URBrainy is devoted to supporting learning of maths and English (though they seem to lean more heavily into the maths side of education). They provide a rather exhaustive list of worksheets and printable activities covering both topics, and provide frequent updates to their resources. Their materials cover KS1 through year 6 for maths, and KS1 through KS3 for English. URBrainy offers a 7 day free trial during which you can print up to 5 resources. After the trial period, a subscription is necessary to maintain access to resources. Subscribing costs £6 a month, £30 for six months, or £48 for a full year.
