1. Classic Errors
I similar this activity suggested past times James Tanton (@jamestanton). James asks 'Would taking classic as well as tempting errors "head-on" endure a worthwhile classroom activity as well as discussion?'. It's worth reading the responses inwards the thread. In it Cathy Yenca (@mathycathy) recommends the classic resources 'Algebra Atrocities' which is worth a look.

Grab a estimator as well as get got a learn as well as you'll run into why this is a neat chore to purpose when teaching house value. I mean value that house value is ane of the hardest things to instruct inwards Year 7 thus it's helpful to run into a expert character activity for this. Tom suggested it would also function good amongst criterion form.
