Comparing and ordering numbers can be such a tricky concept. I made this center to review lessons that go along with Go Math Module 2 but this can easily be adapted to go with your curriculum.
It includes 16 different colored comparing number mats ( 8 greater than and 8 lesson than). There are 3 different levels of cards in standard and written form (tens, hundreds and thousands up to 1,999.) The comparing numbers mats and the number cards are ink friendly and can be printed onto colored paper to brighten them up. An answer sheet is provided but not necessary to use.
If you have any questions please let me know and I'll be happy to help.
