    (I) Concept of Area and Finding Area Using Non-Standard Unit

    For this activity, pupils will fnd the area o non-overlap pentomino pieces

    using 8x8 square grid paper.

    Materials :A set of complete 12 pentomino pieces for each group of players, 8x8

    square grid paper.

    Instructions:

    1. Students are divided into group of four.2. Each pair will e given a set of complete 12 pentomino pieces and a square grid

    paper.

    !12 pentomino pieces"

    %. Each player ta&es turns to place one pentomino piece on the 8x8 square grid and

    no pentomino piece is allowed to overlap another piece.'. (he first player who is not ale to place a pentomino piece is the loser.). (eacher chec&s on students* progress from time to time.+. After the activity, teacher will also call some students to present their finding to

    the class.8. An example to this solution is shown in the diagram elow,

    (II) Finding the area using the formula A = ! "

    3/22

    For this activity, pupils find the area cover by rubber bands in geoboard by counting the

    nails surrounded.

    Materials -eooard, ruerands

    Instructions:

    1. Students sit in groups of three.2. Each group will e provided with a geooard and some ruer ands.

    find the area.%. Students will ma&e a shape according to the length and readth given in the

    tale, as shown elow using the ruer and.Eg

    +. Students count the total numer of nails inside the area ordered y the ruer

    and, as shown elow,

    8. (he total numer of nail inside the area ordered y the ruer ands will e

    0. (eacher emphasis that the total numer of nails recorded is the area for that

    shape.1.Students transfer their findings into numerical form.11. (eacher stress that writing the unit is important and need to e given attention.

    (III) Compare masses of t&o o%'ect using standard units

    At the end of the lesson student will be able to compare the masses of two objects.

    Materials: ruits !apples, orange, papaya, pineapple etc", two weighing

    scales.

    Instruction:

    1. (eacher start the teaching activity y introduce the terms 3heavier than4 and

    3lighter than4 y demonstrate it y using two weighing scale measure twodifferent o5ect !apple and orange".

    2. After that, student will e seated in a group of four.#. Each group will e given ' orange, a papayas, # mangoes, ) apples, a pineapple

    and two weighing scale.%. (hey have to measure and record masses of two o5ects at the same time y

    using two weighing scales according to the tale.'. (hen they had to compare the masses of oth of the o5ect that they had found

    using the vocaulary heavier then or lighter and record it down in the tale elow.

    ' apples ' orange

    # mangoes A pineapple

    # apples and 2 orange A papayas

    2 apple and a papayas 2 orange

    ). After every group of student has finish measure and record the masses of the

    fruit, teacher will compare their results.+. 6f there have incorrect answer teacher will correct it.

    (I*) Conersion of unit of mass

    At the end of the lesson student will be able to convert Kilogram to gram and vice verse.

    Materials: $ig ag of sands !weigh of each ag 7 1g", eighing Scale.

    Instruction:

    1. Students will e wor&ing in group for this activity.2. (eacher start the activity y placing a ig ag of 1 g sand on the weighing

    scale.
