### Teknik Menjawab Matematik

1. 1. TOPICS FOR MATHEMATICS UPSR1. Numbers and Operations - Add Subtract Multiply Divide2. Fractions Decimals Percentage3. Mixed Operation4. Average5. Money6. Shape and Space7. Measurement - Time Length Mass Volume of liquid8. Graph / Data handling
2. 2. NUMBERS AND OPERATIONS Basic skills in Mathematics. Pay careful attention to place value and digit value. Skills on rounding off numbers are important. Skills on addition and multiplication Skills on subtraction dan division will be tested inyour UPSR MT 015/2- Basic Skills MT 015/1 - Solving Problems (applications skills and critical thinking skills)
3. 3. FRACTIONS, DECIMALS AND PERCENTAGE These topics are related with one another. Concept is less than one ⅜ of the questions asked are related to the topics above. Fractions - on denominators Decimals - decimal points Percentage - X 100 % Usually asked on problem solving questions fractions multiply a whole number Look for key words in the questions and understandwhat is asked for. Practice on completing fractions and understandvocabulary related to the topics.
4. 4. MIXED OPERATIONS AND AVERAGE Has its own principles and formulas. Mixed Operation - BO DM AS For MT 015/2, you must show your workings clearly and make sure you are confident with your workings. Do notshow 2 methods and expect the teacher to choose foryou. Jumlah Jumlah Purata = Bilangan = Average - Bilangan Purata Jumlah = Purata × Bilangan Questions on Average for MT 015/1 are usually on how to find the total when the average is given. For finding the total : a. Multiply average with number of quantities. b. add all the number of quantities given. c. product (a.) take away with the total (b.) d. if asked for 2 equal amount- divide by 2
5. 5. MONEY Value for RM and sen. write sen in RM vice - versa. Operation involving conversion of value. Problem solving involving: 1. Tables 2. Incomplete bills 3. Income and Spending 4. Percentage, fractions 5. Average 6. Mixed Operations 7. Cost Price and Selling Price – Profit and Loss Bare in mind that questions on problem solving onMoney also involves combination of other topics andskills.
6. 6. SHAPE AND SPACE Must have sides or boundaries Shapes like rectangles, squares, triangles, circles and others. Combination of shapes and solids Know the characteristics of shapes and solids Recognize the sides of the shape or solids Use the formulas for finding: 1. perimeter - adding all outer sides 2. Area of - length x width/breadth Area of - base x height ÷ 2 3. Volume - length x width x height Questions on Problem Solving on this topic will alsoinclude fraction, percentage and money. Important: you must also know how to find the sides.
7. 7. MEASUREMENT TOPICS  Read the tools  Analyze the tools TIME  Conversion of units  24 hours system LENGHT  Fractions on time WEIGHT/MAS S  duration  Operation VOLUME OF LIQUIDS  Problem Solving  Difficult question that carries 3 marks
8. 8. GRAPHSInterpret dataAnalyze dataRead dataConstruct from dataQuestions on graph will be asked in MT 015/1
9. 9. TYPES OF QUESTIONS IN MT 015/1Mechanical QuestionsQuestions on Diagrams, Bills and TablesQuestions on situations/ Problem SolvingQuestions on number lines: Whole Numbers Decimals FractionsQuestions on graph
10. 10. STRATEGY IN SOLVING PROBLEMSUNDERSTANDPLANSOLVECHECK STEPSREAD THE QUESTIONWHAT IS GIVENWHAT IS ASKED FORHOW TO SOLVE ITSOLVE ITCHECK IT
11. 11. COMMUNICATION IN MATHEMATICSTypes of communication - language - information from diagrams - understanding from symbols and formulaeKey words example : After a discount of 30%, the total selling price of 4 similar T-shirts is RM 140. What is the cost price of a T-shirt? A RM42 C RM98 B RM50 D RM200Understand what the question is asking?Convert it to mathematical sentence/number sentence.
12. 12. HOW TO MANAGE INFORMATIONInformation from questions, diagrams and tables.Show or jot down informationCCTS information from questions given.Self Interaction: What is the meaning? Any similarities. What does it signify? Any other connection with other things in the question.
13. 13. Example: 4 cm Diagram 12 Diagram 12 shows a cuboid with a volume of 300 cm3 . A cube of sides 4 cm is cut from thecuboid. What is the volume, in cm³, of the portion that isleft? A 236 B 252 C 284 D 296
14. 14. 1. Previous knowledge:2. Reading: Key words: What is given? What is asked for?3.How to manage information given? Seen Hidden4.How to solve the problem?5. Checking
15. 15. TYPES OF QUESTIONS IN MATHEMATICS PAPER 2, 015/2QUESTIONS ON BASIC OPERATIONSQUESTIONS ON DIAGRAMS / TABLESQUESTIONS ON SIMPLE SITUATIONS
16. 16. 1 mark 2 marks 3 marksMarks given only Marks given to Division of marks:for correct workings and 1 markanswer. correct answer. •reading of tools •conversion of units/new valuesTOPICS TOPICS 1 mark • correct operationWhole numbers Mixed Operations usedBasic operations Average 1 mark FractionsFractions •Correct answer DecimalsDecimals TOPICS MoneyTime Shape and Space MeasurementsShape Time Shape and Space Percentage Money Percentage
17. 17. Technique Of Answering Mathematics Paper 2 Questions (015/2)1. Technique of constructing and copying tables If you are not able to remember your tables/how to convert units, write down the tables/units first before you start answering the questions.2. Technique of answering diagrams/tables For questions on diagrams/tables (esp. questions on perimeter, measurements tools etc.) it is best for you to write down the appropriate units or hidden information before you continue to solve the problem.
18. 18. Technique of Answering Mathematics Paper 2 (015/2)3. Technique of drawing diagrams or tables For questions on problem solving which do not show any diagrams or tables, it is better for you to understand the question by drawing diagrams or tables or jotting down the important notes.4. Important: Questions on problem solving must be solved systematically or follow the correct steps.
19. 19. Notes:a. All workings must be shown clearly. You may lose marks if you do not show the correct steps. Please do your work systematically.
20. 20. Note:b. Do not send booklet that is not answered. It is better for you to answer part of the question than leaving it blank. You may get some marks for the part that you have answered.
21. 21. Note:c. Use 2B pencil when answering all questions. Answers must be neat, clear and systematic. Your booklet must be clean. Do not draw or scribble anything that is not asked for.
