2. From the beginning of the 2nd grade French Math curriculum (worksheet from the Professeur Phifix website):

Is everyone using the equivalent of Singapore Math but the U.S.?

The Investigations worksheet is a simple, rote addition of 10 to multiples of 10 to 90. The French worksheet is a much more challenging addition of numbers that sum to different powers of ten, with directions to color different sums in different colors (in a way that helps keep many children engaged)--very similar to a several 3rd grade Singapore Math worksheets.
