What Do These Graphs Mean?

Persistent gap in academic achievement
between Caucasian students and those from
culturally and linguistically diverse groups:
Many teachers are underprepared to make content
comprehensible for ELs.
Few teachers trained to teach initial literacy or content-area
literacy to secondary ELs.
ELs are tested in mathematics and reading under No Child
Left Behind; and in 2007-08, tests in science have been
added to the battery of assessments they must take.

mathematics
Language production patterns
Develop language within mathematics
Vocabulary building (enrich)
Clarify the academic language
16
What is Presently Being Taught




Math in Primary grades consist of numbers, place
value, addition, subtraction, and multiplication with
whole numbers.
Intent of instruction is to make the operations
conceptually familiar, automatic, and accurate.
Math in Intermediate grades consists of
multiplication, division, decimals, fractions, ratios,
proportions, and percents. Some measurement
and geometry.
Graphing, probability, and statistics and use of
calculators are introduced.
17
What is Presently Being Taught
…….continued




The math curriculum develops students’ ability of
understand concepts through a variety of problem-solving
experiences with manipulative materials or pictorial models
prior to working with abstractions.
A foundation of basic facts and skills as in addition and
subtraction, through understanding a concrete model of the
mathematical operation.
Computational skill is developed through practicing the
procedure under a variety of circumstances.
Problem solving strategies are developed by applying
factual information to realistic problems in a variety of
different settings.
18
Actual Class Instruction


Middle school teachers spent 70% to
75% teaching skills in addition,
subtraction, multiplication, and division.
Of the time is spent on skills
development, half was spent developing
conceptual teaching and the other half
was spent on teaching problem-solving
using story problems.
19
1. Learning Atmosphere &
Physical Environment

A caring classroom atmosphere of mutual respect and
support is facilitated by the teacher who:
 Knows each child as an individual,
 Embraces languages, customs, and cultures of ELL
students,
 Provides culturally rich learning materials,
 Encourages self-expression and provides positive
recognition,
 Builds student confidence and esteem,
 Fosters an emotionally safe environment that allows
students to feel secure and to take risks.
20

2. Instructional Practices



Instructional practices foster cooperation
and collaboration.
Concepts are presented accurately,
logically, and in engaging ways.
Multiple representations incorporate
mathematics learning levels: concrete,
semi-concrete, and abstract.
22
2. Instructional Practices
cont.

The teacher employs student-centered instructional
practices.
 Approaches content from a concept-oriented
constructivist method,
 Surrounds students with different modalities,
 Connects new concepts to prior learning or prior
knowledge,
 Encourages students to refine and reflect about their
own work and verbalize concept understanding “in their
own words”,
 Chooses homework to optimize individual content
development,
23
 Provides extra help and resources on an individual basis.
2. Instructional Practices

diverse learning styles and multiple intelligences,
including for instance:






Frequent use of models and/or manipulatives,
Music as a motivator and anchor,
Mind maps, poster-walks, and word walls
Key vocabulary and cognates presented in different
forms,
Vivid adjectives,
Graphic organizers.
25
Graphic Organizers

events, characters, objects) and provides supporting evidence or
details
Organizers-tree diagrams, branch diagrams, webs, outlines,
comparison charts
Comparison-contrast-text comments on similarities and differences
among facts, people, events, and uses comparative adjectives and
transitional markers (e.g, “on the one hand…on the other,” “both…only
one”)
Organizers-Venn diagrams, comparisons
Chronological or sequential-text organized in a time sequence and
uses temporal markers, such as dates, prepositional phrases of time,
sequence words (e.g., first, next, then)
Organizers-timelines, story summaries

What’s Different in Mathematics
for English Learners?




Discourse structure may be vary different from
students’ previous English experience.
Grammatical forms and structures in textbooks
becomes increasingly complex.
All four academic language skills are required.
The language of mathematics is highly
specific, misunderstandings are remarkably
persistent.
28
Importance of Addressing The
Needs of English Learners
Most ELLs need 4-7 years to learn
English before they reach average
academic performance levels.
 As ELLs, they are by definition not
proficient.
 But they are tested before they are
proficient in English.

29
Specialized Vocabulary



English students may become confused with unique
terms such as addend and quotient, and terms with
specialized meanings, such as altogether, round,
table.
English learners have few cues to the meaning of
words or phrases apart from the limited and often
abstract context that is provided in the words and
symbols in the problem statement.
There are also combinations that have special
meanings, such as square root, multiplication table,
and least common denominator.
30
Specific words in mathematics single the
use of certain mathematics operations.

Addition is suggested by
the following words:

Subtractions is suggested
by the following words:
minus less less than
add and plus
difference
sum total combine
more than
decreased by

language needs.
Language used is appropriate to age and grade
level and presented in a socially meaningful
context.
Mathematics-specific vocabulary is explicitly and
implicitly taught and reinforced through repetition.
37
4. Language Practices cont….



Teachers are knowledgeable about the second
language acquisition theories and best practices.
Ideally, dual language instructional support should be
offered.
When dual language teachers are not available,
sheltered instruction should be utilized to provide
strong language support by addressing content
through ESL.
38
5. Family & Community
Involvement



Schools connect to student’s family-life by
embedding contextual experiences and skills in
teaching and curriculum.
Projects are relevant and promote family
interaction.
Opportunities are available for English-speaking
higher grade-level students to mentor ELL lower
grade-level students either in an in-school or afterschool program, as appropriate.
39
5. Family & Community
Involvement cont….



Teacher engages in frequent communication with
families
 About activities and events in which parents can
participate,
 About student progress.
Teacher utilizes services provided by a community
liaison and is knowledgeable about community
resources.
Parents are informed about the benefits of using their
most cognitively advanced language at home.

6. Assessment of Student
Learning



Classroom assessment is designed to foster
student success.
Assessment methods allow students frequent
opportunities to demonstrate mastery in a
variety of ways.
Various assessment techniques are used to
measure student understandings.
41

Learning cont….



Grades are oriented to promote and
emphasize valid step-by-step logical
reasoning processes.
Assessment data and results shape
instructional planning.
Flexible time allotments are given to
demonstrate concept mastery.
42
How to Teach Problem-Solving Steps





Understand the question-teach students to understand
the problem through elaboration and imagery.
Find the needed information-Help students use
selective attention to find needed information.
Make a plan-have students identify the operation and
what the problem calls for, then choose a plan (write a
number sentence, identify parts of the problem, work
with a peer, make a table, make a list).
Solve a problem-Students write out the steps of the
problem and solve it, using cooperation to review the
steps they have taken.
Check the answer-Students use a variety of
approached o verify that their answer makes sense.

Finding a Suitable Definition
Activity 1
1. Show Slide 1 and have students find a
suitable definition for a pentomino.
2. Write their definition on the board or on chart paper.
The formal definition means little to English
learners; however, students can develop their own
definitions using Slide 1 through group discussions
and consensus. This helps in giving ownership of
the definition to the students while disclosing only
two of the twelve pentominoes.
A Suitable Definition
They should come up with
something that includes the
following information:
A pentomino is a two-dimentional
shape made from five congruent
squares such that each square has
at least one of its sides in common
with another square.
Finding the Twelve Pentominoes
Activity 2
1. Have students work in small groups to find the
twelve different pentominoes.
2. The new shapes should be made with five square
tiles to test their definition of a pentomino.
3. Each whole new shape should be cut out of
squared paper.
4. Each group should check to make sure they do not
have duplicate shapes by flipping, turning or
rotating similar shapes.
5. Each group will need a set of twelve pentominoes
for the activities that follow.

Fold into an Open Box
Activity 3
1. Have students guess which of their
pentominoes form a network for a
cube without a top.
2. Fold the pentominoes to check their
conjectures.
The Pentominoes that form an Open Box
F, L, N, T, W, X, Y, and Z
form such an open box.
Transferring between the second and
third dimensions is important in many
occupations such as architecture,
drafting, and design.
This activity facilitates the student’s
understanding of the process.
Exploring Symmetry
Activity 4
1. Have students place a Mira on all or some of the
pentominoes so that reflection is the same as the
behind the Mira. This can also be done by folding
the shapes.
2. Ask student if all pentominoes have a line of
symmetry?
3. Have them identify those that have a line of
symmetry and those that do not.
4. Have the identify those that have multiple lines of
symmetry.
Exploring Tessellations
Activity 5
1. A tessellations is created when a shape is
repeated over and over again covering a
plane without overlaps.
2. Ask students if they can find the pentominoes
that tessellate.
3. Have them identify those that tessellate and
those that do not.
What can you do with these 12 puzzle pieces?
You would be amazed!
(Remember, each piece contains 5 squares, so there are 60 cubes total.)
Using all 12 pieces, you can make:
1. A 6 x 10 rectangle
2. A 5 x 12 rectangle
3. A 4 x 15 rectangle
4. A 3 x 20 rectangle
5. An 8 x 8 square with 4 pieces missing in the middle
6. An 8 x 8 square with 4 pieces missing in the corners
7. An 8 x 8 square with 4 pieces missing almost anywhere
8. A 3 x 4 x 5 cube
9. A 2 x 5 x 6 cube
10. A 2 x 3 x 10 cube
11. A 2D replica of each piece, only three times larger
12. A 5 x 13 rectangle with the shape of 1 pentomino piece missing in the
middle
13. Shapes with jagged edges
14. Tessellations using a pentomino
15. Hundreds of other shapes!

What’s Difficult in Math for
English Learners?




Language Dependence in Mathematics-Specialized
terms and terms used in unique ways; syntactic
features of word problems.
Non-Linguistic Difficulties-Students must process
complex concepts and different used of otherwise
familiar terms.
Cultural differences-Cultural differences in the use of
decimals and comas, in fractions, or in the strategies
students use to solve word problems.
Instructional implications-Special procedures are
needed that enable students to test hypotheses about
language use and other potential problem areas.
Cooperative learning activities are necessary to give
students practice in verbalizing new concepts.
