The Summer Math Review series for Kindergarten through Fifth Grade is designed to be used as a review to ensure that your child is ready for the next grade level, to maintain skills over the school break, or to remediate and re-teach when mastery still needs to be achieved. While ideally the workbooks may be completed during school breaks such as summer vacation, they may be used at any time during the year for extra practice or tutoring. This is the First Grade workbook.
