Skip counting in nines lays out the patterns fundamental to arithmetic. In these self-directed homeschool workbooks, students will internalize these patterns and pave the way to mastery over numbers. On the Frog Pond, the student is first introduced to the idea that skip counting in nines is really just counting backwards. On the Hundreds Boards, the student has the opportunity to put to practice what they learned in the Frog Pond. The boards start out easy with full color-coded guidance and end virtually unaided by visual cues. Blank and Printer Friendly Worksheets (PDF Download only) Blank Frog Ponds and Hundreds Boards are provided for exercises customized by you. At the end of this booklet are printer friendly versions of all the worksheets. Coil Binding (Print only) This workbook uses coil binding and can open flat on a desk or table and offer 360 degree rotation for easy work. Supplement For: Martian Mathematics, Level 1
