Fractions 6 (Addition and Subtraction)

Number Powerpoint Presentation

Fractions 6 (Addition and Subtraction)

The presentation starts off by concentrating on visualising fractions added together by use of an 8 sector circle. Each of the sectors fill slowly as you click the mouse. This is followed by an extensive selection of addition problems using a 12 sector circle. We then move on to adding fractions with different denominators by considering diagrams to help explain equivalence. Again, you control the fill effects. This is followed by some routine problems without diagrams. A similar approach is taken for subtraction.
An excellent presentation for your resource library! Don't be without it.
