Author: Rebecca Tresino, Sun Valley Jr./Sr. High, AK

Grade Level/Subject: Math - Secondary Students

Overview:

Students will use a shortcut method to change one metric unit to another (ex: kilometers to centimeters), by using a diagram which uses words students can relate and remember.

Purpose: To simplify metric equivalents.

Objectives: Students will be able to convert a metric measurement to another, easily and quickly.

Activities:

```          K  H  D   (unit)    D  C  M
---------

which stands for:

K  H  D   (meter)    D  C  M
i  e  e   --------   e  e  i
l  c  k              c  n  l
o  t  a              i  t  i
o                    i

students will remember:

K  over  H over  D over  ______  D over  C over  M
i        u       r               o       a       o
n        m       a               g       t       u
g        a       g                               s
s        n       o                               e
s       n
s

```
1. You will decide what unit you are changing FROM and what unit you are changing TO.
2. Starting at the FROM unit, count over (keeping in mind "left" or "right") to the TO unit.

**This will be the number of places you will move the decimal in your answer.

Examples:

32 kilograms = ______________ grams

You want to change FROM kilograms TO grams. Use diagram and count over, starting at kilograms to grams.

```   K  H  D    (grams)  D  C  M
--------
-> 1->2->   3

**(3 places to the right)
```
Now we use this information (3 places to the "right") and apply to the given information - 32 kilograms.
```   given info       3 places to the "right"
-----------      -----------------------
32 kilograms  =     32.000.  =  32000

32 kilograms  =  32000 grams
