Reflection: Continuous Assessment Expanded Form: Stretching that Number Out from Real World Text - Section 3: The Lesson


I like to point out in lessons that we make common mistakes when we stop thinking about what the meaning is of what we are doing with numbers. I think it is important for students to understand that mathematicians have to be careful and think with every step.

I see that my students have a hard time remembering to expand the entire number when we get up in the ten thousands place and above. I was hoping the Slinky would be a good visual, because when students forget, I can use it to bunch up a spot on the slinky  and hold it so they can see their number looks like that; not stretched all out. I was continually assessing as I taught the whole group lesson, looking for anyone who was stumbling and making this common mistake. However, it turned up in their practice. This Student sample in notebook   clearly shows how easily they forget and that practice is necessary for them to achieve this. Because I saw these mistakes in their practice in their notebook, I created a chart for them to use in the next section.

Expanded Form: Stretching that Number Out from Real World Text

Unit 11: Place Value
Lesson 4 of 14

Objective: SWBAT read and write multi digit whole numbers less than or equal to 1,000,000 in expanded form.

Big Idea: Students practice a "Number Hunt" from non- fiction text and use those numbers to create expanded form and deepen understanding of the meaning of a "value" as they see multi-digits from real world texts.
