你一半，我一半: : 3 8 1 2
作者/ 繪者: 曹俊彥 | 適讀年齡: 3-8 |
發現數學的趣味，體會分享的快樂！
兩個人分兩個蘋果，一人一個剛剛好。
兩個人分一條香腸，一人一半剛剛好。
兩個人分一塊圓蛋糕和一塊方蛋糕，怎麼分才剛剛好？
兩個人分一隻狗，怎麼分才剛剛好？
本書運用日常生活中常見的事物，讓小朋友對「分數」有初步的概念，同時也讓孩子體會到「公平分配」之外，有時也能享受「分享」的快樂。
兩個蘋果，兩人分，
一人一個，剛剛好。
一條香腸，兩人分，怎麼分，切開來。
你一半，我一半，兩塊一樣大，剛剛好。
好多糖果，兩人分，你一個，我一個，你再一個，我再一個，
再一個，再一個，分完了，剛剛好，你一半，我一半，我們一樣多。
本書特色
1 快樂學數學
以生活中常遇到的情況為例子，引導孩子對數學「有感覺」。
2 教導「公平分配」的概念
書中運用像是紅蘿蔔要根和葉都分到的例子，教導孩子「一半」在數學中的精準意義是指分配「平均」。

Great for keeping bank statements clean but random security delays are frustrating
Reload type: One Time Reload
I use the balance reload tool to manage my monthly budget and easily hit credit card sign-up bonuses. It keeps my bank statements totally clean by grouping dozens of tiny e-book and movie rental charges into one single transaction. Most of the time the whole process works flawlessly and the money shows up in my account within five minutes. It is honestly the easiest way to put a hard limit on my family's everyday online shopping.
You just need to watch out for a few annoying system quirks when you load larger amounts of money. Even though it usually works instantly the automated security filter sometimes flags big reloads and freezes the transaction for hours. This random delay is incredibly frustrating if you are trying to add cash fast to catch a lightning deal before it expires. You also have to remember that this balance is strictly non-refundable and cannot be used to buy other gift cards.
Overall this is still a great method for organizing online spending and maximizing your cash-back credit card rewards. It totally fixed how I track household purchases but you definitely have to tolerate the occasional processing delays. My best advice is to load your account a day or two before you actually need to buy a big-ticket item. It works perfectly as a budgeting tool as long as you know the rules and plan for the random security hold.

Very good wireless mouse

Everything is great with this mouse. It is comfortable, responsive, and easy to use. The wireless connection works perfectly, and the battery lasts a long time. Very good value for the price, I highly recommend it.
