Dear Lesson Planet,
I have looked through your lesson subjects for measurement to
find if you have a preference for SI. I do not find such s preference.
So, I ask, how do I send you recommendations?
Well, I might as well list them now.
1. Stop teaching inch-pound units (you call them conventional units).
2. Teach only SI units.
3. Stop teaching conversion. Do conversion only in algebra in upper
classes.
Who determines the content of lessons? Do you provide plans and
content as
requested or do you set the content?
The US wastes some $1000 billion each year by using two sets of
measurement units.
The US wastes about one year of K-12 school time teaching both.
What would it take to get rid of inch-pound units? Could you, Lesson
Planet, do this?
You ask for people to help with lesson plans. I could help but I am not
a teacher. I have a PhD in meteorology and am a registered
Professional Engineer. I concentrate on getting the US to drop
inch-pound units and to use SI units. I am a long-time member of the
US Metric Association. www.metric.org I am on the committee that
writes the SI standard SI 10.
If this does you any good let me know.
Please tell me about your ideas about teaching measurement.
