Study guide: Give, Follow and Check Instructions
Use ordered paper instructions, follow a route and test a drawing against its goal.
Ideas to explain in your own words
- Follow clear instructions in order.
- Arrange a container drawing before the marks that belong inside it.
- Follow right and up arrows one move at a time.
- Find an extra drawing instruction and test its removal.
Watch your reasoning
- The large circle comes first. It gives a place for the two dots and the smile. The house instruction belongs to a different algorithm.
- A makes the cup first. C can then place its line below the cup, and B can place its dot inside. The other orders ask for a cup location before the cup exists.
- UP reaches column 1, row 2. RIGHT then reaches column 2, row 2. A move changes only the direction named in its instruction.
- Removing the extra-dot step leaves the circle with exactly one dot and no extra drawing. Moving the extra dot outside still creates a mark the goal did not request.
A worked review example
Follow a Drawing Algorithm: To draw a house outline, first draw a square, then add a triangle above the square. The instruction above tells where the roof goes. Put Steps in a Useful Order: A, B, C produces a cup containing one dot, with one line below it. A, C, B produces the same finished picture: both later instructions still use the cup. The dot and line do not depend on each other. Move a Paper Robot: The route is (column 1, row 1) → (2, 1) → (2, 2) → (3, 2). The robot ends in column 3, row 2 after three moves. Check the Result Against a Goal: Before repair the square contains 2 + 1 = 3 dots. After removing draw one more dot, the square contains exactly 2 inside dots and no other marks, so the tested result matches the goal.
Make a practice plan
- Try the supplied lesson problems without looking at the answers.
- Compare your method with the worked examples and explain any correction.
- Use the new review cases, then complete the transfer task on paper or in your own document.
