How many minutes should an elementary school child’s online English lesson be?

When you look into online English lessons, you will often see 25-minute and 40-minute options. There are also 50-minute lessons. Longer lessons seem as though they will lead to more learning, so the longer option draws your attention. The pricing is structured that way too.

But the child determines the lesson length. The service does not. If a second grader starts leaning back after about 20 minutes, even with a 40-minute lesson, the actual learning happens in the first 20 minutes. The rest is time spent sitting in front of a screen.

That is why this article does not give a single correct number of minutes. It explains how to measure the right number for your child.

01Measure it at home first

You can check at home before applying for a trial. Have your child do an activity they like and see how many minutes pass before their posture starts to slip. They can read a book or make something.

For a demanding subject like English, the time will be shorter. Set it below the amount of time they can stay engaged with something they like. You do not need an exact number, just a rough sense.

You can check once more during the trial lesson. At some point, your child will go from leaning toward the screen to resting their back against the chair. Look at the clock. That point is your child’s lesson length for that day.

02Speaking density matters more than length

Even within the same 25 minutes, the amount a child speaks can vary greatly. In some lessons, the teacher spends a long time explaining. In others, the teacher keeps asking questions.

Count and you will see it right away: the number of times your child speaks. Leave out nods and answers that end with yes or no. If this number is low, increasing the lesson length will not make much difference. The problem is the lesson structure.

Conversely, some lessons are short but have a high speaking density. Even a short lesson leaves more behind than a long one if the child’s turn to speak keeps coming around. Check this number before considering the length.

03By grade level

Children differ even within the same grade. Use grade level only as a reference; measuring your own child will be more accurate.

04Spacing matters more than frequency

You will also need to decide how many lessons to schedule each week. What is often overlooked here is the spacing.

Some families schedule two weekly lessons on Monday and Tuesday. Parents’ schedules sometimes make this necessary. But that leaves a five-day gap from Wednesday through Sunday. During that time, the expressions from the previous week fade.

The same two lessons work differently when they are spaced out, such as on Monday and Thursday. The child keeps coming into contact with English every three days. If increasing the frequency is difficult, adjust the spacing first. This adjustment costs nothing.

05The time slot matters as much as the length

Children are hungry right after school. They are sleepy right after dinner. After returning from an academy, they are already tired. Even with the same 25 minutes, half the lesson goes to waste when scheduled at these times.

Find a period when your child’s condition is consistent. Around 30 minutes after a snack is generally a reasonable time. Every household is different, however, so it is more accurate to observe for a couple of weeks before deciding.

The family’s schedule must also be clear at that time every week. No matter how good the time slot is, absences will accumulate if it overlaps with an academy schedule every other week.

06When to increase the lesson length

You can increase it once your child starts handling a short lesson comfortably. There are signs: asking to continue after the lesson ends, repeating learned expressions alone afterward, or preparing questions for the teacher in advance.

There are also signs that you should not increase it: refusing before the lesson starts, frequently going to the bathroom during the lesson, or giving increasingly shorter answers. Increasing the length at this point will make the child dislike English itself.

When increasing it, do not double it all at once. Increasing 25-minute lessons to 3 times a week is less burdensome for the child than going from 25 minutes to 40 minutes.

07Time needed before and after the lesson

A 25-minute lesson does not take only 25 minutes. Extra time is needed before and after it.

It takes about 5 minutes to turn on the device, connect, and get settled before starting. The child will not get up immediately afterward either. Any homework adds more time. In practice, you need to set aside close to 40 minutes.

If you do not account for this when planning the schedule, you will be rushed every time. There will be days when you have to leave as soon as the lesson ends, and on those days the child cannot wrap up properly. Allow 10 minutes of leeway before and after. This also gives you time to ask what they did that day after the lesson.
