Problem Based Learning (PBL) - A Short Introduction

Problem Based Learning In Math

A Teacher's Guide To Problem Based Learning
(Some Parts Specific "To Splash - or - You're All Wet!" )
For those New to PBL

Problem Based Learning (PBL) “problems” may be different from most of the math “problems” you have encountered in your teaching experience.

Rather than “teaching” knowledge and skills aligned to the common core, and then testing to see what students have been taught, in PBL we present the student(s) with a real world problematic situation that includes an outline of “the test”. In the case of "Splash - or - You're All Wet!", the test is stated in the last paragraph of the introductory page:
“Your task is to consider all of the data gathered for the five city pools, and to consider the wishes of the citizens of the city, and then to make a recommendation to City Council concerning what, if anything to do about the city's swimming pools next summer.”

Implicit in the problematic situation and the “test”, is the need to be able to master many common core, math concepts things such as:
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
(Common Core – Mathematical Practices)

and
Represent and interpret data.
(Common Core – Standard - Grades 1-5)

The scope of things to be learned in this activity is fairly limited. This PBL activity is designed as a manageable introduction to PBL, both for your students and for you the facilitator. The activity is designed to last no more than a few days to a week or so, depending on whether you meet with your students every day, or see them only a couple of times per week, as do some teachers of the gifted. It can also be used as a math center activity for advanced students.

Students should find themselves struggling to LEARN what they need to know to do what the “test” asks them to do. Your role is less that of a teacher and more of a facilitator / mentor. You should avoid teaching anything about the representation and interpretation of data to your students. On the other hand you should provide multiple resources (This is the time consuming part of a full scale PBL activity) that the students can use on their own TO LEARN about the representation and interpretation of data. .

As students begin to come to conclusions about the pools in Capitol City, and what, if anything, should be done about them next summer, you must again refrain from expecting “one right answer”. In fact, as PBL facilitators, we really don't care what answer the individual or group decides to pursue –
AS LONG AS THEY CAN SUPPORT IT WITH THEIR
DATA REPRESENTATION AND INTERPRETATION.

Sometimes it is tough to “let go” and allow students to develop a plan, that is not what we would do, or what we really would like to see them do. However the goal is not a pristine student plan, but rather (in this case - quality data representation and interpretation) seeing students LEARN the content and then USE what THEY HAVE LEARNED.

In a nutshell – PBL emphasis is much less on teachers teaching, and much more on students learning, (mostly on their own – with resources provided) and showing what they have learned in a real world or a simulated real world setting.

Teach– Model – Then sit back and watch students have fun learning and sharing what they know and discover, with each other.

The World's Oldest Subtraction Game


Who Knew Subtraction Was A Contact Sport ????
OK, not real contact, but more fun than most recess games.
NIM and nim-like games have existed ever since – well.... ever since games. The beauty of nim-like games lies in their physical simplicity (a pile of pebbles or pennies, and easy rules) and their mathematical complexity.
From simple (but sometimes frustrating) subtraction strategy to complex number theory and computer code generation, NIM is a great game for Kindergarten (take away) through high school (binary number systems & computer programming) students.
“NIM” challenges students to think ahead (or maybe thinking backwards would help) as they remove (subtract) pebbles, seashells, pennies or other 'markers” from distinct piles.
Their goal is to leave just one “marker” for the other player to remove. The person who removes the last marker “looses."
But nobody looses as they stretch their mathematical thinking and begin to develop an algorithm or strategy for winning.
You can access a FREE DOWNLOAD of several versions of the game along with instructions and differentiation strategies here:
After your students use and learn from it, a quick shout here and/or on my Teachers Pay Teachers page would be appreciated.
Differentiated Instruction ideas are included for students from emerging math students in Kindergarten through gifted 7th & 8th graders.

This challenge activity is a great tool for:
Teaching specific math skills.
Allowing students to develop and test number theories.
Math Centers

"33 Points"

Much like the game "21 Answers" from my previous post, "33 Points" challenges students to use three single digit numbers and all the math they have ever learned  to create expressions and number sentences in order to arrive at pre chosen "answers."

But That's Just The Beginning - Students Use Strategy To Capture Adjacent Numbered Points For
Bous Scores!

You can access a FREE DOWNLOAD of the game along with instructions and differentiation strategies here:


After your students use and learn from it, a quick shout here and/or on my Teachers Pay Teachers page would be appreciated.
Never mind that this is just good higher level thinking, common core math standards are included for those pesky principals who demand them with your lesson plans.
Differentiated Instruction ideas are included for students from emerging math students in first grade through gifted 5th & 6thgraders.
This challenge activity is a great tool for:
Teaching specific math skills.

"21 Answers"

Rollo (not his real name) leaped from his chair, thrust his arms in the air and yelled, “I'VE GOT IT !” Shhhh,” I laughed, “You'll get us all in trouble.”
 
I was working with a half dozen able math students at a table in the back of a regular classroom, while the regular teacher worked with another group and one of the special ed teachers worked with a third.
 
One of the less emotional students was actually smiling at himself for seeing a relationship among numbers, and jet another was actually shaking with anticipation as she got closer to a really complex answer. Oh..... yes..... we were playing a game.
 
More about the value of games in teaching number sense and new math skills later. For now, it is enough to know that in order to come up with “21 Answers” students created and experimented with over 150 expressions and number sentences. That's a lot of math!

In the mean time, as a quick overview, “21 Answers” challenges students to use three single digit numbers and all the math they have ever learned to create “21 Answers” from 0 – 20.

Never mind that this is just good higher level thinking, common core math standards are included for those pesky principals who demand them with your lesson plans.
Differentiated Instruction ideas are included for students from emerging math students in first grade through gifted 5th & 6th graders.

Why "The No Explosion Zone"

I am a very blessed teacher. I'm itinerant – like the “Art on A Cart” teacher – but I work mostly with academically gifted kids.

I'm blessed partly because I get to see some of the most amazing teachers, do amazing things in their classrooms!

On the other hand, I also get to see how difficult it is for so many teachers to struggle – being asked every year (sometimes every grading period) – to do more with less.

Someone once told me the logical end of always doing more with less, is to finally ….....

Do Everything With Nothing!

It is enough to make a teacher's head EXPLODE.
-----------------------------------------------------------
A (very little) bit about me.

I have just enough gray hair to make me wonder why anyone would ever pay attention to me.

On the other hand, I seem to have other teachers asking me if they can have copies of my “stuff” – the things I use or share with other teacher in my buildings (remember I said itinerant.) to help them either do more with less, or to do more things at the same time – To meet the needs of multiple groups of students at the same time, without having their head explode.
-----------------------------------------------------------

So.... here we go. A serious attempt at blogging. My other “attempts” have been short lived.
“If you're obsessive compulsive and ADD, things have to be perfect.......
but not for very long” - anon.


My commitment to you is to get “stuff” to you on a regular basis (even if it isn't perfect- but you know it's gotta be close since..... there I go again) and on a consistent schedule ( If I wasn't so ADD I'm sure I could get things to you on a more regula........ anybody want to go on a photo safari?)
