Number Skills Inventory

This is a simplified list of mathematical skills that pupils should have. It has been designed so that each idea has five levels making it visually easy to see where a pupil is now and what they need to do to improve.

Decimals	Add and subtract basic decimal numbers ExampleActivity	Use decimals in real life situations (eg money) ExampleActivity	Multiply and divide decimal numbers by whole numbers ExampleActivity	Multiply decimal numbers ExampleActivity	Divide decimal numbers ExampleActivity
Fractions	Understand notation, simplifying and simple equivalence ExampleActivity	Add and subtract fractions with a common denominator ExampleActivity	Multiply and divide fractions ExampleActivity	Add and subtract fractions which don't have a common denominator ExampleActivity	The four rules of fractions and mixed numbers ExampleActivity
Factors	Find factors of numbers informally ExampleActivity	Know the properties of prime numbers ExampleActivity	Find all the factors of a number ExampleActivity	Find the HCF and LCM of two numbers ExampleActivity	Use the properties of numbers to solve problems ExampleActivity
Percentages	Understand the concept and estimate percentages ExampleActivity	Calculate with simple percentages such as 50% and 75% ExampleActivity	Calculate with everyday percentages in real life problems ExampleActivity	Express percentages as fractions and decimals ExampleActivity	Solve problems involving percentage change ExampleActivity
Ratio	Identifying ratios from pictures ExampleActivity	Simplifying ratios ExampleActivity	Simplifying ratios with fractional parts ExampleActivity	Dividing a quantity in a given ratio ExampleActivity	Using ratios in real life ExampleActivity
Estimating	Estimate instead of counting ExampleActivity	Estimate lengths ExampleActivity	Estimate the size of angles ExampleActivity	Approximate to give estimated solutions to problems ExampleActivity	Estimate the results of calculations ExampleActivity

Please note that the main objective of creating this inventory grid was to produce something that provided visual impact. Each of the ideas or concepts has been broken down into five levels. This has been done for consistency so the differences in the difficulty between levels is not the same in all cases. Please let us know if you have any suggestions for improvement.

The activity buttons will take you to the nearest match activity on the Transum website. The activity is not always an exact match for the statement but is the closest available.

This page should print nicely for you records or can be used online. The page should remember your ticks from one visit to the next. It does this by using Local Storage so the information is saved only on the computer you are working on right now.

Transum subscribers can use this page as part of the Class Admin system keeping a record of progress for each and every student in the class.

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 1 February 'Starter of the Day' page by M Chant, Chase Lane School Harwich: "My year five children look forward to their daily challenge and enjoy the problems as much as I do. A great resource - thanks a million."		Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month. The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing. Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.
Featured Activity Snooker Investigation Given the width and height of a snooker table can you predict which pocket the ball will end up in and how many times will it bounce off one of the sides?	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.
