# 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

I would love to know if anyone can prove the impact that Bar modelling has . Please share if you can. ~:~0

Thank you for this concise and practical resource on Bar modelling - exactly what I need to deliver my INSET after half term!

Just what I need to share with my colleagues at inset, thank you.

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?
