Identify Halves
๐ When you split something into 2 EQUAL parts, each part is called a HALF! Sharing a cookie with a friend? That's halves! Half means 1 out of 2 equal pieces.
Do this: Read the concept below, then try the quiz or activity.
Concept
Understanding halves is your first step into fractions!
๐ฏ What is a HALF? โข A half is ONE part when something is divided into TWO EQUAL parts โข Both parts must be THE SAME SIZE โข We write it as: 1/2 (say "one-half")
๐ Examples of Halves:
Example 1: Pizza Cut a pizza into 2 equal slices: ๐|๐ Each slice is 1/2 (one-half) of the pizza!
Example 2: Cookie Break a cookie into 2 equal pieces: ๐ช|๐ช Each piece is half of the cookie.
Example 3: Rectangle Draw a line down the middle: [โญ|โญ] Each side is one-half!
โ ๏ธ IMPORTANT: Equal Parts! The parts MUST be equal! โ These are halves: [โญ|โญ] โ These are NOT halves: [โญ|โญโญ] (not equal!)
๐ก Ways to Make Halves: โข Cut vertically (up and down): | โข Cut horizontally (side to side): โ โข Cut diagonally (corner to corner): /
All make halves as long as the parts are EQUAL!
๐ Half in Real Life: โข Half an hour = 30 minutes (half of 60) โข Half a dollar = 50 cents (half of 100) โข Half a dozen = 6 (half of 12)
๐จ Fraction Language: โข 1/2 = "one-half" โข The top number (1) = how many parts you have โข The bottom number (2) = how many equal parts total
