Catch a Bouncing Ball Operations by mathies is a game that provides opportunities to practise the fundamental skills of addition, subtraction, multiplication or division. For single operation games the unknown value is the result (e.g., 3 + 5 = ?). For mixed operation games the position of the unknown value changes (e.g., 3 + ? = 8). The player determines the unknown value and drags the glove to the correct answer on the number line.
