Last week I realized how much hand-holding my calc II students needed so they could get started with parametric equations. Most of them are very weak in trig. Many of them aren't sure how to get started when they're doing something new with graphing.

So I slowed down. But I also wanted them to do more exploration and experimenting. On a whim I gave them the typical assignment to draw something using parametric equations (or polar graphs). It can be anything, be creative. I don't have a particular assignment yet.

Sometimes (for some students) less is more. One of my students emailed me with a question, I replied, we went back and forth with over a dozen emails, and he produced this loveliness. I've included a screenshot below, but what he did is animated, so click on over to Desmos.

Wow! I hope his enthusiasm inspires the rest of them!

### If We Knew How to Trust

-->

**If We Knew How to Trust**

we see the amazing
effort

young kids put into
learning to walk and talk

(this work is
their play),

and we know they are
capable

of miraculous feats of
learning.

if only we knew how to trust

their ability to
continue learning

just as powerfully and
miraculously,

maybe we could build a
school system

that would honor every
child’s fierce desire

to master the world’s
skills.

their differences
would no longer sort them

into good, mediocre,
and bad students,

but into artists, scientists, poets, musicians, mathematicians,

writers, inventors, leaders, organizers, and more.

and each child would
be many of these,

their differences
adding to their strength as a community,

their school an
ecosystem of learning.
