Ten-Frame Fill shows a target number, such as "Make 7", and your child taps counters onto a five- or ten-frame to match it. Each tap drops a counter into the next empty cell, and tapping a counter again takes it off, so an overshoot is easy to fix without a wrong-answer screen. When the count on the frame matches the target, a gentle confirmation appears and the next number is set.
It builds cardinality, one-to-one correspondence and number composition to 10 for EYFS and Year 1, using the Numicon-style ten-frame structure recommended by the EEF. A "finish to 10" mode pre-fills some cells so the child completes the bond, making the parts and whole of each number visible.
It is built by a UK SEND tutor with QTS, and is calm, ad-free and free of third-party tracking. There is no timer and no wrong-answer state - you simply adjust the counters until they match. It plays in any browser on a tablet, laptop or whiteboard for 1:1 tutoring and screen-share therapy sessions, and is free to play without signing up.
Put counters on the frame to match the number. Tap again to take one off.
