RainbowFish Portfolio is an easy to use digital platform designed to help instill creative confidence in students in primary and middle school across India. This unique Digital Portfolio App allows Parents and Students from Partner schools to maintain a digital portfolio to showcase their artwork and share the joyful imagery with their friends and family. It is an important part of the entire creative digital platform created by RainbowFish studio to help schools provide the highest quality of art education to students from ages 4 to 14. The RainbowFish Portfolio archive is a wonderful way for our students families to share their progress from story-led art explorations in Kinder years to using art as a way to learn about the natural world, cultures and more in Primary school and later as they learn to use art to express themselves, unravel their feelings and as a tool for creative problem solving in Middle school. Parents and students can also view the online exhibitions of the child’s entire class’s response to any assignment. Its almost like being able to walk down a corridor in school and see the works on display outside the classrooms – but all available from the convenience of your own home. At RainbowFish we use this robust system to provide quality art education to thousands of students everyday though a network of excellent and committed educators in our partner schools across the country. As a parent or a student from an RF partner school, you are invited to – - Take picture of your child’s artwork or your own artwork if you are a student - Adjust the picture using simple tools provided crop, rotate etc till you are satisfied - Upload each artwork individually to your child’s e-portfolio - Share the link to view the artwork via whatsapp, facebook or email with friends - View an exhibition of the entire class’s work on the same theme - Take a trip down memory lane and view your child work from previous years - Read encouraging comments from your child’s art teacher Note: You can sign up to this app if your child’s school has subscribed to RainbowFish art program.

India's first AI Reading Coach for kids. Hears every word your child reads. Teaches what they miss. In Indian English. Your child reads a real storybook out loud, from a library of 100+ levelled stories. ZigZu listens to every word. The moment they get stuck, it stops, breaks the word into its sounds, and has them try again, the way their school teaches it. Built for ages 4 to 8: Pre-K, Kindergarten, 1st and 2nd grade. Free for 7 days. No payment needed to start. WHAT MAKES ZIGZU DIFFERENT Most reading apps show your child a story and hope. ZigZu actually listens. It follows every word your child says out loud, in real time, and it knows the difference between a word they read and a word they guessed. That is the part a busy parent cannot always catch, and the part a class of forty never will. HOW IT WORKS 1. Your child opens a story and starts reading aloud. 2. ZigZu listens to every word. 3. Stuck on a word? ZigZu teaches it back, sound by sound. 4. Stickers, daily streaks and progress your child can feel. PHONICS, THE WAY YOUR SCHOOL TEACHES IT The same method Indian English-medium schools use, whether your child's school follows Jolly Phonics, Letterland or its own programme. - All 42 letter sounds, with audio - Blending, c-a-t into cat - Decoding words nobody has taught them yet - Sight words, the ones that never sound out - Indian English pronunciation throughout NINE READING LEVELS, ONE STEP AT A TIME 1. Starting Reader. First sounds: s, a, t 2. Emergent Reader. Short vowels: cat, pin 3. Beginning Reader. Letter teams: sh, ch, th 4. Developing Reader. Blends: str, pl, nk 5. Transitional Reader. Vowel teams: ee, oo, ai 6. Fluent Reader. Magic-e: cake, bike 7. Skilled Reader. R-controlled vowels: car, bird 8. Expanding Reader. Gliding vowels: coin, cloud 9. Independent Reader. Longer words: rocket, jumping Your child moves up when they are ready, not when the calendar says so. WHAT YOU WILL SEE AS A PARENT The Parents section shows the words your child read cleanly, the ones they missed, the stories they finished and the sounds they are working on now. You know what to practise tonight without sitting through the whole book. If a book feels too easy or too hard, you can change the level yourself. SAFE, AD-FREE, KIDS-FIRST - No ads, ever - Nothing is ever sold to your child inside a reading session - No chat, no social features, no links out - Works on older iPhones and iPads You can hand over the phone and walk away. WHAT PARENTS ARE SAYING "Can I do ZigZu instead of YouTube today?"
