「脳内そろばん」は、そろばん式の暗算が身につくトレーニングアプリです。 画面のそろばんを指ではじいて練習するうちに表示が少しずつ消えていき、最後は頭の中のそろばんだけで計算できるようになります。 ■ 本物のように動くそろばん ・タップやスワイプで珠が動き、連動する珠も本物と同じ動きをします ・「数を作る」「数を読む」から計算まで、基礎から順にステップアップ ・まちがえたときは、正しい珠の動きをゆっくりお手本再生 ■ イメージ暗算(5つのステップ) ・常時表示 → お手本 → 半透明 → 一瞬だけ表示 → 数字のみ ・成績に合わせて次のステップが自動で解放。難しければいつでも前のステップに戻れます ■ フラッシュ暗算 ・桁数・口数・表示スピード(最速0.3秒)を細かく設定できます ・そろばん補助表示で、途中経過を珠のイメージで追いながら練習できます ■ 1日3分の「今日のトレーニング」 ・回答の記録からにがてな分野を分析し、復習メニューを自動で組み立てます ・連続練習日数の記録と毎日のミッションで、練習が習慣になります ■ 成長が見える成績画面 ・正答率・回答スピード・能力のバランスをグラフで表示 ・「5をまたぐ計算」「繰り上がり」「繰り下がり」など、つまずきの傾向も分かります ■ 保護者向けの学習レポート ・週ごとの学習時間・正答率・分野別の成績と、声かけのヒントを確認できます ・お子さまが誤って開かないよう、保護者確認つきです ■ 続けたくなる仕掛け ・経験値とレベル、コンボ、きょうのミッション ・レベルが上がると新しいそろばんのデザインが解放されます ■ 家庭で安心して使える設計 ・アカウント登録は不要。学習データは端末とご自身の iCloud にのみ保存されます(開発者には送信されません) ・機種変更や2台目の端末でも、iCloud 経由で学習データを引き継げます ・広告なし。トラッキングもありません ・上級コンテンツの購入(買い切り1回のみ)の前には、保護者確認の画面が表示されます そろばん教室に通うお子さまの家庭練習にも、はじめてそろばんに触れる方にもお使いいただけます。
