Written by Minoli Almeida What is Singapore Math and why is it so popular in other countries? Is it true that this method makes math easily understood by kids? Find answers to all these questions and find out how Singapore Math works right here. What is Singapore Math? What folks the world over refer to as ‘Singapore Math’ is just ‘math’ to us here in Singapore. It is a special method of teaching math that was developed in 1982 for children from kindergarten through grade 6, as part of the national curriculum under the supervision of the Ministry of Education. Before this method was introduced here in Singapore, primary schools used mathematic textbooks from other countries. In 1981, the Curriculum Planning and Development Division (then Curriculum Development Institute of Singapore) began plans on the new curriculum. In 1982 the series of textbooks named ‘Primary Mathematics’ were distributed to schools nationwide. These textbooks were revised once in 1992, with more emphasis put on problem solving. Singapore Math’s popularity overseas The effects of the new curriculum were obvious in an international assessment conducted by the Trends International Mathematics and Science Society (TIMSS) done on 4th and 8th graders. This assessment ranked Singaporean students first in the years 1995, 1999 and 2003. That’s why mathematicians and educators in other countries started paying closer attention to Singapore Math, and textbooks such as Primary Mathematics. ‘Primary mathematics’ series of books were developed and distriuted to schools nation-wide. Photo source: www.singaporemath.com In 1998, Jeff and Dawn Thomas from Oregon, U.S.A. established a company named Singapore MathTM to distribute books to schools and homeschooling parents throughout the U.S. They did this after using the method with their own child. As Singapore Math became more popular, more schools in the U.S and in other countries such as the United Kingdom, Canada and Israel also started using it. As a result, many schools claimed there was a definite improvement in student test scores. How does Singapore Math work? Singapore Math focuses mainly on building fundamental math skills, rather than focusing on content. The Singapore math method takes a different approach to the methods taught in other countries. It teaches students to focus on a few key concepts in greater depth, using a three-step learning approach — concrete, pictorial and abstract. The key concepts are taught with the hope that children will master how these concepts work as well as why they work. The three-step learning approach This particular learning approach is based on the theories of American psychologist Jerome Bruner. He suggests that people learn by first handling real-life objects, then transition into understanding something pictorially and then symbolically. Children can be encouraged to learn mathematics by counting on an Abacus. So if you follow this process when teaching children, they will have a greater understanding of what they are learning, rather than just memorising facts. The first step of the three-step approach is the concrete step, where teachers use something kids can touch and feel like dice, blocks or colour pencils to show concepts such as addition and subtraction. The three-step approach teaches kids to progress gradually and enjoy math in the process. After this, kids can progress to the pictorial stage and strengthen their knowledge of the concepts they have learnt by using diagrams called ‘bar-models.’ A rectangular bar shape would represent numbers. This bar method can be used for subtraction, multiplication, division, fractions, ratios and decimals as well. (More on this later) So what ‘key concepts’ does the Singapore Math system teach? Let’s have a look… There are two key concepts that children learn in the Singapore Math system. Let’s explore these two concepts by solving simple problems. The part whole concept Through this concept, a child is taught to understand the concept of ‘parts’, and that the sum of these parts make the ‘whole’. Here’s a sample problem: “If Isabelle has 3 balls and Leanne has 2, how many balls do both have?” A child can draw a bar to represent the total, then divide it into a slightly larger portion and a smaller portion. Next, he will label the two rectangles with the numbers, and then simply add the two to achieve the result as follows: The part-whole method illustrated.

The comparison concept While the part whole concept uses one full bar to represent the whole, the comparison model uses two parallel bars. For instance, let’s solve this problem: “If Emily has 5 pencils and 3 erasers, how many more pencils does Emily have?” The problem can be solved as follows: The comparison method illustrated.Photo source: www.koobits.com The comparison method illustrated with pencils and erasers. Photo source: www.koobits.com The comparison concept can also be used for addition, subtraction, division and multiplication. Once children are comfortable with using these two concepts to solve basic math problems, they can use them to solve problems involving fractions, ratios and decimals as well. What about your child?

Singapore teaches maths better than most countries including the UK, according to international rankings for secondary pupils. The difference starts at an early age. There are many reasons but one key factor is its step-by-step approach that can be used at home or in the classroom. Young children are happy playing with blocks or drawing pictures. But they can find number symbols, like 5 + 2 = 7, mystifying. So the Singapore method begins by allowing children to start learning about maths by playing with real objects, blocks or cut-out pictures. They build confidence with the basic ideas of adding and taking away. There is then a second stage of drawing pictures representing the objects. And only later do they gradually start to add numbers to their drawings. Maths without symbols? Straight to the symbolic - a leap too far for many children? In education systems in the UK, pre-school children are often introduced to maths and to number symbols at the same time. For instance through brightly-coloured counting books which show a picture of an apple - or a kite or a butterfly - next to a '1'. Two new things next to a '2'. Three new things next to a '3'. Culminating in a loose group of ten things next to a '10'. But number symbols like 5 or 10 as well as symbols like + or - are often difficult for children to understand. And if they are introduced too quickly, there is a risk that young children will struggle and from then on never fully recover their confidence in maths. Failing repeated tests on symbolic sums at school only deepens their anxiety and they soon learn that maths is not for them. The Singapore method illustrated in more detail below goes more gradually - from handling "concrete" things, to drawing one-to-one "pictorial" iconic representations of them, to eventually understanding and using the mysterious "abstract" symbols with confidence. 1. Lining up objects in a row Children start by counting familiar things using blocks or cut-out pictures they can physically line up in a row. For instance counting pieces of fruit, their own ages, or people in the room. With one block or cut-out picture for each orange, or year, or person. They can learn most basic maths concepts with these objects. For instance add objects to the row, or take them away, to understand adding and subtraction. Or split a row in the middle to understand halving. 2. Drawing boxes around pictures Then children start to draw pictures on paper of the things they are counting, with a box around each picture. So there's one box for each thing they are counting. Over time they drop the pictures and just draw the boxes. 3. Labelling the boxes In the 1960s American psychologist Jerome Bruner (above) put forward a theory that people learn in three basic stages: by handling real objects, through pictures, and through symbols. Bruner said symbols are "clearly the most mysterious of the three." In the 1980s Singapore developed its model method based on Bruner's theory. Gradually, once they are confident with drawing boxes to count objects, children start to write the number of boxes as a figure above the drawing. Eventually they no longer need to draw all the boxes. They just draw one long box or bar and label it with the number. This step away from one-to-one representations to symbols is crucial and it may take a year or more for some children to become confident with it. But the benefits later on are worth it. The Singapore Model Method This model of numbers as labelled bars is known as the Singapore model, and it's a tool children can use to understand almost any concept in maths, including multiplication and division and even algebra. Professor Lianghuo Fan, former editor-in-chief of Singapore's maths textbooks, has researched the reasons for Singapore's success in maths. As he puts it: "People have different views about the reasons for Singapore students' performance, but one thing that is universally agreed is that the Singapore model method is key." You can see examples of different stages of the model in this slideshow: Imagine you have five oranges and three apples, how many more oranges than apples? At first children model the problem with physical objects they can move around: like these cut-out pictures. After a few months they start to draw pictures of the problem to help them think about it. Over time children drop the pictures and just draw boxes. Then they start adding numbers as labels. Once children are confident with the meaning of the number symbol they no longer need to draw all the boxes. However they know they can always draw the boxes in again if they need to convince themselves. How much change if you pay for a £30 shirt with a £50 note? The model can be used to help visualise almost any maths problem. Three people want to split a restaurant bill of £76. How much for a couple who want to pay together? The model helps break the problem down. First divide £76 by 3. Then times the answer by 2. In a year group there are 50 children. There are 10 fewer girls than boys. How many boys? The model can help visualise the unknown quantity. You can see that x + x - 10 = 50. If you add the 10 you get x + x = 60. So x = 30. 10 top tips for trying the Singapore model method with your kids: Count things with objects Try counting familiar things together like the number of people in the room, kids' ages, or goals in football matches, using concrete objects like counters, buttons or small stones, lining them up one by one. If nothing's to hand use fingers. Get some interlocking cubes Interlocking cubes are great and can be bought for a few pounds, or your child's nursery or school may be able to lend you some. Try carrying round a few to count things when you're out and about. They are also good for kids to play with to keep them occupied. Use cut-out pictures Draw pictures on paper and cut them out to use as counters with your kids. Or print out our handy Singapore model cut-out pictures and use them at home with your kids, to count people, ages, goals, coins or fruit. Do basic arithmetic with objects You can talk about most basic arithmetic using concrete objects, adding objects to the line, taking them away. 'Multiply' literally means 'many layers' and you can show times tables by layering rows one on top of the other. Use interactive blocks If you have an iphone or Android mobile why not try BBC Skillswise's interactive blocks: text SKILLSWISE to 81010 or if you are reading this on your mobile device preview the interactive times tables blocks. Please note texts to the BBC cost 12-15p, interactive not compatible with all phones. Draw pictures Give kids pens and paper to draw things they count, lined up in a row. Encourage them to draw boxes around the pictures. The fact they have drawn the pictures gives them a sense of ownership and means they'll probably be more confident in talking about them. Don't rush to use figures Hold off from using number symbols until your child is really confident with concrete and pictorial representations and can make the link. So they will always have a ready way of picturing what the symbol means as a fall-back. Start with figures 1 to 9 When you do start using symbols to label drawn boxes, stick to 1 to 9 at first to build confidence, so one figure relates to one quantity. The leap from the figure 9 to the figure 10 involves concepts of place value and zero which can take time to understand. Brush up your own maths to help your kids Most of us feel a bit rusty with maths, especially the new methods used in schools these days. Why not be a learning role model to your kids by joining a local maths class for adults? You can find out about free local courses from the National Careers Service as well as family learning centres near you on the Sure Start website. Or brush up your maths skills online with maths websites for adults like BBC Skillswise. Go slowly to build confidence It takes time for children to get really confident with the basics. The Singapore curriculum actually covers less than the UK national curriculum in the first few years, instead taking more time to build confidence in the basics. But this pays off in spades later on. TOP TIP: Be positive Above all be positive. Enjoy playing with and counting objects together, celebrate effort and praise often. Real learning involves making lots of mistakes. Try to see mistakes as positive things that highlight deeper misunderstandings. Why did I think that? Kids have years of maths lessons ahead of them and every ounce of self-confidence helps them to succeed. Boosting children's understanding with objects and pictures is key.
