I've got an 8yo so in year 3? (Not in UK). We've been doing experiments with rubber bands, old CDs, balloons, felt - any crap. Watching what happens with ice. Weighing a full yoghurt and then empty yoghurt to see the difference (can calculate the weight of the pit), weigh ice let it melt weigh it again - any difference? Weigh microwave bag of popcorn, cook it, weigh it again - what's the difference? Etc.
We made a lollipop stick catapult (or tape a spoon to a loo toll for leverage) and flung things like Lego head, paperclip, corks, smarties tube lid, key etc to see which went furthest and write down the results. Nothing to do with schoolwork (which has been quite boring).
No worksheets. Lots of helping me cook, helping me clean (squirting water in the window, old towel to wipe it off - "more fun than Minecraft" apparently
). Blanket forts.
DS made a mission impossible set up by winding wool around chairlegs for laser beams, putting pegs on the floor like mines, fishing sharks, dinosaurs etc any plastic animals, chairs to climb under/over. Huge hit. Took all morning, several attempts to get it perfect, the we videoed it and whatsspoed to family and his mates.
Really simple stuff, lots of hugs, lots of relaxed laughs - we're all stressed as fuck WFH, no garden, only allowed out to walk dog (Spain). DS hasn't been out since March 14th and he's missing his athletics. We WhatsApp friend and family a LOT, almost two hours/day chatting 20mins here and there.
Give yourself a break. Your children need food, love, tranquility. We're about to enjoy a floor picnic lunch! The dog will love us
