## Reflection: Checks for Understanding Smiley Faces and Up - Section 1: Warm Up

The warm up today was to give me a chance to do an informal assessment on student's ability to fluently solve addition and subtraction problems. I watched as children employed strategies for doubles, partners of ten and one hundred, repeated addition, doubles plus one.

There were students who still counted each number, and there were those who employed the patterns they recognized to solve the problems. Those who can use the patterns are more fluent than the students who use less efficient counting methods.

My informal assessment gave me valuable information about which students are employing a variety of strategies, and those who are not.
