119. Inequalities Trashed

My colleague Jane introduced me to ‘Tick or Trash’ worksheets and they are just brilliant!


The basic idea is you have a table with three columns. The middle column is the question, either side are the solutions of fictional pupils. I called mine Kirsty and Kyle as I don’t teach anyone with those names. One solution is correct, one isn’t. Your students must decide who is right and why. They must then decide where the other pupil went wrong.

The worksheet I’ve put together is about inequalities. It covers using a numberline, solving a linear inequality with the unknown on one/two sides and dealing with a negative. There is also a QR code linking to a short YouTube clip (not mine) on solving inequalities. Download it here. The basic colour coded answers are available too. Note: the files are in docx format.

This is an ideal activity to use with the Validator concept. I would give my peer Validator the answer sheet to refer to, but the explanations would be down to the students to gauge if they understood.

87. QR teaching

Revision is a tricky business! Everyone needs something different – it is the ultimate manifestation of personalised learning.

As you will have seen from previous posts I’m not averse to chopping up exam papers or using technology to make things interesting. I also recommend YouTube videos for different revision topics.

This week I started printing QR codes, linking to online resources, onto stickers and attaching them to worksheets/books.

All pupils need is a smartphone/ipad with a barcode scanner installed. They can access the extra material whenever it is appropriate and the alternative explanations can be useful. It also helps keep pupils on task while you are helping others.

I used QRstuff.com as you can print directly to stickers (you can download them as .png files too), however there are many other sites available. If you scan the QR code above, you can access the QRstuff site too.
