Significant Figures Speed Dating Activity

My physical scientific discipline students are currently working on determining the right release of pregnant figures to utilization inward dissimilar situations.  The get-go footstep is for them to endure able to recognize how many pregnant figures at that topographic point are inward a number.  I made posters to hang upward inward my classroom for them (and me!) to reference, but I also wanted to create an activity to larn them upward as well as moving about.  I decided this was the perfect theme to build into a speed dating activity.  

You tin expose the files for my pregnant figures posters here.

To create cards for the speed dating activity, I typed upward 20 numbers into a Publisher file.

I tried to include numbers written inward scientific annotation as well as numbers written inward criterion form.  Then, I designed the file to impress the right release of pregnant figures on the dorsum of the carte du jour when printed double sided .

I printed them on pretty orangish cardstock (affiliate link) as well as laminated them at schoolhouse alongside my ever trusty Scotch build laminator (affiliate link).  

Here are what the front end of the cards looked similar when I was finished. 

And the backs of the cards:

And, I promise at that topographic point weren't whatever mistakes on the cards because I was variety of inward a rush to larn them made.  I idea I would own got enough of fourth dimension to larn them typed as well as printed earlier schoolhouse started, but I didn't concern human relationship for kids coming inward to larn assistance on making upward their quizzes!  So, if you lot create consider an error, permit me know as well as then I tin create it!  

The role of speed dating is to come across every bit many people inward every bit curt an amount of fourth dimension every bit possible.  In the few minutes you lot pass alongside the other person, you lot desire to expose something out nearly them as well as you lot desire to merchandise data inward instance you lot create upward one's withdraw heed to pursue things farther inward the future.  At to the lowest degree that's what I've gathered from watching speed dating on idiot box as well as inward movies.  I never truly went speed dating myself...

Here's how speed dating industrial plant inward my classroom:

Hand each modest fry a card.  I manus them out alongside the inquiry facing up.  I instruct kids to figure out how many pregnant figures are inward the release on their carte du jour as well as to cheque their reply alongside the dorsum of the card.  

Tell kids how speed dating works.  When you lot country them to larn up, they should expose a partner.  Each partner should concur upward their carte du jour for the other mortal to see.  Each mortal should country the other mortal how many pregnant figures they intend they have.  If correct, praise them.  If incorrect, bus them.  After both cards own got been answered as well as discussed, the partners should merchandise cards.  Then, they should larn as well as expose a novel partner.  This continues until the instructor calls stop.  (Bonus points for stopping kids past times ringing a bell similar actual speed dating!)  

Let them go!  Your undertaking every bit the instructor is to sentinel as well as expose the conversations.  Look for the questions that students expose tricky.  Listen to how students are explaining the concept to each other.  

Or, you lot powerfulness goal upward similar me as well as own got to participate yourself.  My physical scientific discipline degree had an strange release of students the twenty-four hr catamenia nosotros did this, as well as then I got to play along, too!  (This is also the argue why I don't own got whatever pictures of my students inward action.)  You'll but own got to settle for pics of the cards.  :)  

I've also used speed dating inward the past times to exercise switching betwixt exponential as well as logarithmic form as well as naming polynomials.
