Math is, by definition, a subject about numbers. But at the National Council of Teachers of Mathematics this week, math educators said the subject has its own language, too鈥攁nd knowing how to speak it is critical to success.

In presentations and discussions at the annual conference, held this year here in Chicago, teachers, administrators, and higher education faculty enumerated the ways that math literacy unlocks students鈥 understanding.

Some words have one meaning in general conversation, but another meaning in math. Others, like 鈥渟quare,鈥 can have two different math definitions: the geometric figure, and the square of a number, a type of exponent. Math also has its own grammar鈥攄ecimal points, commas, parentheses, and brackets, for example, all have meanings distinct from those in an English/language arts class.

Internalizing and using this language is one way that students build math knowledge, said Gladis Kersaint, the vice provost for academic affairs at the University of Connecticut, in a presentation on supporting English learners in the subject.

For every lesson, she said, teachers should ask themselves: 鈥淲hat language objective do I have to attend to so that my content objective can be achieved?鈥

Presenting multiple definitions could help students understand new math concepts

Emily Illig, a 4th and 5th grade math teacher in Chicago schools, said she sometimes has trouble defining abstract concepts with her students.

When Illig can鈥檛 demonstrate ideas with physical manipulatives like counters, 鈥渢here becomes this disconnect,鈥 she said in a Q&A session at the conference. 鈥淎nd then I鈥檓 like, well, how do I get them ready for middle school, when things get more abstract?鈥

In a separate presentation, Matthew Winsor, an associate professor of mathematics at Illinois State University, explained one strategy he used to help English learners grasp complex definitions when he taught high school.

Winsor tasked students with creating 鈥渨ord squares鈥濃攊ndex cards divided into four quadrants. In the top left quadrant, students wrote a math term in their own language; in the top right quadrant, they wrote the term in English. Then, they wrote a definition in their own words in the bottom left quadrant鈥攊n whichever language they chose鈥攁nd drew a picture or wrote an example in the bottom right.

69传媒 rely on these tools throughout the course, Winsor said: 鈥淚鈥檝e had a student come back to me the year after and say, 鈥楬ey, Mr. Winsor, I used my word squares today.鈥欌

Other educators used similar strategies with younger students.

In a presentation on supporting struggling elementary schoolers, Laura Drechsel and Carolyn Stadlman, both math educators in the Crystal Lake school district in Illinois, discussed using the Frayer Model, another way to diagram vocabulary words.

In this model, students write the word they鈥檙e defining in the middle of a four-quadrant box. In each of the squares, they write 1) the definition in their own words, 2) facts and characteristics of the concept, 3) examples, and 4) non-examples.

鈥淲hen I first started teaching kindergarten, I thought, 鈥業鈥檓 going to just learn the curriculum, and that鈥檚 going to be OK,鈥欌 said Drechsel, now an interventionist. She soon learned, she said, that she needed tools like this model to help shore up some students鈥 understandings.

English learners will face specific math challenges鈥攂ut also bring unique founts of knowledge

During Kersaint鈥檚 talk on supporting English learners, several teachers identified a hurdle in assessing their newcomer students鈥 math knowledge.

Many recent arrivals have experienced interruptions to their education in their home countries, they said. It can be hard to distinguish when students truly have gaps in their knowledge from when students know the material but don鈥檛 have the math language in English to communicate it.

Math teachers need to be 鈥渓istening hard鈥 to their English learners, Kersaint said. For example, a student might offer a partial definition in English, a Spanish word, and draw a picture鈥攖eachers should consider all of this information as students鈥 demonstration of their knowledge, she said.

English learners may also bring unique skills to math class, said Larisa Bukalov, a math teacher at Bayside High School in New York City.

When these students learn English, they often get explicit instruction in diagramming sentences鈥攁 skill that can help them parse word problems. 鈥淚f you鈥檙e not a native speaker, you鈥檙e a lot more sensitive when you try to translate the [words in the] problem to the algebra,鈥 Bukalov said during Q&A after Kersaint鈥檚 presentation.

For this reason, she said, she often has English learners model how they solved word problems for the group鈥攑ositioning them as classroom leaders.
