ROCK FALL game to practice
'Add centimeters to meters' for 3rd grade

Add lengths given in centimetres and metres

To add lengths measured in metres and centimetres, you need to first convert the metres to centimetres. This is because metres and centimetres are different units of measurement for length, and you cannot directly add them without first converting them to the same unit. Here's how to do it:

Convert metres to centimetres: As there are 100 centimetres in a metre, you need to multiply the number of metres by 100 to convert it to centimetres.

For example, let's say you are asked to add 2 metres and 35 centimetres. To convert the 2 metres to centimetres, you would multiply by 100:

2 metres x 100 = 200 centimetres

Now that you have the metre length in centimetres, you can add it to the other length which is already in centimetres.

In our example, we converted 2 metres to 200 centimetres, and we also have 35 centimetres. To add them together:

200 centimetres + 35 centimetres = 235 centimetres

So, the combined length of 2 metres and 35 centimetres is 235 centimetres.


Another example, add 0.9 metres and 74 centimetres.

Converting the metres to centimetres we have 0.9 m x 100 = 90 cm.

Adding the centimetres we have 90 cm + 74 cm = 164 cm.

So, the combined length of 0.9 metres and 74 centimetres is 164 centimetres.


This topic asks you to add lengths in metres and centimetres together by first converting the metres to centimetres. Your answers should be in centimetres.

With our Rock fall math game you will be practicing the topic "Add centimeters to meters" from 3rd grade / Measurements / Calculate. The math in this game consists of 18 questions that ask you to add lengths by converting meters into centimeters and then adding the measurements 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.
