2. Reading a Ruler Learning Target: KNOW HOW TO USE A RULER PROPERLY.
UNDERSTAND how to find halves (1/2), quarters (1/4) eighths (1/8), and sixteenths (1/16) measurements

4. #1 reason kids get measuring WRONG…not noticing where the 0 is located!
Notice where the "0" line falls on the ruler. Some rulers have this line at the exact edge of the ruler and other rulers place this line slightly to the right of the edge.
The location of the "0" line is important for accurate measuring because you must place this point on the ruler at the exact edge of the item or space you're measuring.
BOTH RULERS ARE CORRECT TOOLS FOR MEASURING! IT IS
YOUR REPSONSIBILITY
TO ALWAYS START MEASURING AT THE ZERO!

37. Reducing Fractions Review
Copy these steps in the Procedures Section of your binder
Reducing Fractions Review
Step 1. See if the numerator and denominator share a common factor (a number that will divide into both).
Step 2. If so, divide both numbers by the same factor. If not, the fraction is already reduced.
Step 3. Check to see if you can do the previous steps again.

38. Special Cases
Consecutive numbers (numbers that come after each other) are already reduced.
Ex. 𝟒 𝟓 𝟑𝟏 𝟑𝟐 𝟏𝟓 𝟏𝟔
If both the numerator and denominator end in zeros, you can cancel out the ones that correspond.
Ex. 𝟐𝟎 𝟓𝟎 = 𝟐 𝟓 𝟐𝟎𝟎 𝟓𝟎𝟎𝟎 = 𝟐 𝟓𝟎 = 𝟏 𝟐𝟓
