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.
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.
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 www.matholia.com.
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.
