不再是Baby Boss的職業體驗，而是實際學習當店長！
從工作實踐裡，體認「活用數學」的重要性！
★榮獲日本設計振興會「優良設計獎」優良教材
★趣味漫畫╳經營策略╳成果驗收，揭開職場工作的祕辛
★透過7天實習經歷，鼓勵親子共同探索未來的職業和志向
★扣合SDGs永續發展目標「優質教育」、「良好工作與經濟成長」，親手打造自己的未來
「開店當老闆」可以說是每個小孩都曾經有過的夢想，這從扮家家酒中就可以窺出一二。在當老闆的遊戲中，不知不覺懂得最基本的商業之道：進貨、標價、販售、招呼客人等。但你知道，其實真的要經營好一家店，需要多少能力嗎？觀察、創造、細心……而其中，「數學力」是最不可或缺的，因為一家店能否長久經營，關鍵都在數字中，例如大家常在便利商店買飯糰，店家為了讓客人在需要的時候，無論早上或是中午時前來，都能購買到喜愛的飯糰，老闆必須計算何種飯糰賣得好、每種飯糰需要進貨多少、每天要在何時配送、為了避免飯糰賣不完，要以何種折扣促銷才不虧本……這些可不只是靠老闆的觀察力就好，而是背後都有實際的銷售管理數字，「進貨量」、「庫存量」、「銷售量」、「成本」、「利潤」、「營業額」等，這些都與數學息息相關。
本書的主角，小始和雙葉這對兄妹，一個是數學不太好的小學三年級生，一個是對世界充滿好奇，才剛學會數數的一年級生。這兩位學生數學不太靈光，卻應徵了兒童工作探究社的實習店長招聘工作，要在七天內挽救一間超倒楣便利商店，他們將會在這一週內活用所學的數學知識，習得商業經營概念與積攢社會經驗。而這七天分別能習得的能力如下：
第1天：庫存的計算
第2天：營業額的計算
第3天：利潤的計算
第4天：進貨的計畫、模擬販賣數對利潤的影響
第5天：銷售分析、統計圖表判讀、平均值的計算
第6天：經營便利商店、設計徵人廣告、對抗競爭對手的策略、思考便利商店的未來
第7天：調查商店的種類、計畫未來想經營的商店
這些訓練過程，能讓孩子鍛鍊出商業頭腦的數學力，包含「實際的計算能力」、「數學分析能力」，以及「邏輯思考能力」，繼而應用推廣到其他領域。現在就跟著小始和雙葉一起走上真正當老闆之路，你會發現，數學能在日常生活中的許多地方派上用場，絕對不是只用來應付學校的考試而已。在實踐中體會學習數學的樂趣，具備對數學事物的思考與觀察能力，就能為未來成為有能力的大人奠定更加良好、穩固的基礎。

The best vacuum cleaner ever!!
Size: E25 Black, Size: E25 Black
⭐⭐⭐⭐⭐ I honestly couldn’t be happier with the Eufy E25. I actually own two of them, and they’ve completely changed my daily routine. After spending a lot of money trying different brands, I finally found one that truly delivers everything I need in a vacuum.
The suction power is impressive, it handles pet hair and debris effortlessly, and the mopping feature actually works (not just a light wipe like others I’ve tried). The self-emptying and self-cleaning system is a game changer—it saves so much time and maintenance.
Navigation is smart and reliable, and it rarely gets stuck. It covers my floors efficiently and leaves everything noticeably cleaner. I also love how low-maintenance it is overall.
If you’re tired of wasting money on vacuums that don’t live up to expectations, this is absolutely worth it. For me, it has truly been life-changing.

Updated 1/28/2020 update 1/17/2020 It's been everything it was advertised to be and more. (Not)
Size: 11S
I called Amazon again today. Explained the situation and that no one from Amazon or Eufy had returned my calls as they promised. Also after replacing the battery at my own expense it ran 90 minutes again but got stuck everywhere, made this weird ratcheting type noise every time it changed surfaces and finally today just beeped at me twice and died. Supposedly that indicates a seized brush but they all spin freely. This time I just flat out asked them to look at my Amazon account and replace it, as I'm a very good customer. New one will be here tomorrow. I'll do a separate review on that one as it took me forever to find this one again. I'll also let you know if it's a refurbished unit or not.
Well wouldn't you know it. I leave a nice review and a few days later, Murphy's law rears it's ugly head. Device is 3 months old a couple weeks out of the exchange warranty and the battery is shot. Runs 5 or 10 minutes on a full charge. Called Amazon to see if since I am a really long standing customer if they'd help me out. Nope but we'll call Eufy support on your behalf and they will call you. We will also call you to follow up. I've been a customer service manager a lot of years and this is where employees can kill you. This Amazon person made me multiple promises. It's been a week no call from Eufy, no call from Amazon. You just turned 4 stars into 1 and if this is all the longer the batter lasts don't bother because the replacements are $25 to $30 bucks depending on the brand. I'm not spending a hundred bucks a year on batteries and this thing should be under warranty. After 3 days I ordered a new battery and Rosie is running again but I'm no longer pleased and the next time I'll buy another brand. If if this battery doesn't last the whole thing goes in the trash and I buy something else. I run this every day maybe the batteries won't take that I don't know. But if you're going to run it every day buy something else. This didn't last long enough at all.
I wanted to wait a while to be sure I had a good sampling and could post a fair and useful review. It's been 90 days now. We have two large (bigger than standard) labradoodle puppies. 85 and 50 pounds and they're 1st generation so they shed a lot. They also, being puppies, have tore the yard up so it is basically a mud pit and they wrestle, run, and fight constantly. They put a lot of dirt and hair on the floors and in the air. We run "Rosie" every day. Yes my wife named it. It does an amazing job on our hardwood floors and throw rugs. It gets all the hair and an incredible amount of dust and dirt. What I mean by that is we can run our Dyson or the Shark Pet vacuum and then run Rosie and the chamber will be full of dust and dirt when she's done. It's almost disconcerting to know our very expensive upright vacuums leave so much behind. It also has the unadvertised ability to buff our hardwood floors. They shine when she's done and the beater brush is showing no signs of damaging the finish on our floors. I would disagree with some of the reviews and even the manufacturers assertion that it doesn't work well on dark floors. Our hardwood floors are a dark reddish brown. The device works great on them and as I said when it's finished they shine. We have agreed we will never be without one and love this device. It does everything it has been advertised to do and more. Also it is set to automatic power and runs longer than the advertised time on a full charge. We get about 2 hours and 15 minutes. We've put down an additional 6 throw rugs for the rainy snow season in the path where the dogs run when they come in and the time has dropped to around 90 to 100 minutes. Still long enough to cover everything well and more than once. It does keep going until it needs a charge it doesn't just run and go back to the dock. I've noticed in the open areas like our living room it might hit that 2 or even 3 times. The floors are like glass after that.
Now for the negatives, and these are not deal breakers I'm just being fair. The dirt and dust I referred to is new to us. we recently moved from Illinois to Ohio. In Illinois the dirt is black. Here it is red or a very light brown. The vacuum gets externally dirty. It gets covered with dust/dirt and does not look good. The device is black and the dust is light colored and is readily apparent. I don't want to put it away all the time or for company so thats a problem for me and more cleaning which is not advertised so I'm mentioning it. Secondly it needs to be emptied every use or every other use. They are all like that except some of the super expensive robot vacuums so I wouldn't mention it except for my third negative. It is hard to clean from a mess standpoint. Not so much with the pet hair but with the dust. When you dump it the dust goes everywhere. Unless you have an empty trash can so you can get it way down inside when you're done the garbage can lid and sometimes the floor around the garbage can is clearly dusty from emptying the vacuum. The filters need to be removed at least every other running and they are also a big dusty mess. I also don't believe they will last as long as advertised. I have an air compressor in the garage and a hand held electric air compressor and use those to clean the filter. The foam piece I rinse in the sink. I don't think that someone without access to those tools is going to get the life out of the filters thats advertised. The device comes with a set of replacement filters and the rotating brushes. Not the beater bush though. Our unit is 3 months old. I had to replace the filters at about 40 days and tried to make them last a little longer this time but it hasn't worked out. The outside of the device is filthy. I believe this is due to the filters. The brushes have lasted longer than the suggested replacement time. They are 90 days old and still look like new. Last and has been a rare negative. The device will get stuck under things. Once I learned what the obstacles were in our home it was easy to fix. Some areas I blocked with rolled up moving blankets. I pull the chairs out from under the kitchen table to allow room for it to maneuver. If I don't it gets under there and spends way too much time cleaning and trying to get out. I'd rather it spend less time under there so it can do the whole cleaning area and have power left to do it again. I had the problem spots corrected and figured out within the first 30 days. I've read some units have a tape or something the vacuum will sense and avoid. I wish this unit had that but then again at this price point that is probably an unfair expectation.
So those are the pro's and con's we've encountered. The con's are all minor irritants and not a reason not to buy the device as all of these devices are prone to these issues except one or two of the very very expensive units. To repeat what I said earlier this device has worked out so well we have decided that we will never be without one and that when the time comes to replace her we will not feel bad about spending the money for a high dollar unit as it is worth it. Time is worth more to us than money and this thing saves us a great deal of time. It does great job, has done no damage to anything, and if it weren't for the clean up issues would be a five star review. I hope this helps someone make an informed decision and I hope you buy one. It's an amazing little machine, stands up to all the reviews, and truly is the best bang for your buck in robot vacuums.

Good for routine maintenance
The Eufy is a huge time saver, but the one annoying thing is continuously needing parts to replace it. This is where this purchase comes in - these parts fit just like the original parts, and take just seconds to install. They seem to be just as durable and functional. The brushes sweep corners well, and the filters keep the machine quiet while still pulliing in all of the dust. It's a great value to buy several at a time since they need to be replaced on a regular basis. Highly recommend!

Great set of parts for the C10
I have 3 dogs and 3 cats so my robot vacuums get run multiple times a day and need maintenance performed more frequently as a result, plus I go through a LOT of the bags. (Labradors… IYKYK.) These parts appeared identical to the originals and all fit perfectly into my vacuum. The filters and brushes were all excellent quality and the roller bar was possibly a little better than the original. The dust bags feel thinner than the original but I haven’t had any issues with them - they fit into the compartment properly and haven’t torn or broken open. It’s a good kit and I think a pretty good deal, I would definitely get it again.
