My school uses Saxon math for the curriculum. They threw out the kindergarten curriculum and instead have started all kids on the 1st grade Saxon math curriculum. I see that you are from Texas - I was actually born and raised in Texas and we actually moved from there (and from an excellent school I might add).
The advanced math that the kids are doing at this new school looks like this: K is basic addition/subtraction/comparison, double digit addition/subtraction, word problems, graphs and diagrams, fractions, telling time, line of symmetry, recognizing coins/value, numbers 0-100, comparing greater than/less than, congruent/not congruent. 1st is more double digit addition/subtraction with borrowing, more word problems, more fractions, multiplication, comparing numbers, finding area and perimeter, geometric solids, measure using centimeters, etc.
Both the principal and the board president stated that they were accelerating the curriculum due to the CogAT test. I will also note that we have an older elementary daughter (straight A student) and so this is not our first go at school. In other words, we have a picture of what "normal" looks like and this certainly isn't it. This is definitely advanced compared to what is normally taught in most schools. I am just puzzled as to why they would advance math just for the CogAT test. I also know that they are obviously advancing it so their test scores will be higher. Problem is, they are not grouping kids at all to challenge those who need challenge, or to help those that need help. They tend to pull kids out of class that are struggling which I hate. Talk about a stigma. Principal is very against grouping kids and will not hear of it.
