乘法转盘 = Roda Darab
这是一个乘法游戏：按“Pusing（转）”，两个转盘各停在一个数上，把两个数相乘，从三个答案里选出正确的积。一共五回合，答对一题得一分。
例子：转盘停在 125 和 8，积是 125 × 8 = 1 000。
注意：答错可以再试，想一想用哪一种乘法方法最快。
multiplication wheels = Roda Darab
This is a multiplication game. Press Pusing to spin; each wheel stops on a number. Multiply the two numbers and choose the correct product from three answers. There are five rounds, and each correct answer scores one point.
Example: if the wheels stop on 125 and 8, the product is 125 × 8 = 1 000.
Watch out: you can try again after a wrong answer; think about which method is quickest.

玩法 = cara bermain
每一回合先按“Pusing”，看两个转盘的数。用学过的方法算出两个数的积：乘 10、100 就补 0；乘一位数用竖式；乘两位数可以用竖式或格子法。选出答案后，答对就可以进入下一回合。
例子：转到 53 和 100 时，只要在 53 后面补两个 0，得 5 300。
注意：第一次就答对才得分，所以先估计再选。
how to play = cara bermain
In each round press Pusing and look at the two numbers. Use a method you have learnt to find the product: add zeros for × 10 or × 100, the column method for one digit, and the column or lattice method for two digits. Choose your answer; when it is right, go on to the next round.
Example: if the wheels show 53 and 100, just write two zeros after 53 to get 5 300.
Watch out: you score only if your first choice is right, so estimate before choosing.
