Reflection: ELL Students Estimating Local Rainfall - Section 2: Make Sense of Our Estimates

 

This student recalls that when we have worked with lists of estimates before we have ordered them and then found the median, mode and average.  I have done this with them as an extension.  This is no longer a third grade standard for very appropriate developmental reasons.  I have had them go through the  steps with me in several science lessons:  record the estimates or data, order the values, find the median, find the mode, and find the mean/average.  Those are several different ways to attach meaning to a data set that also come attached to vocabulary that is confusing for both native speakers and bilingual students.  My initial question (prior to the hints) was not sufficiently scaffolded so she tried to apply what she knew in an attempt to answer.

When I teach out of level content, such as mean, median and mode, it's essential that I provide support for all students, especially those who are learning in their second language.  I save my anchor charts, so I put up the visual definitions for mean, median, and mode again!

Estimating Local Rainfall

Unit 2: Seasonal Weather
Lesson 8 of 10

Objective: Students will estimate the amount of rainfall that will collect on a rainy day. They will work with inches and practice different ways to use units of measure and analyze data.

Big Idea: In order to understand scientific measurements and estimates, the values need to be made in or changed to a common unit of measurement.

3rd Grade Math » Going Batty Over Measurement and Geometry
Big Idea: Many students create bar graphs and can explain questions like "more than" and "less than", but are not accustomed to actually gathering the data and building the graph from the ground up. This engaging lesson requires students to do all of the above.
