Good Afternoon,  
Our sixth grade teachers are incorporating the IQ robot in their math class. Does anyone have a lesson on Determine the volume of right rectangular prisms with fractional edge lengths? Any help will be appreciated. @Tina_Dietrich @AlainaHaws @Pe

Hi Desiree,

I’m still noodling on this one. I was thinking about it over the weekend and trying to determine how the 3D nature of a prism could be incorporated.

This might work well as a VR Activity instead where they could draw out each face of the prism? @Jimmy_Lin might have some ideas for how to make that work in the VR setting.

Let me think on it a bit more and get back to you 🙂

Perfect, thanks so much!

Hi Desiree!

Here is something I came up with for the IQ Kit.

One cool fact I learned while messing around with the kit is that the distance between each notch on an IQ beam is 1/2 of an inch. So by constructing these prisms with the IQ beams, students could actually create their own right rectangular prisms with fractional edge lengths!

Here is one I made while experimenting:

 ![IMG_6457](https://plc.pd.vex.com/uploads/default/original/2X/4/4f19811f95b71379adc535b59d1a7086f89d1c93.jpeg)  
 ![IMG_6458](https://plc.pd.vex.com/uploads/default/original/2X/7/7c460a3301d9641d35d00c16f91a4064d606671d.jpeg)

Students could create their own right rectangular prisms with the kit, which is also a great exercise in the spatial reasoning to create these shapes in real life using the corner connectors and such. Then measure their prism and determine the volume using the known equations.

For my example here, the dimensions are 4.5" wide x 6" long x 4.5" tall. So this gives some of those fractional measurements as well. This could continue as they create all different sizes of these prisms. If I was doing this in my classroom, I would probably have them make 3 different examples just to really dig into the building and then the measurement and calculation concepts.

This is awesome, thanks so much!
