The Rekenrek is a tool, sort of like an Abacus designed to help students build number sense and fluency in addition and subtraction. This week the 2nd graders learned how to make and use them. Then they were paired up with a 1st grader and given the difficult task of teaching them! It was so cool to see how quickly they had them built and in use.
The first graders picked up new ways to use it and new ways of thinking. There was so much math vocabulary floating around the room I was close to tears.
Then everyone started recording different ways to make numbers in number sentences. Some stuck with comfortable addition and others went straight to abstract thinking in subtraction.
Now everyone has one to take home to assist them with homework. For more information on how to use a Rekenrek check out
The Rekenrek Site. I will put links in the math section of our blog soon.
