Hi Tanka,
Our kids also had a hard time doing math sheets after a full day of school at this age. Do you think your teacher will be open to bringing some level-appropriate math sheets to school so your daughter can work on it independently during math time at school?
For us, we send in only review materials.... It is not moving forward, but we thought reviewing and retaining is better than forgetting.
Another approach (we are still waiting for an answer from school) is considering an online math courses if your child's school has computers that she can use and you think she can be an independent learner.
Just a couple of thoughts....
