Literacy and Numeracy Statement Blueprint Implementation Paper DEECD 2009 Common Numeracy Situations in Everyday Life. Activity A look at some time in a normal day eg: List the mathematical decisions you made from the time you woke up this morning until about 9. 30? eg: List the mathematical decisions you might be making while in a car on the way to work or school this morning eg: List mathematical decisions you made in your lunch hour An activity for maths coordinators for professional learning for teachers; and an activity to use with students This module: Explicit Instruction: – Thinking and Working Mathematically using the Multi- Modal Think Board – Differentiation using the Multi- Modal Think Board – Using questions to differentiate tasks within mathematical modes – An Instruction Model with differentiation in mind Differentiating by: • Asking frequent, targeted, rigorous questions of students as they demonstrate mastery • Planning , working, assessing and reflecting in different mathematical modes • Working in different ways within a given mode • Using tasks that are open question based 5 The Mathematical Modes [The Singapore Multi-modal Think Board] 6 Thinking/Working Mathematically: A Think-Board [Multi-Model] to Teach Mathematics Using Multi-Modal Think-Board to Teach Mathematics Khoon Yoong Wong, Mathematics and Education Academic Group , National Institute of Education, Nanyang Technological University, Singapore, July 2004 e 5 Story- apply Numbercalculate e 5 Wordcommunicate Thinking/Working Mathematically e 5 Real Thing- do [eg: manipulative materials] e 5 Symbolmanipulate [algebra] Diagram- visualise Group Work in Mathematics: Whole group- small group – whole group Pairs is the most effective way to work in groups in mathematical contexts. (Students also need to be given the opportunity to work individually and practise being able to work individually). 8 Using the Multi-Modal Think Board Topic - Measurement and Subtraction Real Thing – do [Level 1 - 5] What might students ‘do’ [action] to calculate the difference in height between 2 people? Real Thing – do [Level 5 -6] For two ladders - ladder [a] 410 cm in length and ladder [b] 420 cm in length Ladders [a] and [b] are leaning against a wall. They touch the wall 400 cm above the ground. What is the difference in the distance between the foot of each of the ladders and the wall? Working/Thinking Mathematically Using Multi-modal Think Boards Khoon Yoong Wong 2004 Real Thing- Do – the use of concrete manipulatives – principle- learning by doing: I hear I forget; I see and I remember; I do and I understand [Piaget, Bruner] – grounding mathematical ideas in concrete situations helps develop mental models that provide meaning to abstract symbols , hence reducing the chance of anxiety phobia towards mathematics – without sufficient practical experience students have been found to lack numerical sense of measures about real objects and hence cannot determine whether their answers are reasonable or not in the real world Working/Thinking Mathematically Using Multi-modal Think Boards Khoon Yoong Wong 2004 Real Thing- Do [continued] – the transition from practical activities to formal abstraction, however, is not easy [Johnson 1989] – poorly designed manipulatives or improper use can hinder rather than facilitate conceptual development – ‘virtual manipulative’ – electronic technologies to support effective mathematics teaching Using the Multi-Modal Think Board * [Level 2 - 4] Calculate the difference in number, between two groups of objects. One group of 39 and the other 17. *[Level 3 - 5] Calculate the difference between 2. 48 m and 11. 48 m Symbol – manipulate – whole - part concept comparison [ compare collections when one collection is larger than another and with like and unlike objects] – change concepts [ increase or increment problems and decrease or deficit – manipulate the equation [‘milk the equation for all it’s problems] worth’] Story – apply Write problems with an authentic context using the equations that result Using the Multi-Modal Think Board Symbol Mode- manipulate Real - apply * 12 + 5 = 17 * 17 + 39 = 56 • 7 x 6 = 42 *480 ÷ 20 = 24 1. Rewrite the equations in as many ways as you can using only the numbers [values] provided. One of the numbers needs to be represented as an ‘unknown’ [variable] in each equation you write. 2. Write word problems (which have an authentic context) for some of the equations The Change Concept Try these for example – and there are more: 1. 39 + 17 = ( increase, result unknown) 39 2. 17 + = 56 ( increase, change unknown) 17 3. + 17 = 56 ( increase, start unknown) 4. 56 - 17 = = ( decrease, result unknown) 5. - 39 = 17 ( decrease, start unknown) 17 ? 56 ? ? 17 56 f 56 17 ? ? 39 17 Using the Multi-Modal Think Board Topic - Measurement and Division 86 220 m of rope was divided into 6 equal lengths to be sold. How much rope was in each of the lengths? If 2/3 of the rope lengths were damaged in a fire how many metres of rope were not damaged? Symbolic – manipulate Syntactic- what do I need to know to work this out with a calculator? ; division operation; fraction as an operator… Diagram- visualise- How might we demonstrate this problem in a diagram? Using the Multi-Modal Think Board Khoon Yoong Wong 2004 Diagram- Visualise Key word: represent • pictures • diagrams • graphs • charts • figures • illustrations • come in varying degrees of abstraction eg: a picture of several apples versus several dots • can be a pictorial summary of work done in ‘real thing ‘ mode • visual imagery ‘in the mind’s eye’ Using the Multi-Modal Think Board Topic – Division of fractions 6 ÷ ½ = 6½ = ¼ Diagram – visualise Story - application Using the Multi-Modal Think Board Topic – Fractions One hundred and eighty people attended a school function. If 1/3 of them were students how many people were not students? Number- Calculate Essential basic skills Processes Algorithms ‘working out’ Strategies 1/3 students Diagram - visualise 60 60 180 people 60 180 ÷ 3 = 60 One third = 60 Using Multi-Modal Think Boards Khoon Yoong Wong 2004 Word – Communication – words are essential for communicating mathematical ideas and thinking about them – as a mode of representation, it also includes phrases and sentences – as students often confuse the meaning of the same work when used in everyday situations and in mathematics – more acute when students learn mathematics in a foreign language – teachers should say mathematical terms precisely and consistently eg: x² is ‘x to the power of 2’ and not ‘x two’ Thinking and working mathematically • 6 modes for thinking and working mathematically • Instruction in all modes regularly, consistently- ie: where appropriate • Explicit instruction using closed questions • Tasks design - using open questions • Differentiation though using open questions Using the Multi-Modal Think Board Topic- multiplication [Level 4 - 5] A closed question Peter planted tomatoes seedlings in 35 rows with 20 in each row. If each plant produced [an average of] 43 tomatoes, what was the total crop? Pairs/draw/discuss In what ways might you represent this problem using a ‘diagram’ ? Opening up the question/task If Peter planted 375 tomatoes in rows and each plant produced 43 [on average] tomatoes, what might the planting in the rows look like? How many tomatoes did he have to sell? If students were asked to represent this problem using manipulative materials/contexts what might that involve? 2 Differentiation- calculate in different ways 0 0 6 del 45 x 25 = 1 7 x x 3 1 0 8 8 9 1 3 Lattice method 2 4 2 25 800 200 4 5 2 800 100 900 5 200 25 225 1 125 x 45 100 25 [40 x 20]+[40 x 5]+[5 x 20]=1 125 Using the Multi-Modal Think Board Topic- [might be? ] A closed task [Level 5] Round off 1. 29 to the nearest tenth In what ways might you represent this problem using a ‘diagram’ ? Pairs/draw/discuss Opening up the question/task [Level 5] What numbers when rounded off become 1. 3? What modes could you ask students to use to model / demonstrate understanding here? Using the Multi-Modal Think Board Topic – [might be ? ] del Closed context/task [Level 5] 0. 7 x 5 = Open task could be: [Level 5] The product of two numbers is 3. 5. What might be the two numbers be? Pairs - What are activities you could ask students to do in each of the modes for this problem? Diagram - visualise Number - calculate Story - apply Real Thing - do Symbol - manipulate Word - communicate Using a Multi- Modal Think Board del Topic – [might be ? ] Closed context/task [Level 6] Circle the number which is closest to 5. 4 5. 364 5. 46 5 5. 6 5. 453 Open task Word – communicate One of your friends ask you to explain the best way to decide which number is closest to 5. 4. How would you explain how to work out which number is closest to 5. 4? Using the Multi – Modal Think Board Content specific mathematics through questions/tasks Which fraction is smaller? 3 4 or 4 5 A corresponding open question/task is: Level 5 4 ? What are some fractions smaller than 5 Discuss – in pairs, work through the 6 modes. How might this task be addressed using each of the modes? Discuss Peter Sullivan 2003 Addition of Fractions Closed question 1 7 + 3 4 ? = 12 [Level 5. 6] Open task Progressively remove numbers replacing them with blanks gets us to a task like this 1 1 + ? ? = ? ? 27 A Balanced Mathematical Program Charles Lovitt A balanced mathematics program: Will meet individual needs of students AND Ensure students are working mathematically What do we mean by ‘working mathematically’? [Turn and talk] A Balanced Mathematics Program Charles Lovitt Working mathematically simultaneously involves: – essential skills practice AND (of equal importance) – thinking, reasoning and communication (Dimension of Structure) AND – meeting the demand of huge mixed ability in any given group- [potentially a 7 year spread in any class] Using the Multi - Modal Think Board Division of a decimal by an integer 0. 4 ÷ 2 = [zero point four divided by two] Task [a] and [c] – most students no difficulty Task [d] to [f] – more difficult When the task is changed to 0. 4 ÷ 0. 2 = even [a] and [b] become difficult and most students would not be able to complete Using Multi-Modal Think-Board to Teach Mathematics Khoon Yoong Wong • [a] Read this aloud - word • [b] calculate its value [not with a calculator] - number • [c] draw a diagram to illustrate the operation - diagram • [d] demonstrate the operation using real objects - real thing • [e] write a story or word problem that can be solved using this operation – story • [f] extend this operation to algebra – symbol - symbol Think- Board Use for: • planning • instruction • reflection • assessment An Instruction Model [one of many…] Andrew Fuller- The Get It!

Ask for another answer. Ask for a better word. Ask for evidence. Ask students to integrate a related skill. Ask students to apply the same skill in a new setting.
