The scoring table is at the top. It says how many points a route is worth - and it does not rise evenly - 1, 2, 4, 7, 10, 15.
Below it there are two routes made of several legs. Look up each leg in the table and add the points.
Both routes are exactly the same length. Still one is worth more, because long legs pay off better than many short ones. Check off the better one.
For parents
What does this exercise practice?
Looking something up in a table is different from calculating it, and both are needed. Because the table does not rise evenly, the child cannot compute the answer and really has to look - and notices that "same length" does not mean "same value".
Common pitfalls
Adding up the lengths instead of the points gives the same number for both routes and makes the task look broken. Look up first, then add.
How to practice at home
Write your own scoring table on a sheet of paper that rises faster than the length - 1, 3, 6, 10 for example. Then build two routes of the same length and score both.
