  1. Fractions Natasha Duffy Cockenzie Primary School

  2. FRACTIONS Learning Outcome I can… * explain what a fraction is. * explain what the denominator of a fraction is and find the denominator of a fraction. * explain what the numerator of a fraction is and find the numerator of a fraction. * write a fraction.

  3. WHAT IS A FRACTION? • When an object is divided into a number of equal parts then each part is called a fraction

  4. 2 numerator denominator 3

  5. 1 2 Denominator The denominator says how many equal parts in the whole object 2 equal parts

  6. 1 How many equal parts are there in this shape? What is the denominator of this fraction?

  7. 1 1 1 1 Find the denominators of these fractions

  8. 1 6 1 3 1 4 1 10 Draw what you think these fractions look like.

  9. 1 2 So, the number on the bottom of a fraction tells us… ? (Find a partner and discuss what you think the answer is)

  10. 1 2 numerator The numerator says how many parts in the fraction 1 part is coloured in

  11. 4 How many equal parts are coloured in in this shape? What is the numerator of this fraction?

  12. 4 3 8 8 Find the numerator for these fractions

  13. 2 6 1 3 3 4 9 10 Draw what you think these fractions look like.

  14. 1 2 So, the number on the top of a fraction tells us… ? (Find a partner and discuss what you think the answer is)

  15. 2 The numerator tells us… The denominator tells us… 3

  16. Find the fraction of these shapes
