Multiplying and dividing by powers of 10 (10, 100, 1000, etc) is an important skill that will help you to work out decimals, percentages and converting measurements. You can use a number slider to work out the problems here.

Here are the rules for converting fractions to decimals and percentages. Try the BBC Skillwise Fractions, Decimals and Percentages game. A video on how to change fractions and decimals to percentages here. Some more interactive maths games about fractions, decimals and percentages.

Year 6/7 Maths

Year 6 and 7 mentors and administrators

Congratulations to all those students who were nominated and selected as mentors and administrators for this year. Mrs Murnane, Mrs O’Connor and I are very proud that you are all prepared to take on the extra responsibilities that your new roles will entail. Congratulations also to all those students who participated in activities on the Roses Gap Adventure camp last week, especially those that worked as a team and were encouraging their group members to achieve their best.

This week in maths we will continue to develop our understadning of decimal numbers. Those that completed the activity ‘Comparing Decimals’ with ease last week will go onto performing operations with decimals – visit BBC – KS3 Bitesize: Maths – Decimal Activities and complete the activites and the quick test. (Just treat the English pound symbols as dollars!). Save the score page to show me, so I can check your work. For more on adding and subtracting decimals you can use the National Library of Virtual Manipulatives Base Block Decimals. Use the Decifractator to convert fractions to decimals. Use the decimal number line to visualise the numbers in between.

More decimal activities can be found at FUSE. Type in the following codes for each activity:

Scale Matters: decimal numbers – YDWE83

Wishball: hundredths – 225PL8

Gamequarium: Decimal Games – 24PTEG

The students that had some difficulty in comparing the size of decimal numbers will work with me to improve their understanding using some computer games and a dice game called “Crocodiles and Sharks”.

Before the end of term I hope to start a short unit on percentages – please save all those advertising catalouges with sale prices advertised, so we can use them in class.
