Pencilhop Unlock

Practise first, then open the site. A parent picks sites; a short times-table or number set opens each one for a while.

Practise first, then open the site. A parent picks the sites that should wait. When a child opens one, Pencilhop Unlock shows a short practice set instead: times tables, adding, taking away, number bonds to 10, or a mix. When the set is done, the site opens for the time the parent chose, then locks again. What a parent sets - Which sites wait for practice - The kind of practice and which times tables - The lowest difficulty: Easy (within 10, up to ×5), Medium (past 10, up to ×9) or Hard (up to 100, up to ×12) - The fewest questions per set (5 to 20) - How long a site stays open (5 to 60 minutes) - How many unlocks a day - A PIN, so only a parent can change settings What a child sees - First, a choice of difficulty and how many questions: harder or more is fine, easier or fewer than the parent's setting is not - One question at a time with a big number pad - A red circle for a right answer; a wrong answer comes back at the end of the set - "Right first time" at the end, then a button back to the page they wanted Parents also see a 14-day history of sets, unlocks and answers right first time. Private by design: everything stays in this browser. No account, no analytics, no ads, and nothing is sent anywhere. Removing the extension deletes it all. Honest limits: a child who can remove extensions can remove this one, and private windows are covered only if you allow the extension there. It does not filter content by category; it only asks for practice on the sites you list.
