「かけざんで あそぼ」は、小学2〜3年生のお子さまが、九九と あまりのないわり算 を身につける知育アプリです。九九を丸暗記させるのではなく、「同じ数のまとまりが いくつ分」という かけ算の意味から入ります。 【3つのあそび】 ● ぜんぶで なんこ(かけざん) 3こずつ入ったおさらが4まい。ぜんぶでなん個かを数字カードから選びます。おさらを1枚ずつタップすると「3こ・6こ・9こ…」と読み上げるので、飛ばし数えがそのまま九九の土台になります。 ● おなじ かずに わけよう(わりざん) 12こを4さらに同じ数ずつ分けると、1さらなん個になるかを選びます。答えるまでおさらの中身は伏せてあるので、絵を数えるだけでは答えられません。答えたあとに分けた結果が見えて、なぜその数になるのかを確かめられます。 ● なんばい かな 「3 × □ = 12」の □ を答えます。かけ算の式のままわり算を考えることになり、2つの計算が同じものだと気づけます。 【3つのレベル】 ・レベル1:2のだん・5のだん(おぼえやすい だん) ・レベル2:3のだん・4のだん ・レベル3:6・7・8・9のだん(むずかしい だん) レベル3は下のレベルの段を含まず、覚えにくい段だけを練習します。1セット6問、4問正解でクリアするとシールが1枚もらえ、次のレベルが解放されます。集めたシールは「シールちょう」でいつでも見返せます。 【まちがえかたにも意味があります】 選択肢の中には、必ず「同じ段のとなりの答え」を混ぜています。たとえば 9×8 の選択肢には 63(9×7)が入ります。数の大きさを見ただけでは選べないので、九九を思い出す練習になります。 【あんしんのポイント】 ・広告は一切表示されません ・当社のサーバーとの通信は行わず、学習の記録は端末の中だけに保存されます(通信は Apple の購入手続きのみです) ・レベル1・2は無料で遊べます。レベル3は買い切り(480円)の「ぜんぶあそべる」で、3つのあそびすべてが遊べるようになります。購入画面は保護者向けの確認(かけ算)の先にあります ・アカウント登録・ログインは不要です ・減点や時間制限はなく、間違えても正解を見せてすぐ次に進みます ・iPhone・iPadの両方に対応 保護者の方へ:くだものは答えを確かめるための道具です。絵を数えるだけで答えてしまうようになったら、設定で表示を「いつも見せる」「ヒントを押したときだけ」「見せない」から選べます(ホーム右上の歯車から、2桁×2桁のかけ算の答えを入力して開きます)。数えて確かめるところから、九九で答えられるところへ、無理なく進めるようにしています。正誤の合図に色を使わないため、色の見え方に関わらず遊べます。
