I am allowing my nephew to consult the tables or the calculator when solving step by step a long multiplication. The idea was that in this way she will finally memorise the tables via practising. But when consulting the tables she becomes distracted, and in the calculator she needs to look for the times and then the equals sign and then the continuity of the phrase "6 por 8, 48" is lost, I am afraid she gets the value "48" from the screen but separated from the "index key", "6 por 8".
