It’s called Elmo Loves 123s, and was released on the App Store over the weekend for iPad. Aimed at younger children, it focuses on the numbers 1-20 with a mixture of songs, videos, digital colouring and games.
There’s a lot to it as well: 60 vintage video clips from Sesame Street on TV, 60 colouring pages and a number of games for your children to play. The app follows previous release Elmo Loves ABCs, in which he did a similar thing for the alphabet.
Elmo Loves 123s costs £2.99 on the App Store, and is iPad-only.
