Go Figure

Dude

Place the numbers on the Go Figure grid so that the four calculations are correct.

The two digits on the leftmost yellow spaces should add up to the number on the red space below. In a similar way the other three calculations shoud be correct.

A good strategy is to start by indicating which numbers could not possibly go on certain spaces. To help you record this information small clickable tags will appear when you click the button below.

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 23 September 'Starter of the Day' page by Judy, Chatsmore CHS:

"This triangle starter is excellent. I have used it with all of my ks3 and ks4 classes and they are all totally focused when counting the triangles."

Comment recorded on the 9 April 'Starter of the Day' page by Jan, South Canterbury:

"Thank you for sharing such a great resource. I was about to try and get together a bank of starters but time is always required elsewhere, so thank you."

Without Lifting

Without Lifting

Can you draw these diagrams without lifting your pencil from the paper? This is an interactive version of the traditional puzzle. Some diagrams are possible while others are not. What is the rule?

Numeracy

"Numeracy is a proficiency which is developed mainly in Mathematics but also in other subjects. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures. It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables."

Go Maths

Learning 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 main page links to more activities designed for students in upper Secondary/High school.

"One method of finding a solution to a puzzle in which the digits one to nine have to be arranged in a particular formation is by trying every different permutation. This strategy however is very time consuming. Even if it only took one second to arrange the numbers and check whether a solution has been found, you would need to allow over one hundred hours to complete the task!

Developing a strategy with some insight or consideration of the number patterns might be a better course of action.

Use the tags to record which numbers cannot possibly go into certain spaces. For example the nine could not possibly go into the yellow spaces of the addition column as any other number added to the nine would give a two digit answer but the answer should be one digit number.

The one cannot possibly go into the multiplication calculation as any number multiplied by one would equal that same number and you only have one copy of each number to put into the spaces.

A prime number cannot go into the space at the top of the division calculation. There are many more such restrictions that you can record by clicking on the tags which will help you solve this wonderful puzzle. "
