Virtual manipulative lesson

The use of ICT in teaching mathematics or science may help the lesson interesting and motivated the pupils to know more on the topic, example the use of virtual manipulative. Some pupils make the lesson as their first experience in using computers. There for teachers should give them more time to practice using the virtual manipulative. A few weeks ago we have a chance to conduct maths lesson using virtual manipulative from National Library of virtual manipulative ( http://nlvm.usu.edu/en/nav/vLibrary.html ). We choose topic on 'Adding fractions with unlike denominators' for year 5.
