The CAT AND MOUSE 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 Cat and mouse 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.

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...

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.
