Reflection: Ten Apples and Bananas - Section 3: Finding Combinations for 10 Apples and Bananas


I have included 5 different examples of student work.  No one in the class found all of the combinations of 10.  Although I wasn't looking to have students achieve this, it showed me that the students are thinking about "Flip Facts."  In other words, if there were 4 apples and 6 bananas, then there could also be 6 apples and 4 bananas.  I will take the time to introduce this to Matthew.  His work is included in the resources section.  You can see that his work is organized and he knows his compliments of ten.  However, he is not making use of structure in applying the idea that 6+4 is the same as 4+6.

Jack's work is an example of a student who is still drawing the apples and bananas.  He has now approach for figuring out his solutions other than guess and check method.  However, he does come up with 5 combinations (two are on the back of his page) and he wrote an equation for each one.

Cooper's work is an example of a student who created his combinations with cubes and drew the cubes on the paper.  Similar to Jack, his method is that of guess and check.  Cooper also found 5 combinations (the others are on the back of his sheet).  


Soren and Hannah are examples of students that I want to check back in with tomorrow.  I will do this while center time is going on.  With Soren, I will set up her 6+4 combination with cubes and then ask her to find other combinations.  I want to see how she proceeds and guide her from there. Hannah is someone who still needs help with her organization and ability to record what she is thinking.  I had observed her during the work time and she had the right idea but lost her focus and stamina when she needed to record what she did.  

*All of this work in labeled by name in the resource section.
