Conclusion and Appendix

Concluding Remarks

The bar can be a valuable representation to enable children to represent problems in such a way that the mathematical structure is exposed.

This enables pupils to ‘see’ the problem clearly and to then recognise the strategy they need to solve the problem. The appendix contains sets of problems for each key stage for you to try with the pupils you work with.

Appendix

These problems have been tried and tested in a school for the year groups specified; however you may wish to use them more flexibly for different aged children than that specified.

Thank you for these ideas and resources. I will be trying these with my Upper KS2 lower group. Exciting!

I have always been an advocate of "draw it" to make sense of problems and we use the FDP R % P approaches. Good to see you spreading the word.

I do have reservations about the first +/- image with the total amount bar over the two parts below. Tried it out with some KS2 support groups and they found it confusing as opposed to just a bar split into 2 parts. Any thoughts? Experience of using it with ks1?

Great set of problem questions....thanks.

We're finding higher success rates for pupils that use the bar method.

I have been increasingly using these ideas with my post-16 resit GCSE / Functional Maths students, since introduced to them by Fiona Allen.
