I think Op is being rather defeatist.
Are you a person who immediately sees an opportunity and is glass half full, or someone who instantly sees the difficulties and isn’t interested in finding a way forward?
You do have a garden....you have outside space. It might not be grassy or have lots of planting but you do have outside space. And of course you can venture further into a wider range of outside space.
Is your objection the fact that there are activities which benefit most from being done outdoors or that you are trying to work at home and so helping with home schooling if any type is tricky? Do you have suggestions of workable alternatives that the school can provide or are you just generally feeling pissed off at life and Covid and so want to suggest you are being discriminated against because if a lack of garden.
Life generally isn’t equal. It’s always been the case that some people have bigger houses or garden or more money or whatever. Those with bigger houses will always be more likely to have more room for their kids to have their own bedroom, to have more toys out all the time, to have a desk, to have separate space for homework, for parents to have their own home working space. Schools work very hard to give everyone opportunities and actually to level-up and they try hard to produce take that all can do.....but some families have more resources and access to facilities which will always make it easier. For example, some families have parents who do t work and so can help with home schooling more. This doesn’t mean the school is wrong to provide activities such as this and nor is the woodland trust.
Don’t we all have to recognise these are difficult times and to try to do the best we can in our given circumstances and have a can-do attitude?
Some people will be complaining to school all the time. Ther will be complaints about uniform lists, about lunch rules, about homework, about school trips, about discipline policies......they want to be victims in everything and see the school (or other organisations) as the enemy who are out to get them and make their lives harder. Other people in exactly the same circumstances who might find some things a struggle see opportunities and make most things work for them and their kids.
Guess which kids do better?
I just think that some people want to complain about every single thing and find reasons why it doesn’t work for them. And such attitudes are quickly passed to the kids too. Such a shame.
