I recently purchased this resource for my daughter, and it has been very helpful. The explanations are clear and easy to follow, breaking down each step of simplifying expressions in a way that makes sense. She liked that the practice problems started easy and then got a bit tougher, so she didn’t feel overwhelmed. Overall, it’s been a great extra support for her homework, and I’m glad we got it. Definitely worth it if you want something simple and effective for practicing math at home.
