Help your student become a(n) Serial Orderer to 6+ (Length)
Activities challenge children to put 6 or more lengths in order. Discussions, careful addition of new lengths (and lengths that are not easy to "see" are different) challenge them to understand that lengths can be only a little bit different, but it is possible to find the shortest, then the very next longest, and continue to order the entire group. They are asked to use a similar logic to insert a length into a series--it must be longer than all lengths to one side of it, and longer than those on the other side.
