まなぶ Learn 数学のべんきょう Junior High Math Study
中学3年分の数学を、計算から証明まで練習できる学習アプリ。答えだけでなく「次にどの操作をするか」を選ぶ手順モード、証明の行を並べて根拠を選ぶ証明モードを収録。角度や三平方は図を読んで答え、文章題は式の立て方から。わからないときは答えを伏せた「考え方」が見られます。学習指導要領(平成29年告示)の数と式・図形・関数・データの活用に準拠した全17単元。 A junior-high math app covering all three years, from calculation to proof. A step mode asks which operation comes next instead of just the answer; a proof mode has you order the lines and pick the reason. Angles and the Pythagorean theorem are answered from figures, and word problems start with setting up the equation. When stuck, a hint shows the approach without giving the answer. 17 units aligned with the MEXT curriculum.
