Smartboard Lessons - Rekenreks for Building Math Number Sense K-1

Here is the next set of Smart board lessons created from:  “Number Talks Helping Children Build Mental Math and Computation Strategies. These lessons include an increasingly popular visual math model, called the “Rekenrek”. 

The Rekenrek is a math rack that provides a visual model to help develop strategic reasoning. It is a powerful manipulative model for young learners. The Rekenrek (developed by mathematics education researchers in the Netherlands) combines the strengths of other manipulatives (e.g., number lines, base-10 blocks, counters, etc.) in one easy to use tool. 

The 30+ daily rekenrek lessons provide multiple opportunities for your students to work with and visualize numbers in a variety of combinations. A work mat has been included in the Smart board attachments for classrooms that do not have actual rekenreks for students to use. Also, at the end of each document is a link to an online supplier of this math tool that I used to purchase my own class set of rekenreks.

All Smart board lessons provide a lesson plan to facilitate direct instruction and follow-up activities, as well as supporting website resources, and activities links in the resource section. In the resource section, you will find links your students can use in the computer lab for follow-up practice.

The next set of lessons that I will upload for you will focus on using Tens-Frames to help children build their visual and mental math skills. Feel free to request more information or send questions. I would be happy to respond.  For anyone who is unable to open Smart Board documents, I will be creating these in power point as soon as I have completed the Smart Board Lessons.

I will be uploading power point lessons of these same smart board lessons for classrooms that do not have Smart Boards when I have completed them. Again, if you have an questions, suggestions, or comments, feel free to contact me.
