  • Elementary mathematics was part of the education system in most ancient civilisations, including Ancient Greece, the Roman empire, Vedic society and ancient Egypt.
    In most cases, a formal education was only available to male children with a sufficiently high status, wealth or caste.
    HISTORY
    • The key to teaching math so students internalize and transfer their knowledge is to make learning math personal.
    • No matter how many worksheets students complete, they will never make the connection between math concepts until it is concrete and relates to their personal environment.
    • Math needs to be real and not just a set of numbers or endless problems to calculate.
    • Personal math allows students to link concepts as whole and not a lot of independent ideas (or baseballs) with no connection.
  • The following techniques aid students transferring math concept knowledge to other math concepts for linking concepts
  • The following techniques aid students transferring math concept knowledge to other math concepts for linking concepts
    • Problem-Based Learning (PBL)
    • Interactive Math Tools
    • Using Manipulatives to Model Math Problems
    • Explain How to Solve Math Problems in Writing
    • Making Connections
  • Techniques that aid students to transfer math concept knowledge to other math concepts for linking concepts.
    Problem-Based Learning (PBL)
    The best strategy in PBL is the use of case studies which present students with real life problems that require applications of math to solve or find a solution. Students:
    determine what they know by identifying what is known, what needs to be find out, what they want to learn (KWL) based on a given case study scenario.
    develop a problem statement which contains steps for solving the problem and factors for determining successful completion.
  • Techniques that aid students to transfer math concept knowledge to other math concepts for linking concepts.
    Problem-Based Learning (PBL)
    The best strategy in PBL is the use of case studies which present students with real life problems that require applications of math to solve or find a solution. Students:
    gather information through online resources, surveys, interviews, observations, measurements, etc.
    develop possible solutions using concept maps, Venn diagrams, graphic organizers, etc.
    present a solution to the case study based on what was learned.
  • Techniques that aid students to transfer math concept knowledge to other math concepts for linking concepts.
    Interactive Math Tools
    Choose an interactive tool that requires students to use problem solving strategies that use formal operational skills and proportional reasoning.
    The best interactive math tools require students to solve problems by applying more than one math concept.
    Interactive math addresses the problem of engaging students through the use of virtual manipulatives to help them visualize math relationships. Virtual math learning environments allow students to apply logic and reasoning for problem solving.
  • Techniques that aid students to transfer math concept knowledge to other math concepts for linking concepts.
    Using Manipulatives to Model Math Problems
    Learning and understanding mathematics, at every level, requires student engagement.
    Students must be engaged in the learning process through practical applications of math.
    Whether the manipulatives are purchased in kits or created from available materials, this hands-on learning approach engages students’ minds as they use manipulatives to create models and representations to solve math problems.
  • Techniques that aid students to transfer math concept knowledge to other math concepts for linking concepts.
    Explain How to Solve Math Problems in Writing
    This technique involves students solving a problem and then writing a story describing how the problem was solved.
    Writing provides students with a creative method to think and internalize how they linked math concepts in real life problem solving situations.
    These student writings also provide teachers with an insight into a student’s true understanding of math that a dozen work sheets could never provide.
  • Techniques that aid students to transfer math concept knowledge to other math concepts for linking concepts.
    Making Connections
    When students are engaged in learning math that is personal to them, they are engaged in the learning process.
    Problem solving situations, case studies, and traditional math problems focused on students provide increased opportunities to internalize and make connections.
    Students like to participate and not watch demonstrations of how to solve problems; true understanding comes from hands-on, minds-on math.
  • EFFECTIVE MATHEMATICS TEACHING
    • Questioning
    • Encouragement
    • Modelling
    • Clarity
    • Expectations
    EFFECTIVE MATHEMATICS TEACHING
    • QUESTIONING
    Effective teachers ask more process questions (calling for explanations) and more product questions (calling for short answers.
    • ENCOURAGEMENT
    Effective teachers are more encouraging (e.g., providing reinforcement for questions and requests for help) and receptive to student input
    EFFECTIVE MATHEMATICS TEACHING
    • MODELLING
    Effective teachers exhibit more problem solving behavior and communicate the importance of problem solving.
    • CLARITY
    Effective teachers exercise more clarity (i.e., careful use of vocabulary and systematic explanations)
    EFFECTIVE MATHEMATICS TEACHING
    • EXPECTATIONS
    Set firm and appropriate expectations. High academic expectations are a major factor that differentiates effective schools from ineffective ones.
    EFFECTIVE MATHEMATICS TEACHING
  • TELLING TIME
  • Telling Time
    You can tell what time it is in several ways:
    the position of the sun in the sky,
    the length of shadows,
    the activities people are doing,
    and clocks and watches.
  • Telling Time
    Direct student's attention to the clock.
    How many big numbers are on the clock?
    Have students point to the hour hand.
    Tell them that when the hour hand moves from one number to the next, one hour has passed.
    Have students point to the minute hand.
    Tell them that when the minute hand moves from one tick mark to the next, one minute has passed.
  • Write the minutes to tell time.
    3:15
    9:05
    15 minutes past 3
    5 minutes after 9
  • Write the minutes to tell time.
    10:40
    04:30
    20 minutes before 11
    5 minutes after 4
  • Write the minutes to tell time.
    Combine visuals
    Equivalent answers
    With word problems and/or statements
    6:21
    21 minutes past 6
  • BASIC OPERATIONS
  • Basic Operations
    The four basic mathematical operations are:
    + Addition
    - Subtraction
    × Multiplication
    ÷ Division
  • Basic Operations
    ADDITION
    Adding two (or more) numbers means to find their sum (or total). 
    The symbol used for addition is '+'.
    8 - addend
    + 4 - addend
    12 - Sum
  • Basic Operations
    ADDITION
    For example, 5 + 10 = 15
    This is read as five plus ten is equal to fifteen or simply, five plus ten is fifteen.
    Find the sum of 9 and 8.
    Solution:
    9 + 8 = 17
  • Basic Operations
    SUBTRACTION
    Subtracting one number from another number is to find the difference between them. 
    The symbol used for subtraction is '–'. 
    This is known as the minus sign.
    We call the ‘total’ or result of subtraction as difference.
  • 9 - minuend
    - 4 - subtrahend
    5 - difference
  • Basic Operations
    SUBTRACTION
    For example, 17 – 8 = 9
    This is read as seventeen take away eight is equal to nine or
    seventeen take away eight is nine. 
    Also, we can say that 17 minus 8 is 9.
  • Basic Operations
    MULTIPLICATION
    Multiplication means times (or repeated addition). 
    The symbol used for multiplication is '×'.
    A product is the result of the multiplication of two (or more) numbers.
  • Basic Operations
    MULTIPLICATION
    For example, 7 × 2 = 14This is read as seven times two is equal to fourteen or simply, seven times two is fourteen.
    To multiply a large number with another number, we write the numbers vertically and generally multiply the larger number with the smaller number
  • 8 - multiplicand
    x 5 - multiplier
    40 - product
  • Basic Operations
    DIVISION
    Division 'undoes' multiplication and involves a number called the dividend being 'divided' by another number called the divisor.
    The symbol used for division is '÷‘.
    Clearly, 9 x 8 = 72
    Therefore, 72 ÷ 9 = 8
    And 72 ÷ 8 = 9
  • 8 - quotient
    Divisor - 6 48 - dividend
  • Basic Operations
    SUMMARY
    Adding two (or more) numbers means to find their sum (or total).
    Subtracting one number from another number is to find the difference between them.
    Multiplication means times (or repeated addition).  A product is the result of the multiplication of two (or more) numbers.
    Division 'undoes' multiplication.

    In fraction, it is written as ½ and is read as one half
    1 – numerator
    2 – denominator
  • FRACTIONS
  • PROBLEM SOLVING
  • Teach word problems by the following guidelines recommended by Blankenship and Lovitt (1976)
  • Guidelines in teaching Word Problems
    Teachers should identify and teach story problems by type, according to various characteristics (Examples: Extraneous information, verb tense, number and types of nouns).
    Make up several problems of each type in order to provide practice.
    A group of instruction technology should be outlined and used. It may be necessary to vary the technology according to the needs of each student; however, a systematic plan is essential
