DAY 1 – A pandemic is spreading across an n × n grid. Each tile gets “infected” if at least two of its four neighbours are infected. What is the minimum number of infected squares required initially, so that the pandemic can eventually cover the entire grid?

Word of the day is 'smellfungus' (18th century): a habitual fault-finder; one who immediately takes offence without a second glance.

Not sure it is necessarily cruel but unless they are a secure grade 5 then I would never enter for the higher for the reasons you state

Have now added answers for the revision formula sheet. All resources can be found in the google drive. Hope you find it of some use.

I believe you should have an agreed departmental focus, spend the time jointly planning and just sharing ideas, get someone you respect from another school to add extra ideas. Having time to explore for some will be so valuable, many teachers are unaware of what is available

Such a shame hasn’t included young people studying in colleges in this campaign 😢, particularly as we serve a higher proportion of disadvantaged students aged 16-18

These prompts are designed to help uncover the process of estimating/checking answers (something that can seem harder than actually performing the calculation). Tell me if you like/don't like and what you would add/change 👍

Discussed a lesson on comparing fractions in our SMS meeting today and I scribbled an problem down. I think I quite like it. It’s a little trickier if you insist on having only solutions where the fractions are in their lowest terms.
