Letters & Words
Sounds, words and little stories
A path that starts with hearing the sound of A and goes on to reading "I see a cat", then to the grammar a Class 1 child meets: he, she, it and they with is, am and are. Masti says each sound, the child finds the letter on the keyboard, builds three-letter words from the sounds, meets the little words that join them into sentences, and then learns which word goes where. Each age band has its own units below, and new units are added every week.

What your child learns
By the end of this world
- Knows the letters by sound, not only by name, and can find each one on a keyboard.
- Reads and types three-letter words like cat, sun and hen from the picture alone.
- Reads a short sentence and answers a question about it.
- Uses he, she, it and they with is, am and are to say a sentence about a picture.

A real lesson: “cat, bat, rat” from Three-letter words
How one lesson goes, step by step
Masti opens with: “Cat, bat and rat all end with "at".” “Listen, then type the letters you hear.” Everything she says is spoken aloud.
Warm-up. One quick item from an earlier lesson, so last week's learning stays fresh.
Learn. Masti teaches the idea with pictures, in her own words, before anything is asked.
Try. 3 goes of Type the word, with help one tap away. Before a new kind of question, a short “Watch me first” demo shows the gesture.
Play. One game of Choose the word with the same idea.
Check. 3 goes of Type the word with no help. Only this step counts towards mastery, and a wrong answer gets an amber nudge, never a red cross.
Celebrate. Stars, XP, the streak tick and the next lesson's name.



The skills it builds
And why they matter at this age
Letter sounds
A child who knows that A says "a" can work out a new word. A child who only knows the letter names cannot. Every letter is taught by its sound first, with a word that starts with it.
Three-letter words
Cat, bat and rat share an ending. Hearing that pattern is the first step in reading: the child stops guessing from the picture and starts reading from the letters.
Typing
Typing a word letter by letter makes the child attend to every sound in it, which is exactly what spelling is. The on-screen keyboard glows the next key when help is on, and stops glowing in Check.
Sight words and sentences
"I", "a", "see" and "the" cannot be sounded out, so they are learned by sight, then dropped into sentences the child can read end to end.
He, she, it, they
The first grammar a school asks for. He for a boy or a man, she for a girl or a woman, it for one thing, they for more than one, each with is, am or are. The child picks the word for the gap in a spoken sentence about a picture, so the rule is heard before it is named.
8 kinds of practice in this world
What the activities look like
Every activity is one of fourteen kinds the whole app shares, so a child who has met one never has to learn a new screen for the next lesson.

Type the letter
Hear a sound, press that letter on the on-screen keyboard.

Choose the picture
Hear a word, tap the picture that matches it.

Type the word
See the picture, hear the word, type it letter by letter. With help on, the next key glows.

Choose the word
See a picture, pick the word that names it.

Drag to sort
Drag each card into the group it belongs to.

Fill the blank
Type the missing word in a sentence about the picture.

Read and answer
Read three short lines, then answer a question about them.

Sequence order
Put the pictures in order: first, next, last.
By age
The same world, pitched to the child
Explorer 3–5
