This hands-on workshop starts with rekenrek and number line applications and activities that can enrich important standards in K-5 math, and can be adapted to many teaching styles. We then explore an improved version called RekenMathLine. This dual use tool allows users to have a mistake-free connection to numbers for 1-to-1 correspondence, number recognition, operations, missing parts and more. We will explore math concepts and discuss in detail different ways to implement them into math curriculum in the form of games and activities, and even as rigorous instruction. Come learn about this powerful visual to enrich strategic reasoning in your K-5 math classroom. All attendees leave with the sample they worked on.
