Reasons I Get Excited About STEM Challenges in Math

       STEM activities are all the rage, and my goal for this year is to make time for one STEM challenge each quarter this year.  I'll be honest, I'm fairly new to the STEM bandwagon.  Prior to 2016, I hadn't done any STEM challenges and I really had no plans to incorporate STEM in my classroom.  I figured that I had enough on my plate just trying to teach all of the stuff that was in my standards.

       That all changed in the summer of 2016 when I was privileged to attend Honeywell Educators at Space Academy.  Space Camp helped me realize that I not only need to teach my kids math skills.  I also need to help them see the exciting things that STEM can open up for them.  I need to help my students see themselves as people who are capable of using math as a tool solve problems.  So began my experience with STEM challenges.

     Over the last couple of years, I've found some STEM activities that really fit my needs.  This year, I plan to do a STEM challenge every quarter.  I've become a STEM challenge enthusiast, and here are the reasons why I love STEM challenges.

1.  STEM challenges are a great way for kids to really see the real world applications of math.  Let's face it....our textbooks try to use story problems to accomplish this task, but they are often not successful.  The contexts in story problems are often too contrived to make students care about them.

The beauty of a STEM challenge, however, is that you are giving students a problem to solve.  As they complete the challenge, math can be one of the tools that they use to find and gauge their success.

2.   STEM challenges are a place to really show the need for precise measurements.  Measurement of a variable is often the key to determining success in a STEM challenge.  If the challenge is to build the tallest pipe cleaner tower, accurate measurement is definitely a key.  In other STEM challenges, students must stay within given constraints.  For example, if you are only allowed to use 6 square inches of foil in your product, you will need to measure accurately for this.

3.  The need for correct labels is clear.  I was doing a STEM challenge last year where students had to build a shelf to hold as many quarters as possible.  They were given limitations for the size of the shelf, such as less than 6 square inches.  This STEM challenge really exposed my students' misunderstandings about the difference between inches and square inches.  Even better, it gave me a way to address this misunderstanding at a time that my students needed to know that information.

4.  STEM challenges are a great chance to introduce students to the power of spreadsheets.   STEM challenges often involve data collection, and this is a good way to incorporate the technology part of STEM.  Spreadsheets are a great way to collect the data. What a great way to introduce students to the power of a spreadsheet than with a bunch of data that they collected!  Last year we did a STEM pipe cleaner challenge, and there were so many excited students when I showed them that they could enter the calculations once and the spreadsheet could do all of the calculating for them.   In the real world that we live in, much of the math that we need can be automated with a spreadsheet.  It is so important for students to begin to see that math isn't always about doing the calculations yourself, but sometimes about knowing how to get a computer to do them for you!

5.  STEM challenges are a great way to work on a variety of math concepts.  Many STEM challenges involve measurement, data collection, and data analysis.  For many STEM challenges, however, the math part stops with these things.  However, I've found ways to incorporate many other topics:

• Area, surface area, and volume:  STEM challenges often involve creating some object, so I've found that I can often incorporate area, surface area or volume.  I did a STEM challenge last year where students had to build a diving pool for a daredevil high-diver (pencil cap erasers!).  After the challenge, students had to find the surface area and volume of their pool to see who had the pool with the least surface area.
• Percent change:  This works especially well if you give students a chance to improve their original creation.  For example, lots of STEM challenges involve students building tall towers.  I've seen these with spaghetti and marshmallows, pipe cleaners, cups, or even balloons!  To incorporate percent change, have the students complete the original project and measure their tower.  Then give them time to make revisions, or wait until another day and have them try again.  Then students can compare the percent change between the first and second attempt.
• Ratios:  I did one STEM challenge where students had to build a tower from candy and toothpicks.  The catch was that they were assigned a particular ratio of candy to toothpicks that they had to use. 
• Equations and inequalities:  I've found there are often ways to incorporate equations and inequalities into a STEM challenge.  Let's say your STEM challenge is for students to build a tower that is at least 12 inches tall.  Why not use this to introduce the idea of writing inequalities?  Or you could have all students put their tower heights on a number line, and introduce the idea of graphing inequalities.  When we built our candy/toothpick towers, we wrote equations relating the number of toothpicks to candy.

6.  STEM challenges are a great way to teach a growth mindset.  STEM challenges are all about trying things out and making adjustments to make things work better.   During a STEM challenge, it is no big deal to have something not work and try something different.  What a great opportunity for teachers to reinforce the power of learning from our mistakes to figure out better solutions or understandings.  I take any chance I can to reinforce the power of learning from our mistakes with my students.  

7.  STEM challenges are great for those random days that you don't know what to do with.  You know what I'm talking about....that 2 day week before Thanksgiving when you don't want to start something new.  Or that day when fourteen kids have the flu and you don't want them to miss the lesson that is such a foundation for your unit.  STEM challenges are great to fill in these random days, and yet still be focused on math.

8.  STEM challenges are great to engage all different kinds of students.  Kids love doing hands-on stuff and even my most reluctant math students will dive into a STEM challenge.

9.  They're fun!   We get so worried about teaching standards and finishing everything that sometimes the fun gets lost.  It's nice to hear the fun and excitement of a STEM day!  It's nice to hear kids in the hall talking about how much fun math is today.  It's nice to have kids still talking about something you did in class a week later.

10.  STEM challenges are a great way to get kids collaborating.  I always have my students work in groups on STEM challenges.  STEM challenges are a great way to get kids exchanging ideas, and incorporating ideas from many students.  This is a great way to work on "soft skills"!
