We are studying fractions in grade 6, in my experience students often know shortcuts and tricks to do equations with fractions
While this approach gives them an answer it doesn't promote understanding, rather it focuses on answers. I am much more interested in students understanding a concept rather than knowing an answer. Often they don't understand what the equations actually mean and written explanations are complicated and confusing.
Keynote Fraction Animation
Magic move compares one slide to the next, takes note of any changes and then animates the changes. You can easily duplicate a slide, make some changes and turn it into a nifty animation in no time at all.
Here are a series of videos I created on how to make your own fraction animations the first two use regular animations and the second two (multiplication and division use magic move)
What I really like about this activity is that it is hard work, the students really need to think about what it means to perform operations on fractions. What does it mean to add fractions beyond a set of rules.
They look at fractions and operations in different ways, work backwards and need to problem solve to make their animations reflect what is actually happening when performing operations on fractions.
