  2. MAKE HALVES

  3. MAKE HALVES

  4. MAKE HALVES

  5. To get perfect half divide the circle from center.

  6. Two halves make one whole 1/2 + 1/2 = 1 1/2 1/2

  7. MAKE QUARTER

  8. Four quarters make whole1/4 + 1/4 + 1/4 + 1/4 = 1 1/4 1/4 1/4 1/4

  9. Fractions • Here is a whole square • There are everyday objects which are whole. For example, we can have a whole bar of chocolate • A fraction is an EQUAL part of a whole object

  10. Whole Fractions Here are more examples of whole objects.

  11. Half Fractions • When an object is evenly divided into two – each part is called a half • 2 parts make the whole object • ½ + ½ = 1 = +

  12. Half Fractions Here are more examples of whole objects which can be cut into half fractions.

  13. Quarter fractions • When an object is evenly divided into 4 it becomes a quarter • ¼ + ¼ + ¼ + ¼ = 1 + + + =

  14. Quarter Fractions • Here are more examples of ¼ fractions + + +

  15. Questions What fraction of the square is blue? What fraction of the rectangle is red?

  16. Questions • What fraction of this circle is red? • What fraction of this circle is blue?
