Skill Sharpeners Math
A colorful collection of varied practice activities at each grade level to reinforce your basic math instruction. Each book has ten units with different themes, spiraling through skill strands. Every practice page has a sidebar notation to help you identify its targeted skill. Coverage looks pretty comprehensive. If you are using a more hands-on approach, you could use these to reinforce daily lessons. Otherwise, you might use the assessment tests at the end of each unit diagnostically, using practice pages for remediation where your child has difficulty. Some test questions are in standardized test format which might be a plus if your child hasn't had much exposure to this format. These seem like lively, appealing books that would make math practice more motivating.
