KS1 Program solutions table
A table showing the best solutions to levels 1 to 16 of Rapid Router.
KS1-S1
• Understand that an algorithm is a set of instructions in a particular order
• Create a set of instructions to navigate a simple route, using move forwards, turn left and turn right commands
• Follow a set of instructions accurately
• Record instructions accurately
Getting started
KS1-S2
• Build a simple sequence of instructions for a simple route
• Use the term algorithm
• Understand that a computer follows instructions called code
• Begin to debug a simple program
Solutions
Can you help the van get to the house?
2. This time the house is further away.
3. Can you make the van turn right?
4. You are getting good at this! Let’s try turning left.
5. Good work! You are ready for something harder.
KS1-S3
• Describe the algorithm you need to reach a destination
• Build your code using the ‘direct drive’ buttons
• Practice identifying left and right turns in the ‘bird’s eye’ view
• Begin to debug a sequence of instructions
6. Well done! Let’s use all three blocks.
7. This road is more complicated.
8. The warehouse is not always in the same place.
9. Can you go from right to left?
10. Well done! How about another go?
11. Snail maze!
12. This road is more complicated.
KS1-S4
• Identify different algorithms to reach the same destination
• Select the most efficient algorithm and create the program for this
• Begin to debug a sequence of instructions
13. Multiple routes.
14. Can you spot the shortest route?
KS1-S5
• Write an algorithm to include intermediate deliveries
• There will be buildings at one or more points on the route - children decide which route is the best
15. What if there is more than one delivery?
16. This time there are even more houses
