Five Paine Intermediate math teachers
attended the National Council of Teachers of Mathematics (NCTM) Regional
Conference in November 2013. We plan to bring all PI Math Teachers some
of the great things we learning in future professional development. Until
then, we will bring you our top three takeaways from the conference.
Nancy
1. Using the
number line more effectively.
2. Understanding the development of conceptual
foundation for teaching fractions.
3. Using reinforcement strategies for basic facts
fluency.
Laura
1. Number
lines are the central representational tool in teaching numbers.
2. Teaching strategies for mental math
and reinforcing with lots of practice and games (exposure) will help students
become proficient with numbers.
3. Kim Sutton taught us to be
enthusiastic with teaching and use music and dance to help kids understand
vocabulary which are the “tools” they will need in their “toolbox”.

1. Students should invent their own strategies which will allow
them to progress toward more efficient strategies. Students who invent their
own strategies progress much more efficiently to number sense/place value. From
intuitive numbers to one-to-one correspondence, as long as they are able to
invent ways on their own that make sense to them, they will progress to more
efficient addition & subtraction. Why should we not teach the algorithm
directly? Someone had clearly shown a little girl from a video the algorithm
& base ten blocks. When someone forces an algorithm on a child, they lose
confidence in their own thinking. The algorithm becomes precedent. This is why
the Common Core uses the phrase “develop, discuss and use.” Algorithms
are beautiful inventions if used correctly. (Note: Algorithms were invented by
someone at some point in time. It is actually the result of centuries of study
by mathematicians).
2. We should not be limited by the
Common Core. The mathematicians who influenced the common core said negative
numbers don't need to be in there until middle school, but students think in
terms of negative numbers. Let them! Here is how a student solved 61-43:
1-3= (-2). I took 40 away from 60 and that is 20 then I had to take
away 2. So I had to take away 2 from 20 which is 18! <-- This was amazing!!!
3. Precision, reasoning and thinking is
at the core of mathematics. Kids would be better off not to come to school than
to do ridiculous worksheets about geometry. Must move beyond basic shape
recognition. Less is more- focus on the building blocks. Go in depth rather
than exposure.

1. It was so great to see that we
are already doing such great things here at PI, especially when the NCTM
president spoke about the way to teach math – pose a problem/task, allow
students to investigate, then allow the children to discuss their work.
This is what we do every day!
2. I loved the session on fractions, especially all of the free
manipulatives! I hope to use the number line to help build conceptual
understanding when we start working with fractions this year.
3. The pre-algebra session was
also great! I can’t wait to start using some of the problems in my
classroom. They were so engaging, and I can see our students becoming
much better problem solvers!
Lisa
1. We were in one session with the NCTM President called “It’s
Raining Rich Problems!” She said to never “pull the pencil out of the
child’s hand by showing them”. Rather, question them to further their
thinking. She said productive struggle is a good thing; that is how
kids really learn.
2. She mentioned the 5 practices
for orchestrating mathematical discussions: 1) Anticipate (work the
problems yourself and have an idea of the strategies that may be used by
children), 2) Monitor (while students are working, converse with them and
decide which questions will further their thinking), 3) Select (select
strategies that will be presented for class discussion), 4) Sequencing (decide
which order these strategies should be discussed to scaffold learning), and 5)
Connecting (help kids connect the ideas). All of this sounds just like our
constructing tasks and congress.
3. Regarding constructing
conceptual knowledge first, one instructor stated, “Once you teach a procedure
first, it is nearly impossible for students to go back and understand the
reasons why behind it”; they block that out once the quick procedure is
revealed.
Sorry that it took me so long to post
this information. We will be incorporating what we learned into
CAD discussions and future PD sessions.
