ROCK FALL game to practice
'Add liters and milliliters' for 3rd grade

Add millilitres to litres

To add litres and millilitres together, you first need to convert the litres to millilitres. This is because litres and millilitres are related but different units of measurement for volume, and you cannot directly add them without first converting them to the same unit. Here's how to do it:

Convert litres to millilitres: As there are 1,000 millilitres in a litre, you need to multiply the number of litres by 1,000 to convert it to millilitres.

For example, let's say you have 3 litres and 250 millilitres. To convert the 3 litres to millilitres, you would multiply by 1,000:

3 litres x 1,000 = 3,000 millilitres

Add the converted volume to the millilitres: Now that you have the volume in millilitres, you can add it to the other volume, which is already in millilitres.

3,000 ml + 250 ml = 3,250 ml

So, the combined volume of 3 litres and 250 millilitres is 3,250 millilitres.


Another example, add 1.3 litres and 740 millilitres.

Converting the litres to millilitres we have 1.3 L x 1,000 = 1,300 ml.

Adding the millilitres we have 1,300 ml + 740 ml = 2,040 ml.

So, the combined volume of 1.3 litres and 740 millilitres is 2,040 millilitres.


This topic asks you to add volumes in litres and millilitres together by first converting the litres to millilitres. Your answers should be in millilitres.

With our Rock fall math game you will be practicing the topic "Add liters and milliliters" from 3rd grade / Measurements / Calculate. The math in this game consists of 16 questions that ask you to add liters and milliliters by converting the liters to milliliters and then adding the volumes together.

Large thumbnail for math game Rock fall

ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.

There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
