Teacher's December countdown: 14 cards with read-aloud audio
Fourteen school-day countdown cards on Seedream 4.5 plus a 700-character read-aloud for each cost $1.26 in total on Sume.
A teacher can make 14 daily countdown cards for the school days from Tuesday, December 1 to Friday, December 18, 2026, each with a short read-aloud, for $1.26 on Sume: $0.70 for the images and $0.56 for the audio. That is nine cents a day for something students open in a learning platform or on a classroom screen.
The set has one card per day and one narrated audio file per card. It needs no video render, which keeps the price low. It also suits classrooms where devices play audio but captioned video is awkward to deliver.
Counting the days and the cost
Weekdays from December 1 to December 18: four in the first week (Tuesday to Friday), five in the second and five in the third, 14 in all. Adjust the count to your own district calendar; many schools break earlier or later than the 18th.
Cards: Seedream 4.5 is $0.05 per image on Sume, so 14 cards are $0.70. Audio: a 700-character read-aloud is $0.03325 at $0.0475 per 1,000 characters and bills as $0.04 per job; 14 jobs are $0.56. If you also want a two-take choice for each card, double the image line to $1.40 for a $1.96 total.

Classroom practicalities
Keep text out of the generated image if you can. A picture with the day number painted into it is a spelling risk across 14 images; add the day number and the activity text in your slide tool or LMS instead, and use the image for the scene only. For young readers, the activity should be in the audio and in your own typed text, so the card never relies on AI-rendered lettering.
Check the read-aloud for pronunciation of students' names, vocabulary words and any foreign terms before you run all 14. Text to speech takes a language field and a voice id; keep one voice for the whole series so it feels like one narrator. Tell students the voice is generated.
Stay within your school's rules for student data and for AI tools. This workflow uses no student images or names, and that is a deliberate choice: the cards use made-up scenes and your own activity text.
If you want one family-facing version, the same 14 audio files can be played in a parent newsletter. Add the activity text under each card in the languages your families read; the image and the audio do not need to change, and the 700-character read-aloud can be re-run in another language for another $0.04 a day.
