Group A

We have learnt in class that a 4-pan balance can be useful in helping students understand solutions of linear equations better. We had fun playing with the balance in class as well.

I would like to share some sites that contains animation of pan balance to help students build up their algebraic thinking.

Pan Balance – Shapes 

One of the more interesting site, it allows students to guess the various weights of the shapes while incorporating the fun factor.

Pan Balance – Expressions

Expressions illustrate the relationship between 2 equations. However, it would be more useful for students who are learning simultaneous equations or solutions of equations using graphical method.

Pan Balance – Numbers

Numbers is useful to let students have a feel of what an equation means. It emphasize that equality is a relationship, not an operation.

The sites are self explanatory with clear instructions within it. Have fun exploring!
