September 17 & 18

Take a CLICKER and the

Metric System PRE Assessment

from my desk

Ensure you are completing the side that says PRE!!! (NOT ‘Post’)


On a scale of 1 5 1 being the least 5 being the most how confident are you with 1
On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with #1

  • No clue what’s going on

  • Kinda got it, but then you lost me

  • Ehh…I’m ok

  • I think I got it, but I’d like more practice

  • So confident I could teach it to someone right now


On a scale of 1 5 1 being the least 5 being the most how confident are you with 2
On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with #2

  • No clue what’s going on

  • Kinda got it, but then you lost me

  • Ehh…I’m ok

  • I think I got it, but I’d like more practice

  • So confident I could teach it to someone right now


In which problem was the math easier

Lesson 1 length

Lesson 1: Length CONFIDENT are you with #2

T. Trimpe 2008 http://sciencespot.net/


1 mile CONFIDENT are you with #2

1.6 kilometers

1 yard = 0.9144 meters

1 inch = 2.54 centimeters

English vs. Metric Units

Which is longer?

A. 1 mile or 1 kilometer

B. 1 yard or 1 meter

C. 1 inch or 1 centimeter

A. 1 meter or 105 centimeters CONFIDENT are you with #2

B. 4 kilometers or 4400 meters

C. 12 centimeters or 102 millimeters

D. 1200 millimeters or 1 meter

km

Metric Units

m

cm

mm

The basic unit of length in the metric systemisthe meterand is represented by a lowercase m.

Standard: The distance traveled by light in absolute vacuum in 1⁄299,792,458 of a second.

  • Complete each statement with Metric Units

    • 1 Kilometer (km) = 1000meters (m)

    • 1 Meter = 100Centimeters (cm)

    • 1 Meter = 1000 Millimeters (mm)

Which is larger?

Just like saying What's Larger? 100 cm or 105 cm

Just like saying What's Larger? 4000 m or 4400 m

Just like saying What's Larger?

120 mm or 102 mm

Just like saying What's Larger? 1200 mm or 1000 mm


Measuring Length CONFIDENT are you with #2

12 or 13 mm

1.2 or 1.3 cm

136 or 137 mm

13.6 or 13.7 cm


We are about to learn CONFIDENT are you with #2

DIMENSIONAL

ANALYSIS.

It’s a little different…

But after some practice, it’s easy 

(And you’ll need to know this in Chem and Bio)


Dimensional Analysis CONFIDENT are you with #2

How does the math work?

1030 cm = ______ m?

Multiply by aratio of 1

(just like ratios or fractions)

1030 cm .__1_m

1 100 cm

What CANCELS?

1030 m

100

What REMAINS?

SIMPLIFY & Solve 

…don’t forget the unit!

10.30 m

OR

10.3 m


Use CONFIDENT are you with #2Metric Magic and Dimensional Analysis to complete the following problems. Need help? Ask a friend or ask a teacher. SHOW ALL WORK, round to at least 2 decimal places!

FIX # 5, 7, 8!!!! (They use ‘l’ instead of ‘L’

ALSO – depending how you round, your answers might vary slightly!!!

Do you prefer
Do you prefer… CONFIDENT are you with #2

  • Dimensional Analysis (I’m a numbers person!

  • Ladder Method (way easier)

  • Either – I can see the benefits of both methods


On a scale of 1 5 1 being the least 5 being the most how confident are you with the ladder method
On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with the LADDER METHOD

  • No clue what’s going on

  • Kinda got it, but then you lost me

  • Ehh…I’m ok

  • I think I got it, but I’d like more practice

  • So confident I could teach it to someone right now

EXIT SLIP CONFIDENT are you with DIMENSIONAL ANALYSIS

  • Complete the Post Assessment

    (on the BACK of your PRE assessment)

    Use either LADDER METHOD or DIMENSIONAL ANALYSIS!

  • Turn in at the in box

  • This is not for a grade, but we will return to this next class

  • Take a copy of your HW

    This is not for a grade, but we will REVIEW this next class
