The CAT AND MOUSE 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 Cat and mouse 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.

Move the cat to catch the white mice, hit the blue balloons, but avoid the red ones

Large thumbnail for math game Cat and mouse

Cat versus mouse game with added balloons for math and fun. You are the ginger cat, and your life is being made a misery by some white mice which have come into the house and are proving hard to catch. Not to mention there is a mouse house party going on and lots of balloons getting in the way of your hunting.

So you have to catch the white mice, forget about the gray mice, hit the blue balloons but avoid the red balloons, and answer math questions (you are a CLEVER cat...). If it sounds complicated and a bit frantic, that's because it is. Do your best but don't worry if you can't catch all the mice - neither can we. It's a cat's life...

How to play CAT AND MOUSE to practice
'Add centimeters to meters' for 3rd grade

Free Math Games screenshot of the CAT AND MOUSE game for elementary

CAT AND MOUSE is a quirky take on the perennial enmity of ponderous predator and plucky prey. Here are the basics:

  1. Press "PLAY" on the CAT AND MOUSE settings page to open the game.
  2. You are a ginger cat overwhelmed by a serious mouse problem.
  3. Luckily your job is only to catch the white mice, not all the mice.
  4. Trouble is, they are not easy to catch and will try to avoid you.
  5. Use the arrow keys or tap the screen in the direction you want the cat to go.
  6. You will need fast reaction times to catch those white mice, and the balloons keep getting in the way.
  7. Mouse scores are 25 points for each white mouse caught, minus 5 points for each white mouse that escapes.
  8. When you do catch a white mouse, a math question will appear.
  9. Answer the math question correctly for those extra points...
  10. You get 50 points for each correct answer, but you lose 25 points for each wrong answer.
  11. Hitting blue balloons gives you extra points, but 3 hits on a balloon will burst it for that level.
  12. Hitting red balloons takes away points.
  13. Balloon scores are +5 or +10 points for blue balloons, -5 or -10 points for red balloons.
  14. This is a timed game and your final score is calculated by taking away your time in seconds from the points you have earned.
  15. If you get one of the 10 best scores you can add your name to the leaderboard for your chosen topic.
