Today, we are working towards… • Use a ‘Design Notebook’ to describe our ideas & feedback • Develop a Scratch Program that includes ‘procedures’ • Use timing to show output to create a dance animation You may need headphones for today’s lesson, but no music please.
Key Computing Terms IF , THEN, ELSE (selection) Output (sound, messages) Broadcast (send a message)
What Are We Creating Today? Today’s program is called ‘Let’s Dance’ In this program, we will have multiple ‘sprites’ which will be showing difference dance moves on the screen to make a well known dance. In today’s lesson, these will be simple and next lesson you will be designing this program using images of your class! The song we are using today is The Harlem Shake.
Move Up! Today’s program is called ‘Let’s Dance’ Each move that your character makes only needs to be programmed once. You can then make it perform the move by ‘broadcasting’ a message to show that move. IF ‘kick’ is received THEN THEN repeat forever (or until stop) change costume to kick wait 0.25 seconds change costume to jump wait 0.25 seconds

How Do I Plan My Program? Before you open Scratch, plan what your ‘Let’s Dance’ will do and look like. Use your Design Notebook to plan out how you will build your collage & what it will look like. In this program, we will have multiple ‘sprites’ which will swap costumes to look like they are dancing. Different sprites will start dancing at different times of the program. A copy of the images & sound used in my example are available on the X drive, or you can use your own. 8 10 11 9 13 12 14 15 7 5 0 6 4 3 2 1 mins
