## Reflection: Complex Tasks Odd or Even - Section 3: Practice the Concept

Once the students have a good understanding of how they could look at the ones place in order to determine if a number is odd or even, I like to take that understanding and build off of it.  I write a three or four digit number on the board and have the students turn and talk about how they think they could determine if the number is odd or even.  The students should be able to apply what they have learned about looking in the ones place of a number, no matter how many digits, to make that determination.  It is important for students to be able to relate concepts that apply to all numbers, to  numbers that they may not always encounter in second grade.  These larger numbers allow you to see who really understands the topic.

Use Your Understanding and Build Off of It!
