# Sequencing Commands micro-lesson

Do you struggle with balancing your kids’ screen time with their education? Say hello to 1Question, the app that solves this problem with a fun twist! Our app lets your child earn screen time minutes in their favourite apps by watching educational videos and correctly answering quiz questions. And the best part? You get to decide which apps to lock behind learning using 1Question.

## Learning time​

Kids learn by watching short, engaging video lessons.

When you are coding, the sequence of commands is really important. The computer follows the instructions in the exact order that they are given. The instructions must be in the right order so the program can run correctly. Imagine telling someone how to make a sandwich and giving them the instruction to butter the bread last. It just wouldn't work. The same rule applies in Scratch. The order of command is really important so the animation can work. Found a short animation. Let's see what happens. Press green flag to start. The cat’s saying it can see a fish, but I can't see a fish. Now, I can see the fish. Hmm, that doesn't really make sense. Let's have a look at the code. The cat's instructions are telling it to say, “Oh look! A fish! Yum!” before it does anything else. I wonder if we can change the sequence of the commands, so the animation makes a bit more sense and the cat says it once the fish has appeared. The fish also has some instructions. It's been programmed to say, “Please don't eat me!” but I didn't see this come up in the animation. I wonder why that is. Can you fix this problem too? Head on over to scratch.mit.edu and see if you can solve these problems.

Kids earn more screen time by answering fun educational questions.

## Recreational screen time

Kids can use the screen time minutes they earned to unlock the apps selected by their parent e.g. games, social media, streaming, etc.

## Out of time

When screen time minutes run out, kids are locked out and need to complete more learning in 1Question to earn more time.

Our micro-courses are developed and delivered by qualified educators from around the world.
