Instructions

Try 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.

Why am I learning this?

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 6 May 'Starter of the Day' page by Natalie, London:

"I am thankful for providing such wonderful starters. They are of immence help and the students enjoy them very much. These starters have saved my time and have made my lessons enjoyable."

Comment recorded on the 14 September 'Starter of the Day' page by Trish Bailey, Kingstone School:

"This is a great memory aid which could be used for formulae or key facts etc - in any subject area. The PICTURE is such an aid to remembering where each number or group of numbers is - my pupils love it!
Thanks"

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 page is an alphabetical list of free activities designed for students in Secondary/High school.

"The questions in the six levels of this of exercises range from the laughingly easy to the head-scratchingly hard. The last question of level 6 was adapted from one that appeared on a Senior Mathematical Challenge (SMC) paper.

The SMC is a 90-minute, multiple-choice competition from the UK Mathematics Trust aimed at students (Year 13 and below) across the UK. It encourages mathematical reasoning, precision of thought, and fluency in using basic mathematical techniques to solve interesting problems. The problems on the Senior Mathematical Challenge are designed to make students think. Most are accessible, yet still challenge those with more experience."

"The directions say to measure the side lengths to the nearest centimeter, then those side lengths to calculate area and perimeter. If you do that for the middle parallelogram, you get a base of 5 cm and height of 2 cm. The area should be listed as 10 square cm. It is only if you measure the side lengths to the nearest HALF cm that you come closer to the "correct" answer of 12 square cm, which should actually be 13 square cm when 12.5 (2.5 x 5) is rounded to the nearest whole number.

[Transum: Thanks for pointing out this issue Mindy. It is interesting that because of the rounding instruction a different value for the area is obtained depending on whether you use the horizontal line as the 'base' or choose to consider the sloped line as the 'base'. The software now marks either version as correct. Thanks again for taking the time to point this out. A great thing to discuss with students.]"
