AlgebragonsFind the missing expressions in these partly completed algebraic arithmagon puzzles. |
Complete the algebragons. The expressions in the rectangles are the products of the mixed (including fractions) expressions in the adjacent circles. Use the ^ key to type in an exponent or index. Type in your answers in descending powers of \(x\). Use the forward slash / to type a fraction and use brackets if the numerator has more than one term.
InstructionsTry your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help. When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file. |

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" Comment recorded on the 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary: "I use Starter of the Day as a registration and warm-up activity for my Year 6 class. The range of questioning provided is excellent as are some of the images. |

Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school. Maths MapAre you looking for something specific? An exercise to supplement the topic you are studying at school at the moment perhaps. Navigate using our Maths Map to find exercises, puzzles and Maths lesson starters grouped by topic. | ||

Arithmagons - The same sort of puzzle but with numbers not algebra.
Level 1 - The expressions in the rectangles are the sums of the linear expressions in the adjacent circles.
Level 2 - The expressions in the rectangles are the sums of the linear and quadratic expressions in the adjacent circles.
Level 3 - The expressions in the rectangles are the products of the monomial expressions in the adjacent circles.
Level 4 - The expressions in the rectangles are the products of the binomial expressions in the adjacent circles.
Level 5 - The expressions in the rectangles are the products of the mixed (including fractions) expressions in the adjacent circles.
Fractionagons - Different topic, same structure.
More Algebra including lesson Starters, visual aids, investigations and self-marking exercises.
Use the ^ key to type in a power or index then the right arrow or tab key to end the power.
For example: Type 3x^2 to get 3x2.
Use the forward slash / to type a fraction then the right arrow or tab key to end the fraction.
For example: Type 1/2 to get ½.
Fractions should be given in their lowest terms.
Use brackets if the numerator has more than one term.
Don't wait until you have finished the exercise before you click on the 'Check' button. Click it often as you work through the questions to see if you are answering them correctly. You can double-click the 'Check' button to make it float at the bottom of your screen.
Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.
Here are some suggestions for how you may solve the puzzles in which only the three expressions in the rectangles are given (the last question in levels three and above):
Replace 'sum' with 'product' if the operation is multiplication.
This was found by Ann Roberts, a Transum subscriber, who wrote with this method of solving an arithmagon with 18, 15 and 11 in the rectangles. It also works for algebraic expressions.

"Lovely activity, particularly like the fact that the answers do not accept 1x and that you have to write the powers of x in decreasing order."
