How do we solve these kind of problems please?
Jason and his friends are delivering leaflets around the local housing estates.
Jason wants to choose a housing estate where he won’t have to walk down the same street more
than once (he can pass over the same corners more than once). On which of these five street
plans is this possible?
These questions need you to first identify the type of corners/vertices as either ODD (an odd number of roads leading to that corner) or EVEN (an even number of roads leading to them).Do this for all of the road plans bearing in mind the following …
The correct route, that is the one where the same corners can be passed over but not the same road, is the one where there are 2 or less ODDvertices (corners), any more than it is not possible, so all even vertices is also possible.
Once you know how to do these, they provide an easy mark.
My daughter did 2 chukka mock exams last summer and successfully the passed her 11+ and is going to The Latymer School in September. The exams are a great way of assessing what needs to be done and getting them used to the pressure of sitting in a big hall and experiencing the feel of an exam. Certainly there was a huge amount to do in the exam but my daughter said they were much harder then the actual 11+ exam! Don't tell your kids that….they are really good to do and you get a chance to go through the questions on line afterwards to see where your weaknesses are.
