Dry Erase Workmat For Finding 5 Release Summary, Iqr, As Well As Outliers

My Algebra 1 students are inwards the midst of our next-to-last unit of measurement of the year: information analysis.  This is my kickoff yr of teaching Algebra 1 where my students create non own got to own got an end-of-instruction examination inwards Algebra 1.  This way that I don't own got to rush through concepts inwards guild to own got plenty fourth dimension to review for a seek out inwards Apr fifty-fifty though schoolhouse doesn't leave of absence until May.  Usually, our unit of measurement on information analysis is super-short every bit a result.  

This year, I own got plenty of fourth dimension to truly prepare my students' science at reading information displays too creating their ain information displays.  Today, I desire to percentage an action I created to give my students exercise alongside finding the 5 number summary too IQR of a ready of data.  Students thence used this information to depository fiscal establishment check for too position outliers.  

I started past times creating a workmat template inwards Publisher.  I purpose Publisher to create virtually all of the resources I postal service on my blog.  

I titled it "Identifying Outliers Practice," but it also gave my students exercise alongside finding the 5 number summary too IQR.  Not certain what I could championship it to include those every bit well...

I printed this workmat on 11 x 17 cardstock (affiliate link) that I slid into ane of my 11 x 17 dry out erase pockets (affiliate link).  I own got a ready of smaller, 8.5 x xi dry out erase pockets (affiliate link), too.  But, I prefer the 11 x 17 size (affiliate link) for partner work.      

I also created a ready of information value cards (1-36) that tally just into the information ready boxes on the operate mat. 

Each ready was cutting apart too placed inwards a tiny bucket from Dollar Tree. 

These stacked upwards really nicely betwixt classes!

Like many activities I create, I ended upwards modifying the action throughout the 24-hour interval to improve it too arrive to a greater extent than effective.  Originally, I had planned for each twain of students to whorl a 12-sided drib dead (from this set of polyhedra dice from EAI Education - affiliate link) to create upwards one's heed how many information values they should depict from their bucket before starting.   

My idea behind having them whorl a drib dead was that I wanted them to larn used to how to bargain alongside quartiles when in that location are an fifty-fifty number of values too an strange number of values.  

But, thence my students were ending upwards alongside information sets of 3, too the information exercise but wasn't rigorous enough. 

For my afternoon classes, I did away alongside the die too had each twain of students depict 12 information values from their buckets.  This ended upwards working soooo much better!  

As students worked, I circulated the room too checked for errors.  In the movie above, the IQR should truly live 18.5.

As pairs finished, they would enhance their hands to own got their calculations spot-checked.

One of the issues I didn't foresee alongside this action was that the bulk of students did non uncovering whatever outliers inwards their data.

It ended upwards beingness okay because afterwards I depository fiscal establishment check each pair's work, I would challenge them to create their ain information ready that had outliers.

This ended upwards beingness the perfect extension activity!

I dear how much collaboration I tin encounter alongside my students inwards these pictures!

There are a few changes I would similar to brand inwards the hereafter to this activity.

After students depict their information values too before they get doing whatever calculations, I would similar to own got my students brand a prediction re: outliers.

Then, afterwards they complete all of their calculations, I would similar them to write a judgement explaining why or why non the information contains outliers.  My students truly struggled alongside writing a judgement to justify their outliers on their quizzes.  Need to start practicing that earlier!  

Additionally, I would similar to create a ready of "challenge cards" for students to operate through.  For example, each carte du jour would say them how many cards to direct from the bucket.  Students mightiness randomly selection cards, or they mightiness selection specific cards to endeavor too reach a specific thing.
