Product of two proper fractions.

Class 5-5 learnt the product of 2 proper fractions today.
The first thing I showed the class is this,

Is the above correct? Are the answers the same?
We proceeded to proof this theory by models, which can also be found in their textbook pg 102.
Here's the diagram for easy viewing.

The class was then taught how to use the cancellation method to make multiplication of fraction simpler and easier.

To the class of 5-5, hope that you have learnt somehting new today.
