由小到大 = tertib menaik；由大到小 = tertib menurun 排列时先找出最小的数目，再找下一个比较小的，一直排到最大，就是 tertib menaik；反过来从最大排到最小，就是 tertib menurun。 例子：四个数都是四位数，先比千位：4 985 的千位是 4，其余三个是 5，所以 4 985 最小；再比 5 062、5 206、5 260 的百位，0 比 2 小，所以 5 062 第二；5 206 和 5 260 百位相同，再比十位，0 比 6 小。 注意：4 985 的数字 9、8 看起来很大，但它的千位最小，所以它还是最小的数。

smallest to greatest = tertib menaik, greatest to smallest = tertib menurun To order numbers, find the smallest, then the next smallest, and so on up to the greatest; that is tertib menaik. Going from the greatest down to the smallest is tertib menurun. Example: all four numbers have four digits, so compare the thousands first: 4 985 has 4 thousands and the others have 5, so 4 985 is smallest. For 5 062, 5 206 and 5 260 compare the hundreds: 0 is less than 2, so 5 062 is next. 5 206 and 5 260 have the same hundreds, so compare the tens: 0 is less than 6. Watch out: 4 985 has big digits 9 and 8, but its thousands digit is the smallest, so it is still the smallest number.

由小到大 = tertib menaik 这一题要你选出从小排到大的一组。先比较三个数目的大小，找出最小的，看看哪一组是从它开始、一个比一个大。 例子：2 140、2 410、2 401 → 由小到大是 2 140、2 401、2 410。 注意：三个数目的千位都一样，要比百位和十位。

smallest to greatest = tertib menaik Choose the list that goes from smallest to greatest. Compare the three numbers, find the smallest, and see which list starts with it and gets bigger each time. Example: 2 140, 2 410, 2 401 → smallest to greatest is 2 140, 2 401, 2 410. Watch out: the thousands are all the same, so compare the hundreds and tens.

递增数数 = bilang menaik 按 1 数（satu-satu）个位每次加 1；按 10 数（sepuluh-sepuluh）十位每次加 1；按 100 数（seratus-seratus）百位每次加 1；按 1 000 数（seribu-seribu）千位每次加 1。 例子：从 5 206 按 10 数：5 216、5 226、5 236。 注意：数到 9 以后要进位，例如 5 296 再加 10 是 5 306。

count up = bilang menaik Counting in ones (satu-satu), the ones digit goes up by 1; in tens (sepuluh-sepuluh), the tens digit goes up by 1; in hundreds (seratus-seratus), the hundreds digit goes up; in thousands (seribu-seribu), the thousands digit goes up. Example: counting in tens from 5 206: 5 216, 5 226, 5 236. Watch out: after 9 you must regroup, for example 5 296 plus 10 is 5 306.

递减数数 = bilang menurun；递增数数 = bilang menaik 按 5 递减（menurun lima-lima）就是每次减 5；按 6 递增（menaik enam-enam）就是每次加 6；按 2 递减（menurun dua-dua）就是每次减 2。不熟练的时候，可以在数线上一步一步跳，每跳一次就写下新的数目。 例子：从 5 318 按 2 递减：5 316、5 314、5 312。 注意：menaik 是越来越大，menurun 是越来越小；减的时候个位不够要向十位借。

count down = bilang menurun, count up = bilang menaik Counting down in fives (menurun lima-lima) subtracts 5 each time; counting up in sixes (menaik enam-enam) adds 6; counting down in twos (menurun dua-dua) subtracts 2. You can jump step by step on a number line. Example: counting down in twos from 5 318: 5 316, 5 314, 5 312. Watch out: menaik means getting bigger; menurun means getting smaller. When subtracting, borrow from the tens if the ones are not enough.

按 4 数 = bilang empat-empat；按 8 数 = bilang lapan-lapan 按 2 数时，每跳两步就等于跳了一次 4；每跳四步就等于跳了一次 8。所以按 2、按 4、按 8 数出来的数，有一些是重叠的。同样，按 3 跳两步等于按 6 跳一步，按 3 跳三步等于按 9 跳一步。 例子：从 1 460 按 4 数：1 464、1 468、1 472；按 8 数：1 468、1 476，都是按 4 数时隔一个的数。 注意：按 8 数的每一个数也会出现在按 4 数里，但按 4 数的数不一定出现在按 8 数里。

count in fours = bilang empat-empat, count in eights = bilang lapan-lapan When you count in twos, every two jumps make one jump of 4, and every four jumps make one jump of 8. So counting in 2s, 4s and 8s lands on some of the same numbers. In the same way, two jumps of 3 make one jump of 6, and three jumps of 3 make one jump of 9. Example: counting in fours from 1 460: 1 464, 1 468, 1 472; counting in eights: 1 468, 1 476, which skips every other number of the fours. Watch out: every number you reach counting in eights also appears when counting in fours, but not every fours number appears in the eights.

由大到小 = tertib menurun 四个数目的千位都是 5，所以比较百位：百位最大的排第一。百位一样的，再比十位。依次点选字卡。 例子：3 071、3 710、3 107 → 由大到小 3 710、3 107、3 071。 注意：5 096 和 5 069 很像，它们的百位都是 0，要再比十位：9 比 6 大，所以 5 096 排在 5 069 前面。

greatest to smallest = tertib menurun All four numbers have 5 thousands, so compare the hundreds: the biggest hundreds digit comes first. If the hundreds are the same, compare the tens. Tap the cards in order. Example: 3 071, 3 710, 3 107 → greatest to smallest 3 710, 3 107, 3 071. Watch out: 5 096 and 5 069 look alike; both have 0 hundreds, so compare the tens: 9 is more than 6, so 5 096 comes before 5 069.

填空 = lengkapkan 先看这组数目每次是哪一位在变、变多少，再用同样的方法写出下一个数。 例子：1 326、1 426、1 526 → 每次百位加 1（加 100），下一个是 1 626。 注意：千位和十位没有变。

complete = lengkapkan Look at which digit changes each time and by how much, then use the same step to find the next number. Example: 1 326, 1 426, 1 526 → the hundreds digit goes up by 1 (add 100), so the next is 1 626. Watch out: the thousands and tens do not change.

按八递增 = bilang menaik lapan-lapan 每次加 8。如果觉得加 8 难，可以分两次加 4，或者分四次加 2。 例子：从 2 705 按 8 数：2 713、2 721、2 729。 注意：加 8 时个位常常要进位，例如 28 ＋ 8 ＝ 36，十位要多 1。

count up in eights = bilang menaik lapan-lapan Add 8 each time. If adding 8 is hard, add 4 twice, or add 2 four times. Example: counting in eights from 2 705: 2 713, 2 721, 2 729. Watch out: adding 8 often means regrouping into the tens, for example 28 + 8 = 36.
