Paper Folding-Fractions

Learning Goal: To develop the concept of a simple fraction as part of a whole Success Criteria- After this session you will be able to.. Fold paper to represent common fractions Fractions Terminology A fraction is part of a whole. We represent fractions using a specific form. Fractions are expressed in the form The top number a is called the numerator and tells you how many pieces you have of the whole. The bottom number is called the denominator and tells you into how many equal pieces the whole was divided. It represents the size of the parts

For Fraction Strips or Rectangles or Circles… REMEMBER: For Fraction Strips or Rectangles or Circles… The full piece of paper represents one whole, or 1. When folding, you need to fold it into equal parts.

Folding Paper KINDER Squares Squares and Rectangles Fractions can also be represented by the area (not the length) of a rectangle or square. EG A block of chocolate, a square cake of sticky date pudding, a netball court. We will be folding KINDER Squares.

KINDER Squares 1 Fold your square into halves. Show me ½. Stick in kinder square and/or write answer in book Fold your square into halves. Show me ½. Fold your square into quarters. Show me ¼. Can you do this another way? Show me with another KINDER Square. How many quarters are there in one half? How many quarters are there in two halves? Fold your square into eighths. Show me ½. How many eighths are there in one half? How many eighths are there in ¾? Show me ⅜.

KINDER Squares 2 Fold your square into thirds. Show me ⅓. Show me ⅔. Fold your square into sixths. Show me ⅓  How many sixths are there in ⅓? Show me ⅔.         How many sixths are there in ⅔? Look at both of your KINDER Squares. Which is bigger: ⅔  or ¾?  Show or tell me why.

Folding Paper KINDER Circles Fractions can also be represented by the area (not the radius) of a segment of a circle. EG Pizza slices We will be folding KINDER Circles.

KINDER Circles 1 Fold your circle into halves. Show me ½. Fold your circle into quarters. Show me ¼. • How many quarters are there in one half? • How many quarters are there in two halves? Fold your square into eighths. Show me ½. How many eighths are there in one half? • How many eighths are there in ¾? • Show me ⅜.

KINDER Circles 2 Get another KINDER Circle Fold your circle into thirds ‐ very tough! Remember that each part needs to be the same size/area. • Show me ⅓.         Show me ⅔. Fold your circle into sixths. Easier! • Show me ⅓  How many sixths are there in ⅓? • Show me ⅔.         How many sixths are there in ⅔? Look at both of your KINDER Circles. • Which is bigger: ⅔  or ¾?  Show or tell me why
