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...
5th grade / Multiply + Divide / Best Price / Best price - divide by 9
With our Four in a row math game you will be practicing the topic "Best price - divide by 9" from 5th grade / Multiply + Divide / Best Price. The math in this game consists of 14 questions that ask you to use division by 9 to work out the saving made by purchasing a packet of 9 rather than individual items.
In these math topics, we explore division by working out what the price per item is if you buy a whole pack or other group container like a box or a book (of stamps). Often retailers will price a group of items in a box or packet at less per item in order to sell a greater quantity of items.
For instance, buying individual marbles might cost 10 ¢ each, but buying a packet of 10 marbles might cost say 80 ¢. In this case, you can probably see immediately that the pack price is "better" than the individual price, but how can we work out what the acutal saving is? There are 2 simple ways to work out the saving: either multiplying the individual item price by the number of items sold in the packet, or dividing the packet price by the number of items in the packet. If we do the latter we find that the price of each marble in the packet is
80 ¢ ÷ 10 = 8 ¢
Which compares to 10 ¢ if we buy the marbles individually. So in this case the saving ** per item ** (which is what these topics are about) is:
10 ¢ - 8 ¢ = 2 ¢
Next time you are in a shop where you can choose to buy a packet or individual items, see if you can figure out what the saving is... it could save you a packet!
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
