Unit 10
Relaks Minda
Permainan «Siapa Pemenang?»
Cabut satu kad soalan. Cari petak yang betul pada papan permainan dan letak cip.
Dapat 3 cip sebaris (mendatar, menegak atau serong)? Kamu menang!
动动脑 = relaks minda；题卡 = kad soalan；筹码 = cip
这一课玩“谁是赢家”游戏，复习整个单元。抽一张题卡，按卡上的特征（几条边、几个顶点、是不是棱柱、有几条对称轴），在棋盘上找出对的图形，放一个筹码。三个筹码连成一线（横、竖、斜）就赢了。
例子：卡上写“8 条边”，就把筹码放在八边形上。
注意：放错了就失去这一轮。
mind relax = relaks minda; question card = kad soalan; counter = cip
This lesson is the game “Who Is the Winner?” to revise the whole unit. Draw a question card, use its clue (number of sides or vertices, prism or not, lines of symmetry) to find the right shape on the board, and place a counter there. Three counters in a line, across, down or diagonal, wins.
Example: if the card says “8 sides”, put your counter on the octagon.
Watch out: a wrong answer means you lose that turn.
Papan permainan
Kenali papan
Ada bentuk 3D dan poligon sekata
3 cip sebaris secara serong → menang!
认识棋盘 = kenali papan
棋盘上有立体图形（正方体、圆锥、金字塔、三角棱柱、圆柱、长方体），也有平面图形（五边形、六边形、七边形、八边形、平行四边形、长方形）。图中三个红色筹码斜着连成一线，这位玩家就赢了。
例子：同一横排连续三格都放了筹码，也算赢。
注意：一格只能放一个筹码。
getting to know the board = kenali papan
The board has solid shapes (cube, cone, pyramid, triangular prism, cylinder, cuboid) and flat shapes (pentagon, hexagon, heptagon, octagon, parallelogram, rectangle). In the picture, three red counters form a diagonal line, so that player wins.
Example: three counters next to each other in one row also win.
Watch out: only one counter can go on each square.
Kad 1
🃏 Saya ada 8 sisi.
Petak manakah?
第 1 张卡：8 条边 = kad 1: 8 sisi
有 8 条边的正多边形是八边形 oktagon，像“停”字交通牌。七边形 heptagon 有 7 条，六边形 heksagon 有 6 条，看起来都很像，一定要一条一条数。
例子：卡上写“6 条边”，就选六边形。
注意：边越多越像圆，数的时候用手指点着数。
card 1: 8 sides = kad 1: 8 sisi
The regular polygon with 8 sides is the octagon, like a STOP sign. The heptagon has 7 sides and the hexagon 6, and they all look alike, so count each side one by one.
Example: if a card says “6 sides”, choose the hexagon.
Watch out: the more sides a shape has, the rounder it looks, so point at each side as you count.
Kad 2
🃏 Saya prisma. Saya ada 5 permukaan rata.
Petak manakah?
第 2 张卡：棱柱、5 个面 = kad 2: prisma, 5 permukaan
三角棱柱有 2 个三角形底面加 3 个长方形侧面，一共 5 个面，是棱柱。金字塔也有 5 个面（1 个正方形 + 4 个三角形），但它只有一个底面、上面是尖的，不是棱柱。长方体是棱柱，但有 6 个面。
例子：卡上写“6 个面、全部正方形”→ 正方体。
注意：卡上有两个线索，两个都要符合。
card 2: prism with 5 faces = kad 2: prisma, 5 permukaan
A triangular prism has 2 triangle bases and 3 rectangle sides, 5 faces in all, and it is a prism. A pyramid also has 5 faces (1 square + 4 triangles), but it has only one base and a pointed top, so it is not a prism. A cuboid is a prism but has 6 faces.
Example: a card saying “6 faces, all squares” means the cube.
Watch out: the card gives two clues, and both must fit.
Kad 3
🃏 Saya tiada paksi simetri.
Petak manakah?
第 3 张卡：没有对称轴 = kad 3: tiada paksi simetri
平行四边形不管怎样对折，总有角露出来，所以没有对称轴。长方形有 2 条（横和竖），正五边形有 5 条。只有平行四边形是 0 条。
例子：L 形也没有对称轴。
注意：长方形的对角线不是对称轴，但它的横线、竖线是。
card 3: no line of symmetry = kad 3: tiada paksi simetri
However a parallelogram is folded, a corner always sticks out, so it has no line of symmetry. The rectangle has 2 (flat and upright) and the regular pentagon has 5. Only the parallelogram has 0.
Example: an L shape has no line of symmetry either.
Watch out: a rectangle's diagonals are not lines of symmetry, but its flat and upright lines are.
Pusingan pantas
Empat kad, empat petak
快速回合 = pusingan pantas
不是棱柱、只有 1 个顶点 → 圆锥（尖尖的顶）。有 6 条对称轴 → 正六边形（对称轴数 = 边数）。12 条棱、所有面都是正方形 → 正方体。7 个顶点的正多边形 → 七边形 heptagon。
例子：“0 个顶点、没有平面”→ 球体。
注意：圆锥有顶点但有曲面，所以不是棱柱。
speed round = pusingan pantas
Not a prism with only 1 vertex: the cone, with its pointed tip. 6 lines of symmetry: the regular hexagon, since lines equal sides. 12 edges with all faces square: the cube. A regular polygon with 7 vertices: the heptagon.
Example: “0 vertices and no flat face” means the sphere.
Watch out: a cone has a vertex but also a curved surface, so it is not a prism.
Kad emas
🃏 Saya ada 8 bucu. Tapak saya segi empat tepat yang panjang.
Letak cip terakhir!
金卡 = kad emas
8 个顶点的有正方体和长方体；金字塔只有 5 个。再看第二个线索：底面是长长的长方形。正方体的面全是正方形，不符合；长方体有长方形的面，符合。答案是长方体，放下最后一个筹码，连成三格就赢了！
例子：鞋盒、砖块都是长方体。
注意：最后一题也要把每个线索都核对一次。
golden card = kad emas
Both the cube and the cuboid have 8 vertices, while the pyramid has only 5. The second clue says the base is a long rectangle: the cube's faces are all squares, so it does not fit, but the cuboid has rectangle faces, so it does. The answer is the cuboid; place the last counter and complete the line to win!
Example: shoe boxes and bricks are cuboids.
Watch out: even on the last card, check every clue once more.
Ringkasan
Syabas!
kad soalan → cari ciri-ciri → letak cip
Prisma: 2 tapak sama dan semua permukaan rata. Poligon sekata: sisi sama panjang, sisi = bucu = paksi simetri. Segi empat selari tiada paksi simetri. Teruskan ke latihan untuk menguji diri!
