Wouldn’t it be awesome…


I can’t stop thinking about the great stuff from Penny Circle, Waterline, Central Park, Desman, and Function Carnival. Specifically the collaboration; the crowd sourcing of data and responses!

In Penny Circle, I love the fact that the student gets to do a few instances of selecting a circle and filling it with pennies. Then the data is grouped with the rest of the class….and voila!! we have a scatterplot!

I would love for this option of crowd sourcing content as a regular option. Wouldn’t it be awesome for when we complete the Vroom Vroom activity or the Barbie Bungee activity that we could ask students to record a few pieces of data in their table….like this,

but up on the projector the class sees this?

Wouldn’t it also be awesome if I asked the class to draw me a line with slope -2 ….the student would see theirs….

I’ve been using PearDeck for some lessons lately and we’ve been able to crowd source some stuff like..

Put the moveable point on A solution to the inequality f(x) > 40

Day 23 - Pear Deck!!

Day 23 – Pear Deck!!

We’ve also been able to crowd source by the old fashion way…….everyone write their points up on the board then we can all graph. This is still great don’t get me wrong……i’m just wishing!

Wouldn’t it also be awesome when we go to make Math Art with our Function Art project…..we all work together to make a picture like…

I know that Texas Instruments has TI Navigator which tries to link students up ……but in my opinion it’s not as nice or easy as Desmos is to use!!!! Maybe this is already possible in Desmos and I just don’t know it. Or maybe there is something else out there……but I doubt it.

I would love it if my class could all work together…..keep our technology social! These are just some wishes! Love Desmos no matter what!

    On it.

    Let me ask you: can you imagine a situation where you’d like students to see the combined view on their own devices, or should that only be on the teacher’s projector at the front?

      I would want them to have the combined view on their devices for those scatterplot activities and the others. But it would be super cool if they got ro plot their own line of best fit and NOT see the others so they could compete against eachother (make their own decisions).
      I think it would be great if the students could toggle the shared view with the single view. Kids could see their responses and then compare with everyone else! If that is the case, then the teacher wouldnt need to project at the front!
