Lesson Study: Action Plan
• Expectations:
• Lessons should provide outlets for co-teaching and offer rich learning
opportunities for ALL learners.
• The focal task should be a problem, not an exercise that is
immediately solved with a previously learned strategy. The problem
ought to be complex, open, and have realistic elements. The goal is
to promote problem solving, not efficiency with a known procedure.
You have approximately 45 minutes for your lesson.
• Ideas for promoting mathematical student-teacher and studentstudent discourse should be evident in the lesson. Questions
prompting mathematical discussions, including eliciting
misconceptions, must be present.
• The lesson should not be teacher-focused.
Lesson Study: Action Plan
1. In your lesson study group, discuss the TTLP. Your group
members should agree on 2-3 questions from each part that
you will address in this lesson.
2. Begin to frame your lesson using the “tool for planning…” and
keep the research question in mind:
“How does this lesson support students’ content learning
through engagement in the mathematical practices? “
Note: Your final lesson must be uploaded to the website by
11:59pm on Saturday, January 31. You will receive feedback that
week.
Synthesizing from the Day
1. What evidence from today’s PD that was indicative
of an effective learning environment? What are the
next steps for your group’s lesson? In other words,
what needs to be done by Friday?
Take Care
• Next meeting is Friday January 23 @ Lima HS.
• Please ask any questions to Dr. Stats and/or
Dr. Math.
• Most importantly, keep in touch!
