孩子會背口訣,卻不懂乘法在算什麼? 「99乘法大挑戰」用積木把「每組幾塊、有幾組」畫出來,再配上真人語音,陪 6~8 歲的孩子先看懂、再記熟九九乘法。選單、題目和提示都會唸出來,還不太識字的孩子也能自己玩。 完整「2 的乘法」免費玩,無廣告、免註冊;教材與語音都能離線使用。 【答錯了,提示會針對孩子的答案】 孩子把 2 × 3 算成 8,App 會說「8 是 4 組 2,這題要 3 組,減掉一組 2,是多少呢?」,圖上也先畫出 4 組,再劃掉多的那一組。第一次答錯先給提示,第二次才帶著一起算,讓孩子有機會自己想通。答錯不扣星星,放心再試一次。 【不識字也能自己玩】 首頁只有一顆冒險大按鈕和「冒險地圖、練習、我的貼紙」三張圖卡。第一次打開每一區都會唸一句介紹;教完一題後的小問題也會唸出題目和選項,選項旁還有小圖,看圖就知道要按哪一個。 【先看懂,才不只是背答案】 用積木呈現乘法和重複加法的關係。9 的乘法教孩子「每組先想成 10 塊,再拿走 1 塊」,5 的乘法五個五個數,2 的乘法兩個兩個數,每一種方法都維持「每組幾塊、有幾組」,不會越教越亂。 【29 關乘法冒險,每天練一小段】 從看懂積木、練一練到小挑戰,循序練完 2×2~9×9 的 64 個算式。每天的短複習只挑該想一想的算式,平常最多 5 題;中途離開也會保留原題和輸入,下次接著練。星星和貼紙記錄孩子的努力。 【想練什麼都找得到】 「練習」有四種方式:選一個乘法練、挑一題練、聽口訣、全部混合。口訣可以整組播放,也能點一句再聽一次。 【家長陪學,有具體的下一步】 學習摘要與報告呈現近期活動、各組進度和建議練習方向。預估完成日會依孩子最近的步調,估算何時能記住全部算式;輸入學校考試日期,還能看到考前大約能記住幾題。這些日期只給家長看。學習快報可以傳給另一半或家人;每週學習單提供練習單、九九賓果、配對卡與口訣海報,完成第一組冒險後還能領取榮譽證書。 【適合一家人使用】 支援 iPhone 與 iPad,iPad 可橫向及調整視窗大小。家長可設定朗讀、音效與練習提醒;買斷後可建立多位孩子的檔案,兄弟姊妹在首頁就能換人玩。 【免費先試,適合再一次買斷】 免費:完整 2 的乘法教學與練習、家長學習總覽、報告、提醒、學習快報與 2 的乘法每週學習單。 一次買斷:解鎖 3~9 的乘法、全部混合練習、完整 64 題圖鑑、回想站、最終挑戰與多孩子檔案。無訂閱,支援 Apple 家人共享;冒險關卡仍依學習順序開啟。 學習紀錄保存在裝置上,沒有第三方追蹤或分析,不使用麥克風。購買與回復購買須通過家長驗證並連線 Apple 商店。回復購買可取回內容使用權,不會復原已刪除的學習紀錄;家人共享須符合 Apple 的共享規則。
