2. 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

7. MAKE QUARTER

8. Four quarters make whole 1/4 + 1/4 + 1/4 + 1/4 = 1 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?

17. Questions  How much of this triangle is coloured orange? How much of this triangle is coloured orange?
