Week 8 - Programming a Model (F-2)

Computational Thinking Skills - Algorithms (From the Australian Curriculum)

• Follow, describe and represent a sequence of steps and decisions (algorithms) needed to solve simple problems [ACTDIP004]. 

Activity 1
To give directions to a visually impaired student to get from the classroom door to the teachers desk, by only using the words forward, backward, left, right.

Steps:

1. Take 5 big steps forward
2. Take 5 big steps left
3. Take 3 little steps right.

Activity 2

Directions that can be used to make toast with Butter and Vegemite.

1. Grab bread loaf off bench. 
2. Undo bread tie.
3. Grab 1 slice of bread out of packet.
4. Put bread tie back on and place loaf back on bench.
5. Turn toaster on at wall.
6. Place slice of bread in toaster and push lever down.
7. Go to fridge and get Butter and Vegemite out and place on bench.
8. Open draw and get a butter knife and put on bench.
9. Open cupboard and get a plate and place on bench. 
10. Once toast has popped up, grab toast and place on plate.
11. Open butter, pick up you knife and get amount needed and spread on toast.
12. Open Vegemite and get amount also needed and spread on toast.
13. Place knife back on bench.
14. EAT TOAST!

This algorithm is very clear and follows the curriculum that I have mentioned at the start of the activities. To make easier for younger students that can't read, a diagram can be used to explain directions.
