Plus/Delta Assessment


Tip: Plus/Delta Assessment

How do I do it?
This is assessment is a quick way to assess student understanding of a lesson, unit, or concept.  Under the + symbol volunteers explain what they understand, know, or enjoyed about learning the topic.  Under the △ (“delta”) symbol, the teacher records things that students think need to change, be improved, or still do not understand. They can use individual sticky notes or share orally for a teacher or volunteer to record their responses. 

Variations & Extensions
Younger students may better understand a smiley and sad face symbol for the column headings.  Try sentence starters like: “I liked...” “I know..”  “I didn’t like...” “I didn’t understand...” “I wonder..” etc.  Add a third column heading → (arrow) for what we should do next based on what students have said they know and do not know.
