[Optional] Scratch Challenge #1: Add all the counting numbers from 1 to 1000. What is the sum?
HINT - Use a strategy: “simply the problem first”: 1. Try adding all the numbers up from 1 to 10 using a pencil and paper. 2. Code a Scratch project to do that, too. 3. Expand your Scratch project to add all the numbers from 1 to 100. 4. Expand it further to add the numbers from 1 to 1000. More ideas: Change your project and more open. Ask the user to pick two numbers - a starting number and an ending number. Code Scratch to find the sum of all the numbers from the starting number to the ending number.
