Linguistic Rich Math ClassroomResources
Mathematical Conversations to Transform Algebra Class
Gives 3 examples of conversations to help transform your Algebra classroom
Using Literacy Strategies to Teach Precalculus and Calculus
Provides examples of strategies that can be used in all math classrooms, but gives specific examples for Calculus
Language Rich Math ClassroomMy Background
Linguistics
How many languages do you speak?
Raise your hand if you are bilingual.
Raise your hand if you are trilingual.
Which languages do you speak?
Did anyone mention math?
Discuss math as a language

Linguistic Rich Math Classroom
Value of transforming your math classroom into a language rich environment
Language Rich Math ClassroomMath is a language.
Students have inexperience with reading mathematics
Reading math is different
Creating a language rich math classroom goes beyond story problems
Be sensitive to students
Vocabulary can be overwhelming
Language Rich Math ClassroomHow?
Provide clear definitions
Interact with math
Explain etymology of words
Frayer Models
Create Word Walls
Language Rich Math ClassroomClassroom Culture
Conversations and practices
Traditionally math classrooms focus on practices
Help students recognize the strengths and weaknesses of their own interpretation
Build on student ideas
Make Math come alive!
Develop norms
Language Rich Math ClassroomClear Definitions
Reduces the language barrier
Discover definitions using GSP
Discover definitions using patty paper
Write definitions using classify and differentiate
Language Rich Math ClassroomClear Definitions
Precise
Mathematical terms
Student discovered and written
Language Rich Math ClassroomDiscover Clear Definitions
Objective:
Students will demonstrate understanding of basic geometry terms.
Students will write definitions
Language Rich Math ClassroomDiscover Clear Definitions using
GSP Makes geometry come alive
Provides instant feedback
Basic sketchpad commands match the basics of geometry
Create a sketch, discover a theorem or definition
Thus reducing the language barrier
Language Rich Math ClassroomCultivate the Culture
Discuss the definitions
Place the words on the word wall as students discover definitions
Model how students should organize their definitions (My class will do on a foldable)
Provide time for students to
Pair share
Share in a square
Language Rich Math ClassroomDiscover Clear Definitions using
GSPToolbar and Toolbox Discover Point
Select the first icon with the dot
On the screen there is an arrow with a dot. Stop the arrow where you would like to place your point.
The dot is highlighted.
Select Display
Select Show label
Create another point and label it
Language Rich Math ClassroomDiscover Clear Definitions using GSP
Extensions
Ask students to continue to practice creating and labeling points
How are students labeling points?
To automatically label new points:
Edit/Preferences/Test
Language Rich Math ClassroomDiscover Clear Definitions using GSP
Construct a line
Select two points C and D
Select Construct
Select Line
Language Rich Math ClassroomDiscover Clear Definitions using GSP
Construct a Segment
Select two points A and B
Select Construct
Select Segment
Language Rich Math ClassroomCultivate the Culture
Compare the constructions to encourage discussion
Sample Questions:
How can a line have an infinite length when it is made of points with no size?
Language Rich Math ClassroomDiscover with GSP
Midpoint Select the segment
Not the endpoints (opportunity to discuss endpoints)
Select Construct
Select Midpoint
(If students are not selecting the segment then they will not be able to select the midpoint.)
Move point C.
My initial thought is________
Now I am thinking ___________because…
Language Rich Math ClassroomDiscover with GSP
Midpoint Select the line
Select Construct
Select Midpoint
What do you notice?
Language Rich Math Classroom Algebra or Coordinate Geometry
Midpoint Formula Left click to select point
Right click to select coordinates
Use midpoint formula
Language Rich Math ClassroomCultivate the Culture
How to label a segment
Measure the segment. It will show the label
My initial thought was ________________ and now I am thinking _____________
Language Rich Math Classroom Write Clear Definitions (Serra 48)
Classify your term. What is it? Differentiate your term. How does it differ from others
in that class? Test your definition with a counterexample.
Example:
A square is a 4 sided figure that has four congruent sides and four right angles.
Annotate to introduce each word
You have introduced more academic vocabulary– classify, differentiate, counterexample
Language Rich Math Classroom Clear Definitions (Serra 48)
Define the following terms:
Parallel lines
Perpendicular lines
Language Rich Math Classroom Clear Definitions (Serra 48)
Parallel lines are lines in the same plane that never meet
Perpendicular lines are lines that meet at 90 degree angles.
Language Rich Math ClassroomCultivating Conversation.
Why is it important to state that parallel lines are in the same plane
Language Rich Math ClassroomHave Fun with Words
What did the acorn say after it grew up?
Gee, I’m a tree! (geometry)
Coplanar
What other words begin with co?
Points No measure
Lines length
Planes are two-dimensional Length
Height
Space is three-dimentsional Length
Width
Height
