Revisiting 10s and 1s

Students are learning a variety of ways to represent numbers.  We are working on visualizing numbers in our heads and moving beyond the numeral.  I might say visualize 42, can you think of a way to represent 44 other than a 4 and a 4?  We are working towards seeing base 10, (4 tens and 4 ones) or 4 full tens frames and another that has 4 more. Here students used a blank 100s chart to share their ideas. 


These students all had the same idea but they did not look the same on the 100s chart.  The discussion of: Who is right?  Can more than one person be right if these do not look the same?  What does that tell us?  

It was a great day of making connections and shaping our thinking by using our peers to talk with, problem solve and challenge.
