Game: FOUR IN A ROW
Aim: To get four symbols in a row
Method:
Choose a square and click on it. Click on the correct answer to the question in the box that appears. If you are right the square is replaced by a tick. Continue until you have won 4 in a row...
When you buy things you need to know how much it will cost you so that you know if you have enough money. We use addition to calculate the TOTAL cost by adding up each individual item cost. Adding money is similar to adding any other numbers in math except that if the 3 numbers together add up to more than one dollar then we need to deal with both dollars and cents.
Sometimes we are just adding the cents: Say we have 3 things that cost 22 cents each. To know the total cost, we simply add the 22 cents three times to get 66 cents. If the items cost different amounts, we can still add up those 3 amounts to get a total cost:
15¢ + 23¢ + 34¢ = 72¢.
When the total goes over one dollar, we need to get an answer in both dollars and cents. So if we add 75 cents, 75 cents and 75 cents we have a total of 225 cents but we know that 200 cents is 2 dollars, so we have 2 dollars and a remainder of 25 cents. So the sum with answer is
75¢ + 75¢ + 75¢ = $2.25¢.
With our Four in a row math game you will be practicing the topic "Total cost: 3 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 how much the 3 items cost in total.
Topic titles:
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.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
