• Thanks for the feedback Dane!

Keeping the launch question simple is a great idea and one that makes it even more accessible to an even larger group of students initially!

Thanks again!

• Great point, Dane.

My biggest challenge I’ve had since trying to make my math tasks more meaningful using 3 act and other visuals has been going with a “less structured” plan through the eye of the student. I’m only recently finding that when the task appears to be simple enough using only intuition with no clear indication that it will keep building do the students buy-in quickly. If it appears like too much work at the onset, some students may choose not to engage because they feel overwhelmed by the amount of work rather than the difficulty.

I’ve recently started doing all tasks at the whiteboard so students have nothing to work with except white space and each other. Only after the original task has been solved and shared out do I provide any sort of consolidation activity that extends the concepts. By then, I find that students are invested enough in the problem that they almost can’t disengage.

Keep up the work and I look forward to seeing more from you soon!

• This is an outstanding breakdown, Kyle! Thanks for sharing your process. I agree that students get overwhelmed if the task doesn’t appear simple enough at the start. That’s the low entry that so many talk about.
