approaches and solutions • Lead to further questions• Allow for finding math in everyday
situations• No key words

Framing Assessment
WHAT? WHY? HOW?
Formative Assessment
![Page 7: Stop Pulling Teeth: How to extract students mathematical thinking Deb Rosenfeld Suenita Lawrence Education Development Center, Inc](https://reader035.vdocuments.net/reader035/viewer/2022070307/551a2483550346545e8b45de/html5/thumbnails/7.jpg)
What is formative assessment?
• Assessing as you go
• Part of your instruction
![Page 8: Stop Pulling Teeth: How to extract students mathematical thinking Deb Rosenfeld Suenita Lawrence Education Development Center, Inc](https://reader035.vdocuments.net/reader035/viewer/2022070307/551a2483550346545e8b45de/html5/thumbnails/8.jpg)
Why formative assessment?
• Shows what students know and can do
• Helps teachers to: – better understand students’ thinking and
reasoning– pinpoint students’ errors or
misunderstandings
• Informs further instruction

From the classroom…
+ = 10Consider what each response
tells you about students’ thinking and understanding

Create your own Headline Story
• Think of a skill to assess
• Think of a context where it might be used
• Describe that scenario without posing a question

Recording student responses
• Student idea page:
My idea, someone else’s idea, new idea
• Snapshot of students’ responses:
Display on chart paper, take a picture, type up responses
