每個袋需要 2 包紙巾、1 支水和 2 包餅乾 — 桌上有這麼多物品，最多可以裝多少個袋？記住：最快用完的物品，決定可以裝多少袋！點一下物品可以標記已數過，不怕數漏！
Each bag needs 2 packs of tissues, 1 bottle of water and 2 packs of biscuits — with everything on the table, how many bags can we pack at most? Remember: the item that runs out first decides the answer! Tap an item to mark it as counted so you never lose track!
「執袋」題目是除法啟蒙中的「包含除法」（measurement division）：不是把物品平均分給幾個人，而是「每幾個一組，可以分成幾組？」— 例如 10 包紙巾，每袋 2 包，可以裝 5 袋。當物品有多種時，孩子會自然遇到「限制因素」的概念：最多可以裝多少袋，不是看最多的那種物品，而是看最快用完的那種。過程中還會遇到餘數 — 多出來的物品不夠再裝一袋，要捨去。這正是日後學習除法、餘數和應用題的重要基礎，同時訓練有系統地點數大量物品（一一對應、不遺漏、不重複）。
"Packing bags" is a gentle introduction to measurement division: instead of sharing items equally among people, we ask "in groups of this size, how many groups can we make?" — 10 tissue packs, 2 per bag, makes 5 bags. With several kinds of items, children naturally meet the idea of a limiting factor: the number of bags is set not by the item you have most of, but by the one that runs out first. Leftovers appear along the way — extras that aren't enough for another bag get set aside. This lays the groundwork for division, remainders and multi-step word problems, while training systematic counting of larger sets (one-to-one correspondence, no skipping, no double-counting).
鼓勵孩子善用「點一下標記已數」的功能 — 數一件、點一件，是有系統點數的重要策略。數完之後，先問：「每種物品夠裝幾個袋？」再問：「哪種最快用完？」答錯時，和孩子一起用手指把物品兩個兩個（或三個三個）圈成一組，親眼看到「不夠一組」的剩下來。不趕時間，慢慢數清楚最重要。
Encourage your child to use the tap-to-mark feature — counting one item and marking it at the same time is a key strategy for systematic counting. After counting, ask: "How many bags can each kind of item fill?" and then "Which kind runs out first?" When an answer is wrong, group the items with your child — circling them in twos or threes — so they can see with their own eyes that the leftovers aren't enough for one more bag. There's no rush: careful counting matters most.
在家裡玩真的執袋遊戲：拿出紙巾、水瓶和餅乾，訂一個「食譜」（每袋 2 包紙巾、1 支水、2 包餅乾），讓孩子真的動手裝，裝到不夠為止。烘焙時也可以問：「每碟放 3 件曲奇，12 件可以分幾碟？」收拾玩具時：「每個箱子放 4 輛車，這裡可以裝滿幾個箱？」動手裝過，孩子的除法概念會扎實得多。
Play the packing game for real at home: take out tissue packs, water bottles and biscuit packs, set a "recipe" (2 tissues, 1 water, 2 biscuits per bag), and let your child physically pack until the items run out. Baking works too: "3 cookies per plate — how many plates for 12 cookies?" Tidying up: "4 cars per box — how many full boxes can we make?" Children who have packed with their own hands develop a far sturdier sense of division.
