Mi hija usa la goma cuando se equivoca y luego vuelve a dibujar con la regla.

In Spain, la goma very commonly means eraser, especially a pencil eraser.

So in this sentence:

• usa la goma = she uses the eraser

A learner should know that this word can vary by region:

• In Spain: goma often = eraser
• In many parts of Latin America: goma may mean rubber, and eraser is often borrador or goma de borrar

Also, regla can mean rule or ruler, so context matters. Here, because of dibujar, it clearly means ruler.

Because the usual verb for to be mistaken / to make a mistake is equivocarse, which is a reflexive verb.

So:

• equivocarse = to make a mistake / to be wrong
• se equivoca = she makes a mistake / she is mistaken

In this sentence:

• cuando se equivoca = when she makes a mistake

Without se, equivocar usually means to confuse, to mislead, or to make someone/something wrong, and it is used differently.

Examples:

• Me equivoco mucho. = I make a lot of mistakes.
• Te equivocas. = You’re mistaken.
• Eso puede equivocar a la gente. = That can mislead people.

It can mean either, depending on context, but in a general sentence like this it often has the sense of whenever she makes a mistake.

So the whole sentence sounds like a general habit or routine:

• Mi hija usa la goma cuando se equivoca...
• My daughter uses the eraser when/whenever she makes a mistake...

Spanish often uses the present tense for habits and repeated actions.

Volver a + infinitive means to do something again.

So:

• volver a dibujar = to draw again
• vuelve a dibujar = she draws again / she goes back to drawing

In this sentence:

• luego vuelve a dibujar = then she draws again

This is a very common structure in Spanish:

• Volví a leer el mensaje. = I read the message again.
• ¿Puedes volver a explicarlo? = Can you explain it again?
• Empezó a llover y luego volvió a salir el sol. = It started raining and then the sun came out again.

Because the pattern is fixed:

• volver a + infinitive

You cannot normally say vuelve dibujar.

Compare:

• vuelve a dibujar = she draws again
• voy a dibujar = I am going to draw
• aprende a dibujar = she learns to draw

That little a is part of the grammar pattern linking the first verb to the infinitive.

Spanish often uses the definite article (el, la, los, las) where English might use the, a, or sometimes no article at all.

Here:

• usa la goma = uses the eraser
• con la regla = with the ruler

This sounds natural in Spanish because the objects are understood as the normal tools involved in the action.

English sometimes prefers:

• an eraser
• the eraser
• a ruler
• the ruler

depending on context. Spanish often uses la in these situations more broadly.

Yes. Regla has more than one meaning:

• regla = rule
• regla = ruler (the object used for measuring/drawing lines)

Here the context is drawing:

• dibujar con la regla = to draw with the ruler

So it clearly means the object, not a rule or regulation.

Both are possible, but con la regla is simpler and very natural.

• dibujar con la regla = to draw with the ruler
• dibujar usando la regla = to draw using the ruler

Spanish often uses con to show the tool or instrument used to do something:

• Escribe con un bolígrafo. = He writes with a pen.
• Corta el papel con tijeras. = She cuts the paper with scissors.
• Dibuja con la regla. = She draws with the ruler.

So con la regla is the normal everyday way to say it.

Yes. The present tense here most naturally describes a habit, a routine, or something that generally happens.

• Mi hija usa la goma... y luego vuelve a dibujar...
• My daughter uses the eraser... and then draws again...

This does not have to mean it is happening right now. It can mean:

• this is what she usually does
• this is what she does whenever the situation happens

That is very common in both Spanish and English.

Yes. Here luego means then or afterwards.

So:

• y luego vuelve a dibujar = and then she draws again

It links the actions in sequence:

1. she makes a mistake
2. she uses the eraser
3. then she draws again with the ruler

Common near-equivalents include:

• después = afterwards / later
• entonces = then

In this sentence, luego is completely natural.

Mi hija is the normal, neutral way to say my daughter.

• mi hija = my daughter

Hija mía is possible, but it usually sounds more emphatic, emotional, or literary, depending on context.

Compare:

• Mi hija usa la goma... = neutral everyday statement
• ¡Hija mía! = my daughter! / dear daughter! (more emotional or dramatic)

So mi hija is the expected form here.

Yes, you could say something like borra if you want to focus on the action of erasing rather than the object used.

Compare:

• usa la goma = she uses the eraser
• borra = she erases

Possible rewording:

• Mi hija borra cuando se equivoca y luego vuelve a dibujar con la regla.

That is grammatical, but it changes the focus slightly:

• usa la goma highlights the tool
• borra highlights the action

The original sentence is perfectly natural if the goal is to practice vocabulary like goma and regla.

The sentence breaks down like this:

• Mi hija = subject
• usa la goma = first verb phrase
• cuando se equivoca = time clause: when/whenever she makes a mistake
• y luego = and then
• vuelve a dibujar = second verb phrase: draws again
• con la regla = prepositional phrase: with the ruler

So the overall structure is:

• [Subject] + [main action] + [time clause] + y luego + [next action] + [instrument]

That makes the sentence very typical and easy to model for similar examples.
