What's a Rekenrek? Good question! It's basically an abacus that we use in first grade to help us count, add, subtract, and make number sentences. A Rekenrek makes it easy to see groups of ten and five, which are the building blocks we use in math.
Today we made our very own Rekenrek bracelets with two groups of five. With the bracelets we were easily able to find all the different combinations to ten. There are a lot!
An easy was to see all the combinations to 10--a staircase!
HAPPY BIRTHDAY MARY! Thanks for sharing cupcakes with us. We hope that 7 is just spectacular.
