## Reflection: Connection to Prior Knowledge Interpreting Data - Section 1: A Picture is Worth a 1000 Words

Many times when we think about connecting to prior knowledge, we think about knowledge gained in previous grades.  At this time of year, connecting to prior knowledge also refers to the lessons learned in fifth grade as well.  When presenting students with the line plot that included mixed numbers, I let their prior knowledge lead their thinking, not my direct instruction.

It was rewarding to hear many of the groups dive right into interpreting the line plot with out any hesitation.  They seamlessly recognized that each like between whole numbers represented 1/4.  Some students made notes on the line plot to help with their discussion.

When one student was challenged with determining the fractions on the line plot, she and her peers had a mathematical discussion that was more rewarding than the students who dove right in.

"At first I thought that the fractions were 3rds because there were 3 lines in between the whole numbers.  Then I knew I must be wrong because I counted it out to show the others what I was thinking and I had 32, 32 and 1/3, 32 and 2/3, and then 32 and 3/3.  I know that 32 and 3/3 is the same as 32 + 1 and that makes 33.  So I knew something wasn't right.  Then I tried 4ths like the others were thinking and that made more sense."

When students discuss their reasoning with one another, they extend their understanding.  Making discoveries together is more meaningful than being told.
