教師支援アプリ! 中学数学のグラフを、自由に傾きなどを変化させて直感的に分かりやすく表示できます。 【特徴】 ・使用が簡単 iPhoneかiPadに表示させて、教室のテレビやスクリーンに映すだけ。面倒な電子黒板の準備や移動教室は不要です。 ・時間短縮 グラフ黒板に大きな定規を使ってグラフを書く時間がなくなります。格子点も追加できるのでグラフを通る座標の説明もこのアプリだけで問題ありません。 ・グラフの傾きなどを動かせるので分かりやすい 「傾きが大きくなるとグラフはどうなる?」「傾きが0の時は?」など直感的に分かりやすく示すことができます。 ・格子点表示 好きな座標に格子点を打つことが可能。A ,B,C…のラベルも自動で付くので説明もしやすいです。 ・見やすいレイアウト シンプルなレイアウトで見やすい。 ・追加機能続々 変域、傾きの求め方、・・・ 今後のアップデートで新機能追加予定です。 機能のリクエストもお待ちしています!デベロッパのWebサイトからリクエストしてください。
