The Number Case is a key component of the ORIGO Stepping Stones K-5 Core Program. These ready-made visual models are designed to support students as they develop their understanding of number concepts in program lessons.
The Number Case is the result of research on how children develop an understanding of number concepts. These visual models work very well to support other math programs.
Each of the visual models provides coverage of grade-level appropriate concepts. There are multiple representations of number, sharing mats, numeral expanders, mix-and-match puzzles, and more. Each grade level case is packed with over 200 ready-to-use resources that save teachers time in preparing their lessons.
