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 you have to take care of converting from coins to notes.

For instance, if I went and bought 2 things at 90 cents each, what would the total cost of the items be?

90¢ + 90¢ = 180¢ = $1.80

So when the total goes over one dollar, we need to get an answer in both dollars and cents. So if we add 90 cents and 90 cents we have a total of 180 cents but we know that 100 cents is 1 dollar, so we have 1 dollar and a remainder of 80 cents.

With our Cat and mouse math game you will be practicing the topic "Total cost: 2 items" from 3rd grade / Addition / Word problems. The math in this game consists of 14 questions that ask you to use addition to find out the total cost of the 2 items.

Word problems: adding items and item costs

Topic titles:

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

Sometimes in math the problems are not given as numbers 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 of 2 or 3 items.

When we want to understand math addition word problems, we need to read carefully through the text and create the sum that takes the number information out of the text and puts it in a sum. When we read the text "Logan has 30 Rich tea biscuits and 17 Digestives" we can see that the sum involves finding how many biscuits Logan has in total which we find by adding up the number of Rich tea biscuits and digestive biscuits. So the total number of biscuits is 30 + 17 which is 47.

When the sentences we are looking at involve money our addition sum will involve adding amounts of money rather than numbers of items. Given the text "Grace buys 3 pencils for 54¢, 64¢ and 75¢." we realise that we need to add the 3 amounts to come to the total that Grace has spent on pencils. Because that total is greater than 100¢, the answer will be in both dollars and cents. Can you work out what that amount will be? Try the topic "Total cost of 3 items" to check your answer.

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...

  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.
