6. Why Is English So Hard? The soldier decided to desert his dessert in the desert. Upon seeing the tear in the painting, I shed a tear. After a number of injections, my jaw got number. A minute is a minute part of a day.

7. Why Is English So Hard? There is no egg in eggplant and no ham in hamburger. How can a slim chance and a fat change be the same, while a wise man and a wise guy are opposites? Did you say thirty or thirteen? Did you say two hundred or two hundredths? Did you say fifty or sixty?

8. “Even” Social register The floor is even (smooth/liso) The picture is even with the window (leveled/nivelado) Sleep provides even rhythm in our breathing (regular/uniforme) The dog has an even temperament (calm/calmado) If we share equally, we will be even (balance/igual) I looked sick and felt even worse (comparative/aún) So simple, even a child could do it (comparative/incluso)

9. Social register Got even To be even Even out Break even Not even Even-Steven “Even”

10. Mathematics register Number: even numbers (e.g., 2, 4, 36, 58) Number: even amounts (e.g., even amounts of flour and sugar) Measurement: exact amount (an even pound) Function: even function (e.g., y = 5x 2 – 3; y = cos x) “Even”

12. Mathematics Language vs. English Multiplying... English: repeated addition—larger Mathematics: larger, smaller, or neither Dividing... English: cut into pieces Mathematics: same as multiplication (dividing by a non-zero number is multiplying by its reciprocal) “Ameobas multiply by dividing”

13. Teachers learn to amplify and enrich—rather than simplify—the language of the classroom, giving students more opportunities to learn the concepts involved. Aída Walqui, Teacher Quality Initiative

14. Mathematics Content Let’s go to mathematics content. We must always begin any lesson with the mathematics content we want our students to understand. We then ask the following questions: What do we want our students to know and be able to do? What mathematics language do we expect students to know before the lesson? What mathematics language do we plan to use? What instructional materials would support the students in learning the mathematics content? How do we plan to assess what students learned?

15. Frontloading Language Proportional Reasoning Direct proportion Inverse proportion InvariantCovariation Multiplicative thinking

16. Reasoning Reasoning suggests that we use common sense, good judgment, and a thoughtful approach to problem solving, rather than plucking numbers from word problems or any problem and blindly applying rules and operations.

17. Proportional reasoning will refer To the ability to scale up and/or down in appropriate situations and To supply justifications for assertions made about relationships in situations involving simple direct proportions and inverse proportions. Proportional Reasoning

18. In colloquial terms, proportional reasoning is reasoning up and/or down in situations in which there exists an invariant (constant) relationship between two quantities that are linked and varying together.

19. Proportional Reasoning Many students who have not developed their proportional reasoning ability have been able to compensate by using rules in algebra, geometry, and trigonometry courses, but, in the end, the rules are a poor substitute for understanding. We need to get away from having students start with a/b = c/d. We need students to understand proportional reasoning, and we need to develop proportional reasoning in students by knowing how to approach proportional reasoning without using a/b=c/d.

20. Proportional Relationships Proportional relationships involve some of the simplest forms of covariation, where two quantities are linked to each other in such a way that when one changes, the other one also changes in a precise way with the first quantity. Let’s look at a couple of problems.

21. Laundry Detergent If a box of detergent contains 80 cups of powder and your washing machine recommends 1¼ cups per load, approximately how many loads can you do with one box?

22. Laundry Detergent 1¼ cups 1 load 1¼ cups 1 load 5 cups 4 loads 5 cups 4 loads 40 cups32 loads 40 cups32 loads 80 cups64 loads 80 cups64 loads The ratio of cups to loads is 1¼:1 or 5:4 In a direct proportion, the direction of change in the related quantities is the same. We say that “y is directly proportional to x” or that “y varies as x.”

23. Men Working It takes 6 men 4 days to complete a job. How long will it take 8 men to do the same job, assuming that they all work at the same pace? Think: 6 men work 4 days 1 man doing the work of 6 men all by himself takes 24 days 8 men, dividing up the work that 1 man did, take 3 days

24. Men Working In inverse proportion, the direction of change in the related quantities is not the same. We say that “y is inversely proportional to x” or that “y varies inversely as x.” # men# days# man days 6424 1 83 46 21224

25. Multiplicative Thinking Differentiate between additive and multiplicative situations and apply whichever transformation is appropriate. Process of addition is associated with situations that entail adding, joining, subtracting, separating, and removing. Process of multiplication is associated with situations that involve such processes as shrinking, enlarging, scaling, duplicating, exponentiating and fair sharing.

26. Couple of Problems If 6 chocolates cost $.93, how much do 22 cost? Guillermo can mow Ms. Rivas’ lawn in 45 minutes. Guillermo’s little brother Roberto takes twice as long to do the same lawn. How long will it take them if they each have a mower and they work together?

27. Chocolates If 6 chocolates cost $.93, how much do 22 cost? 6 chocolates$.93 6 chocolates$.93 2 chocolates$.31 20 chocolates$ 3.10 22 chocolates$ 3.41 The ratio of chocolates to cost is 1:15½ or 2:31

28. Chocolates If 6 chocolates cost $.93, how much do 22 cost? 6 chocolates$.93 6 chocolates$.93 24 chocolates$ 3.72 2 chocolates$.31 22 chocolates$ 3.41 The ratio of chocolates to cost is 1:15½ or 2:31

31. Instructional Strategy What did I do or could have done to support the language and content? Engaged you in a high cognitive demand task. Walked around and posed questions. Allowed for discourse. Allowed you to explore the why—the metacognition.

32. Discourse: Focus on an Effective Mathematics Community for ELLs Four Areas of the Learning Environment Beyond Setting High Expectations Taking Time to Listen, Observe, and Learn Understanding Individualistic vs. Collectivistic Value Systems Affirming ELLs’ Cultures in the Mathematics Classroom

33. Beyond Setting High Expectations All instructors set high expectations of their students. What practices are aligned with high expectations? What practices are not aligned with high expectations? How do you or might you align your high expectations with your practices?

34. Taking Time to Listen, Observe and Learn Listen with both a “mathematical ear” and a “personal ear.” What spaces do you create for listening to, observing, and learning about students’ personal and mathematical experiences? In the face of the many daily demands placed on instructors, how do you consistently take note of what students are struggling with personally and mathematically?

35. Understanding Individualistic vs. Collectivistic Values There are two value systems that may distinguish different ways of being, knowing, and interacting: individualist and collectivistic. “Every culture has both individualist and collectivistic values.” (Rothstein-Fisch and Trumbull) Traditionally, schools in the U.S. tended to be more aligned with an individualistic value system, which represents mainstream U.S. culture.

36. Understanding Individualistic vs. Collectivistic Values When ELLs are trying to make meaning of mathematics, they are more successful if they operate in a mathematics discourse community. They also need opportunities to work independently. Instructors need to provide students with opportunities to participate both individually and in a group. How do you become aware of the type of value system that is emphasized in the students’ home life? How does that translate to your interactions with students?

37. Observing ELLs’ Cultures in the Mathematics Classroom It is critical for instructors to consider the culture of their students to find out ways in which they have engaged in past mathematics classrooms. Instructors should affirm students’ cultures and ways of doing mathematics. Affirm students in the mathematics classroom by: ValidatingCelebrating ValuingNurturing AcknowledgingShowing Interest

38. Observing ELLs’ Cultures in the Mathematics Classroom What actions do you take to affirm students’ identity? What do you do to build relationships with ELLs in the mathematics classroom?

39. Underwater Dreams Underwater Dreams, written and directed by Mary Mazzio, and narrated by Michael Peña, is an epic story of how the sons of undocumented Mexican immigrants learned how to build an underwater robot from Home Depot parts. And defeat engineering powerhouse MIT in the process. Here is the trailer that is on the web: http://www.underwaterdreamsfilm.com/. http://www.underwaterdreamsfilm.com/

40. Equity and Excellence We want to provide access to ALL students (equity). We also want ALL students to make sense of rigorous, high quality, and cognitively demanding mathematics (excellence). We want them to approach the zone of proximal development, not the zone of minimal effort. We want equity AND excellence. Equity without excellence is meaningless. Excellence without equity is unjust. We must always ask ourselves, what can we do to incorporate both?
