'Total cost of 2 items' for 2nd grade

Total cost of 2 items

Learn how to add money costs with this topic

When you buy things you need to know how much it will cost you so that you know if you have enough money to pay for them. So we use addition to calculate the TOTAL cost by adding up each item cost. Adding money is similar to adding any other numbers in math except that if the 2 numbers together add up to more than one dollar then we need to deal with both dollars and cents.

Sometimes we are just adding cents: Say we have 2 things that cost 12 cents each. To know the total cost, we simply add the 12 cents twice to get 24 cents. If the 2 items cost different amounts, we can still add up those 2 amounts to get a total cost. For example,

37¢ + 24¢ = 61¢.

When the total goes over one dollar, we need to get an answer in both dollars and cents. So if we add 75 cents and 75 cents, we have a total of 150 cents but we know that 100 cents is 1 dollar, so we have 1 dollar and a remainder of 50 cents. So the sum with answer is

75¢ + 75¢ = $1.50¢.

With our Cat and mouse math game you will be practicing the topic "Total cost of 2 items" from 2nd grade / Addition / Word problems. The math in this game consists of 14 questions that ask you to use addition to find out how much the 2 items cost in total.

Word problems: adding items and item costs

Total number of items
Total cost of 2 items
Total cost of 3 items

Sometimes in math the sums are not given to you as numbers in columns, but as words and sentences. This doesn't mean that the math you have to do is different, but it does mean you have to work out first what the sum you are being asked to do is, and then work on the sum itself. In this set of topics, the questions are to do with adding up either the total number of items or the total cost of a set number of items.

When we want to understand math problems in sentences, we need to read carefully through the sentence and create a sum that takes the number information out of the sentence and puts it in a sum. For instance, in the sentence "Jack has 6 apples and Jill has 12 apples." we can see that the things we are interested in are the apples, and the numbers we need to sum are 6 and 12. So, to get the total number of APPLES, we add up the 6 (that Jack has) and the 12 (the number of apples that Jill has). Written as a sum this will be

6 + 12 = 18

So we can say that the number of apples that Jack and Jill have is 18.

When the sentences we are looking at involve money, we have a similar situation, but our addition sum will involve adding amounts of money rather than numbers of items. Sometimes this is easy. Say we have 2 things that cost 12 cents each. To know the total cost, we simply add the 12 twice to get 24 cents. If the 2 items cost different amounts, we can still add up those 2 amounts to get a total cost. For 3 items, the idea is the same.

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.
