Virtual manipulaitves in the maths classroom

The use of manipulatives in mathematics are essential for the teaching and learning of abstract concepts. Virtual manipulatives take this to a new level with  engaging graphics with dynamic generation and manipulation. Virtual manipulatives also have an advantage of allowing for universal access (at school or home). Research now suggests that the use of virtual manipulatives can lead to a deeper understanding of concepts when compare with concrete manipulatives.

Here’s a great article from the Center for Implementing Technology in Education on the use of virtual manipulatives in teaching mathematics (

Check out Matholia’s library of over 50 engaging virtual manipulatives found under the Tools tab on the Matholia home page.

Part-Whole Bar Model – Division

In the last post, we looked at the use of part-whole bar models for multiplication word problems. Here's a similar application of the part-whole bar model method – this time for a division word problem.

As with previous bar modelling videos, this video was produced using Matholia's 'Bar Model Maker' – just one of more than 50 primary maths tools available on the Matholia portal.  Email us now to start a free 3-month school trial now.

Part-Whole Bar Model – Multiplication

The use of bar models was first implemented into the Singapore maths syllabus approximately 30 years ago as a problem solving tool to assist pupils in visualising word problems. The pedagogy of bar modelling is now an integral part of the teaching and learning of primary mathematics in Singapore.

In this video, we look at how a part-whole bar model can be used to represent a multiplication word problem.

This video is part of the Matholia professional development video series. To see all of the videos in this series, follow this blog, or visit the Video Library on

Comparison Bar Model for Subtraction

As promised, here's a video demonstration using a comparison bar model to represent a subtraction word problem.

In the next videos, we'll look at how bar models can be used to represent word problems involving multiplication and division.

This series of training videos is produced using Matholia Tools. Tools are available on Matholia and can also be downloaded for free on  the iTunes App store.

The tools are just a small part of the comprehensive primary mathematics resources available on Matholia. Get your free trial account today!

Comparison Bar Models for Addition

A comparison bar model is useful for visualising word problems where a known quantity is compared to an unknown quantity. This video provides an examples of a comparison bar model for addition.

The above video was made using the Matholia Bar Model Maker. For loads more tools and comprehensive primary maths practice, head to the Matholia portal. In the next post, we'll look at how comparison bar models can be used to represent a subtraction word problem.
