100 Bead String Decimal Number Line
The kids were able to find a lot of equivalent decimal and fraction names as well. Then someone started pointing out that you can multiply the numerator and denominator of a fraction by 10 and come out with an equivalent fraction. Here are some of their examples
I think this could lead nicely to the class constructing knowledge about how to find equivalent fractions. It is something we can build off of in the coming weeks.
My next idea is to use a meter stick as a decimal number line. Great way to connect metric measurement into decimals and fractions!
I will be posting more next week about how I made the 100 bead strings and how I use them in First and Second grades! Stay tuned!
