This is referred to as a spiral approach.**It is likely that a teacher will start this unit using the**sticks. This is followed by the use of base ten blocks. Finally, non-proportionate materials such as coins are used. In each of these lessons, the teacher is likely to introduce the following five notations in turn – place value chart, expanded notation, number in numerals, number in words and the tens and ones notation. The question is what is an appropriate sequence? Should the place value chart be used first? Or the expanded notation? Give your reasons. Place Value Chart Expanded Notation Words Numerals Tens and Ones Notation Primary Mathematics**ZoltanDienes**This lesson include perceptual variations. This is Dienes’ idea of multiple embodiment. The mathematical concept is constant while the materials used to embody it are varied.**Jerome Bruner**Bruner advised teachers to use the CPA Approach in teaching mathematics.**Richard Skemp**Skemp distinguished between instrumental understanding from relational understanding to encourage teachers to teach for conceptual understanding.**conceptual**skemp’s theory understanding BinaBangsa School, Semarang, Indonesia**Example 2**Division in Other Grade Levels**The Bar Model Method**de strookmodel Yeap Ban Har, Ph.D. Marshall Cavendish Institute Singapore banhar@sg.marshallcavendish.com**Beliefs**Interest Appreciation Confidence Perseverance Monitoring of one’s own thinking Self-regulation of learning Attitudes Metacognition Numerical calculation Algebraic manipulation Spatial visualization Data analysis Measurement Use of mathematical tools Estimation Mathematical Problem Solving Reasoning, communication & connections Thinking skills & heuristics Application & modelling Skills Processes Concepts Numerical Algebraic Geometrical Statistical Probabilistic Analytical Mathematics Curriculum Framework**visualization**Wellington Primary School**John had 1.5 m of copper wire. He cut some of the wire to**bend into the shape shown in the figure below. In the figure, there are 6 equilateral triangles and the length of XY is 19 cm. How much of the copper wire was left? 19 cm x 5 = 95 cm 150 cm – 95 cm = 105 cm**There was an interesting discussion on this problem. There**was an explanation that a + b + c = 19 cm. Then there was an assumption that a : b : c = 4 : 2 : 1 which was met with rebuttals such as there is no need to know a : b : c as well as the point that a : b : c can be determined by measuring or folding.**The Bar Model Method**de strookmodel Yeap Ban Har, Ph.D. Marshall Cavendish Institute Singapore banhar@sg.marshallcavendish.com**Ali has 3 sweets.**Billy has 5 sweets.

The teacher**asked the class to change this to another number to make the situation possible. We discussed when it is 3, 4 and 5 times. A student gave an incorrect solution for the second part. The teacher asked students to write a question for which this would be a correct solution.

We also saw how a problem can be modified to challenge learners.**School Assessment**women men
