Reflection: Penny Flip - Section 3: Center TIme

 

There are three videos in this section's resources.  The first video, entitled Three Columns: Using One Column To Figure Out the Other.  This is an example of a student using an existing column of 10 to figure out how many more cubes needed to be added to the current column.  The students is not secure with his complements of 10 and is still relying on counting on from a set number.  

 

The second video, entitled Student Decomposing A Number, is an example of a student combining one number to another by decomposing it into two smaller numbers.  The student had three coins and needed to add four more.  She had the problem 3+4.  She said she saw it as 3+2+2 and knew it was seven.  

 

The third video, entitled Demonstrates Use of Known Fact, is an example of a student using a known fact. He  did this by identifying one of the addends and realizing that the other had to be a certain number.  In this case he knew he had one so the other had to be 6 in order to make seven.
