My 6 year old is in kindergarten in a school where reading and writing is the main focus for her grade and I'm happy with the differentiation she is receiving in reading. However, they are just barely now touching the subject of math (numbers, counting, etc...). and the teacher won't differentiate like she does for reading because she feels that the kids will later end up with gaps in their math concepts. So we just started doing some math at home since they aren't really challenging her at school. We are currently working on double digit adding and subtracting and counting money. She's not struggling with it at all and is really enjoying doing workbooks, her words exactly "This is fun!". She went through a 1st grade math book in one sitting (granted it wasn't anything super thick).
So I'm looking for recommendations for math workbooks (looking to buy online but we also have a teacher's store nearby I can shop at) to do at home to challenge her more. And how do I determine what level book to get her?
FWIW I've heard that when they get to 1st grade they differentiate for math so I'm hoping this won't be a problem next year.
