Download a one side worksheet with some workshop questions on number. Some symbolic questions (equivalent fractions, multiplication) and some word problems (VAT increase).

The main phase of the lesson was about probability. Packs of playing cards, coin tossing, and a discussion about smoking cessation, the National Health, and individual behaviour versus averages. Good stuff, and I’ll post an evaluation here in a bit.

More workshop questions http://bodmas.org/blog/maths/more-workshop-questions/ http://bodmas.org/blog/maths/more-workshop-questions/#comments Sun, 03 Jan 2010 22:32:16 +0000 Keith Burnett http://bodmas.org/blog/?p=1011 Download a pdf file with 20 questions about number topics.

This will get people back into the groove after the holiday. I allow about 30 minutes for this kind of worksheet. I have back up activities for the more confident students.

Focus on equivalent fractions, rounding, and some questions embedding the four functions including with whole numbers and one or two decimal number questions in familiar contexts. No answers as yet but I might write a set out.

Quick fire number questions http://bodmas.org/blog/maths/quick-fire-number-questions/ http://bodmas.org/blog/maths/quick-fire-number-questions/#comments Mon, 07 Dec 2009 21:57:36 +0000 Keith Burnett http://bodmas.org/blog/?p=968 John Cage

Download a one side pdf worksheet with 30 quick fire non calculator number questions and numerical answers.

Questions include the four functions with whole numbers and decimal numbers, a few fractions questions including adding related ‘family’ fractions, percentages and fraction conversion, some ratio and rounding and a few problem questions. Designed as a sort of ‘speed trial’.

Revision PowerPoint http://bodmas.org/blog/maths/revision-powerpoint/ http://bodmas.org/blog/maths/revision-powerpoint/#comments Sun, 29 Nov 2009 20:05:56 +0000 Keith Burnett http://bodmas.org/blog/?p=956 New range of fractions un Unicode

The symbol palette in Microsoft PowerPoint has always included the quarter fractions. Now you get the thirds and the eighths. Handy for quick revision PowerPoint presentations.

You can download a PowerPoint file with 20 slides with quick revision questions for level 1 Maths students. Covers money calculation questions, area and perimeter questions, unit conversion questions, questions about finding fractions and percentages of quantities, and some directed number work.

You can also download a PDF file with the same 20 slides. The PDF version seems to be a lot smaller (200kb).

Estimating http://bodmas.org/blog/maths/estimating/ http://bodmas.org/blog/maths/estimating/#comments Thu, 24 Sep 2009 08:58:47 +0000 Keith Burnett http://bodmas.org/blog/?p=873 Copy and complete the table question from level 2 homework sheet

Download a one side handout with some estimation and BODMAS examples used for homework.

This one side homework was produced by copying and pasting from other worksheets I have written over the last few years. Definitely a 20 minute task. We use estimation questions as a way for students to show understanding of the sequence of operations as well.

Why (teachers) should blog http://bodmas.org/blog/ilt-ideas/why-teachers-should-blog/ http://bodmas.org/blog/ilt-ideas/why-teachers-should-blog/#comments Tue, 28 Jul 2009 15:22:30 +0000 Keith Burnett http://bodmas.org/blog/?p=826

A spin on Godin’s (the bald one) first few sentences: Running a class blog for students gets the teacher searching for really good Web links that fit that particular lesson’s content and that help students understand it. As Dave C (the chemist blogger) has worked out, you can use those links next year and in other contexts. It takes 20 minutes a week.

Foreign currency http://bodmas.org/blog/maths/foreign-currency/ http://bodmas.org/blog/maths/foreign-currency/#comments Sun, 19 Jul 2009 10:41:13 +0000 Keith Burnett http://bodmas.org/blog/?p=821 leaving multiply returning divide

Download one side on foreign currency conversion. It explains converting from Sterling to foreign currency and back again, and has a few questions of each kind. The worksheet assumes that students will use calculators.

I was searching for Web pages with simple explanations of the topics in the Number unit of an access maths module so that I could make a ‘hyperlinked calendar’ of topics for each week. I couldn’t find anything sensible for foreign currency so I wrote this. Spatchcocking together examples and YouTubes and demonstrations and quizzes from lots of different sources on the Web sounds good in principle but there are drawbacks in practice.

Part of 20 Minutes, although it took about 40 minutes really.

48 Numeracy Questions http://bodmas.org/blog/maths/48-numeracy-questions/ http://bodmas.org/blog/maths/48-numeracy-questions/#comments Tue, 23 Jun 2009 14:11:44 +0000 Keith Burnett http://bodmas.org/blog/?p=803 48 level 1 ish maths questions

Download a PDF with 48 Numeracy Level 1 questions broken down into 4 ‘days’ worth of homework. Each homework lasts about 20 minutes.

  • Whole numbers
  • Fractions, decimals and percentages
  • Units, areas, volumes
  • Money!

You will need to do your own answers until I get near my scanner. I wanted to show standard methods in these questions. I’m thinking of giving homework broken down into 10 or 20 minutes a day next year.

Classifying Moodle courses http://bodmas.org/blog/ilt-ideas/classifying-moodle-courses/ http://bodmas.org/blog/ilt-ideas/classifying-moodle-courses/#comments Fri, 12 Jun 2009 21:37:52 +0000 Keith Burnett http://bodmas.org/blog/?p=802

Just a way of looking at Moodle courses that Alan Staley described during a Moodle User Group meeting some time ago. I’ll be working this one up for next year’s technology supported learning course.
