  • N-Tiles

  • Google Slides      
  • N-tiles are strips with 2, 3, or 5 dots used to support skip counting and early multiplicative reasoning. This slide deck contains 2 sets of slides. The first is “animated” and should be used in slideshow mode. These will automatically display n-tiles or ten frames one-by-one in structured arrangements. The second set of slides should be used in editing mode and allow the teacher to lay out n-tiles in any arrangement.

  • Sequenced Multiplication Stories - Add or subtract a group

  • Google Slides      
  • "Inspired by the book Math Fact Fluency by Jennifer Bay-Williams and Gina Kling, this slide deck consists of sequenced stories." The first story starts with a basic multiplication fact such as 4x10. The next story involves adding or subtracting a group, encouraging students to use relational reasoning to solve the new non-basic fact such as 4x9 (pictured here).
