Why use bar model multiplication and division
Children begin learning simple multiplication and division in early years. The concept of multiplication is typically introduced by adding the same number together multiple times. By using a bar model, teachers can demonstrate that one whole can be divided into equal, smaller parts.
Teachers can draw bar models to demonstrate this:
By drawing a bar model and separating the bar into equal parts, children can visualise the process of multiplication and division and how they have an inverse relationship.
Bar models and problem solving
Bar models are particularly useful when it comes to solving one-step multiplication word problems, two-step maths problems and multi-step word problems. Bar models enable students to extract the most important information to solve number problems.
Third Space Learning often incorporates bar modelling into our online one-to-one tuition lessons. Paying close attention to each individual student,Third Space Learning identifies their learning gaps and moulds the programme to their needs.
