For the parent at the kitchen table
The water cycle, the parts of a flower, how a plant drinks, the solar system, the parts of the ear, a simple circuit: the diagrams come home every week, and explaining them from memory is hard. Upload the page and you both get a calm, clear explanation of the exact drawing in the book, one part at a time, with arrows coming to life where things flow.
Why it helps children
- It follows their book. The video is made on the homework's own picture, so nothing is confusingly different from what the teacher showed.
- One thing at a time. The camera goes to each part as it's named and the rest dims, so a young reader isn't lost in labels.
- In the language you speak at home. The book may be in English while you speak Urdu, Arabic, Hindi or Spanish at home; the video can explain it in either.
- They can watch it again. Before the test, without you having to explain it twice.
A tip
Ask for the level you need: "Explain the water cycle for a 9-year-old" gives simpler words than "Explain the water cycle".
How it works
- Take a photo of the homework pageThe diagram should be clear and fill most of the photo.
- Ask your questionPick Diagram to video, add the photo, and say who it's for: "for a 10-year-old".
- Watch togetherIn about two minutes you get a narrated video of that exact picture.
Questions
Is my picture redrawn?
No. The video is made on the exact picture you upload, so every label matches your source. Only the camera, highlights, labels and moving dots are added.
Which languages?
Eleven: English, Arabic, Urdu, Hindi, Spanish, French, Portuguese, German, Italian, Russian and Polish. Narration, captions and labels are in the language you pick, even when the picture is in English.
Is it suitable for young children?
Yes: say the age in your question and the explanation uses simpler words. As with anything online, watch it together with younger children.
Is it free?
You can try it free with a Google sign-in. Students and teachers who sign in with a school email (.edu, .ac.uk, .edu.pk and the like) get ContentRoof Pro free.
