Inspire MathsThe Singapore Approach

Why Singapore?TIMSS The Trends in International Mathematics and Science StudyThe TIMSS achievement scale has a centre point of 500 and a standard deviation of 100. It is scaled to remain constant from assessment to assessment, allowing comparison over time.

The highest performing countries were those in the Asian Pacific Rim (four such countries for TIMSS 2007 and five in 2011). In Europe, only Northern Ireland significantly outscored England in mathematics at this age in 2011.

What is Inspire Maths?Inspire Maths provides a highly scaffolded learning framework with problem solving at its heart. It is built on a focused, coherent and cumulative spiral curriculum that continuously builds and consolidates knowledge to reach deep understanding. The programme encourages extensive practice to develop fluency and mastery, so that every child-across all abilities can succeed at mathematics.

Inspire MathsProblem solving curriculum

Emphasis on the development of intellectual competence such as the ability to visualise

Emphasis on conceptual understanding (representing concepts through objects and pictures, making connections between different representations)

Systematic development of skills and concepts - the spiral approach.

Emphasis on the C-P-A approach (concrete-pictorial-abstract)Show me 3

3 is abstract it is a concept.

A representation of 3 can be shown i.e. counters, fingers, numerals

Bruners forms of representationsStudents learn a new skill by using concrete materials, reinforcement is achieved by going back and forth between the representations.

Concrete Enactive internalised action.

Pictorial Iconic this can also be sensory imagery.

Abstract Symbolic arbitrary symbols (words, numerals)C-P-AChildren are expected to use and understand numbers, which are abstract concepts. Many children struggle with this and so their first experience of mathematics is confusing, leaving them with no solid foundation to build on for later learning. The CPA approach helps children achieve secure number sense what numbers really represent and how to use them mathematically. This is done through a series of carefully structured representations first using physical objects (concrete), then diagrams or pictures (pictorial), and ultimately using representations such as numerals (abstract).

Fluency and MasteryThe National Curriculum for mathematics aims to ensure all pupils:

become fluent in the fundamentals of mathematics, including through varied and frequent practice with increasingly complex problems over time, so that pupils develop conceptual understanding and are able to recall and apply their knowledge rapidly and accurately.

reason mathematically by following a line of enquiry, conjecturing relationships and generalisations, and developing an argument, or proof using mathematical language.

can solve problems by applying their mathematics to a variety of routine and non-routine problems with increasing sophistication, including breaking down problems into a series of simpler steps and persevering in seeking solutions.

Fluency and MasteryWhen children have achieved mastery in a particular area of mathematics they:

Are fluent in the facts and proceduresCan transform these facts, make connections and transfer their understanding to unfamiliar situations applying a higher level of mathematics and thinking.

Blobs and links in conceptual understandingConceptual UnderstandingBlobs= items of knowledgeMore links = conceptual understanding.Networks, discussion and practical work help form these links.Valsa KoshyHeuristics for Problem SolvingHeuristics refers to the different strategies that children can adopt to solve unfamiliar or non-routine problems.

Bar modellingPattern spottingUsing diagramsMaking conjectures, estimating (guess and check)Bar ModellingThe bar model is a step-by-step method that helps children to understand and extract the information within a calculation or word problem.

By drawing a bar model, children translate a calculation or word problem into a picture. The approach helps children process information given in the problem, visualise the structure, make connections and solve the problem.Why models?To help pupils to process the information in the question. (Read)

Make sense of the question or problem. (Think and Plan)

Just one of the ways to comprehend the problem & from the models, pupils will be able to work out the solution.Bar ModellingDifferent types of models

Part- whole model for multiplication and divisionThe following part-whole model represents a whole divided into 3 equal parts:

WholepartThe model illustrates the concepts of multiplication as:

One partxNumber of parts=Whole

222Models for multiplication and divisionJerry has 30 marbles. Tom has 4 times as many marbles as Jerry. How many marbles do they have altogether?

Jerry and Tom have ____ marbles altogether.?30JerryTom

Multiplicative Comparison ModelsOne quantity is a multiple of the other, e.g.

Larger quantity

Smaller quantityThe larger quantity is 3 times as much as the smaller quantity, and the smaller quantity is equal to 1/3 of the larger quantity.The difference between two numbers is 516.

If the larger number is 4 times the smaller number, find the sum of the two numbers.

516?/ 3= 172172172 x 5 = 860? = 860Ratio ModelThe following part-whole model shows a whole divided into 3 parts A, B and C in the ratio 2:3:4.WholePart APart BPart CThe following comparison model shows three quantities A, B and C which are in ratio 2:3:4.ABCThe ratio 2:3:4 means 2 units to 3 units to 4 unitsThe ratio of the number of Katies marbles to Emmas marbles is 4:5. Katie is given 12 more marbles.

Katie now has twice as many marbles as Emma. How many marbles did Katie have to begin with?

Katie had ____ marbles to begin with.

The ratio of Katies marbles to Emmas marbles is 4:5.Katie is given 12 more marbles and now has twice as many marbles as Emma. If Emma has 5 parts then Katie now has 10 parts meaning 6 are added to her original 4 parts.12 is the difference so 12/6 =2. Each part has the value of 2.Therefore 2+2+2+2=8. Katie had 8 marbles to begin with.KE?Double E =10 parts12/6=22222222222? = 8THIS IS A YEAR 6 LEVEL QUESTION!Change/Transforming ModelThis type of model can be used to solve complex problems.

The parts can be transformed into smaller units.

This type of model is useful for tackling problems which involve before-and-after situations.A shop keeper sold 1/3 of his balloons in the afternoon and 2/5 of the remainder in the evening.

If he had 150 balloons left, find the number of balloons he had at first.

He had ____ balloons at first.
