Vocabulary in the Math Claass


Vocabulary in the Math Class

Digit, value, regroup…Oh my!  How do we remember to ask students for the sum, difference, product rather than asking for the answer?

 Using the number:  6 234 753?  What is the value of 6? What digit does the 7 represent?
How can we remember to use this language in our lessons?

Three Tiers of Words


Isabel L. Beck, Margaret G. McKeown and Linda Kucan (2002, 2008) have outlined a useful model for conceptualizing categories of words readers encounter in texts and for understanding the instructional and learning challenges that words in each category present.

Tier One words are the words of everyday speech usually learned in the early grades, albeit not at the same rate by all children. They are not considered a challenge to the average native speaker, though English language learners of any age will have to attend carefully to them. While Tier One words are important, they are not the focus of this discussion.

Tier Two words (what the Standards refer to as general academic words) are far more likely to appear in written texts than in speech. They appear in all sorts of texts: informational texts (words such as relative, vary, formulate, specificity and accumulate), technical texts (calibrate, internalize, periphery), and literary texts (misfortune, dignified, falter, unabashedly). Tier Two words often represent subtle of precise ways to say relatively simple things –saunter, instead of walk, for example. Because Tier Two words are found across many types of texts, they are highly generalized

Tier Three words (what standards refer to as domain-specific words) are specific to a domain or field of study (lava, carburetor, legislature, circumference, aorta) and key to understanding a new concept within a text. Because of their specificity and close ties to content knowledge, Tier Three words are far more common in informational texts than in literature. Recognized as new and “hard” words for most readers (particularly student readers), they are often explicitly defined by the author of the text, repeatedly used and otherwise heavily scaffolded (eg. Made part of a glossary).

Helpful Tips:

Þ   If we think of the Tier Two words as words we see in the curriculum (represent, make statements of comparisons, symbolically represent)
 Þ    If we think of Tier Three words as  academic language related to a field of study (for math: product, quotient, sum, difference)



Tier 3 Words
Words with duplicate meaning in math.

I found this interesting that some math words have duplicate meanings and do our students know the math term?What other terms are there that have more than one meaning?
________________________________________________________________
Word                Common Definition                   Mathematical Definition 
          key                   a tool with which the                  something that gives an 
                                   bolt of a lock is turned                explanation or provides a
                                                                                       solution

                                  four legs                                      information

Tier 2 Words

The following is a list of words that fit into the tier 2 category. The more we can use these words in our classrooms, the more our students will know and in turn use them as well. 

The Twelve Powerful Words and Their Definitions

Word                                         Definition

analyse                            to break apart
compare                                ways they are the same
contrast                                 ways they are different
describe                                 tell about
formulate                              create
evaluate                                 judge
explain                                   tell how
infer                                        read between the lines
predict                                   what will happen next
summarize                           give a short version
support                                  back up with details
trace                                       list in steps


Putting it all together: 
Þ    And we can purposefully plan for math vocabulary in our lessons by using a simple table (see below)
 Þ    Then post these words/anchor charts for kids to reference as they work and for teachers to reference as they deliver a lesson

Citizen Scientists


Citizen Scientists
By Julie Julian, Regional Instructional Coach


The benefits of learning outside is nothing new. We know students are often more engaged and learning is more authentic when we step beyond the walls of our schools. Providing opportunities for students to participate in Citizen Science is a great way to do this across the grades.

WHAT?
Citizen science projects focus on, but are not limited to, nonscientists participating in the processes of scientific research, with the intended goal of advancing and using scientific knowledge.”-National Academies of Sciences, Engineering, and Medicine, “Learning Through Citizen Science: Enhancing Opportunities by Design” 

WHY?
“Current understandings of science learning also suggest that science learning extends well beyond content knowledge in a domain to include understanding of the nature and methods of science.”-National Academies of Sciences, Engineering, and Medicine

HOW?
Collect & record data, analyze, classify, and participate in discussions on various apps and websites:

Dark Night Star Light: The Rothney Astrophysical Observatory is calling on citizen scientists to make brightness observations of the night-time sky over their homes.

Calgary Captured: Help us classify trail camera photos by identifying the animals you see.

Alberta Plantwatch: By reporting when certain plants bloom and leaf out in spring, Albertans contribute vital information for climate change studies. This study of biological timing is called phenology, “the science of appearances”.

NatureLynx: Our users actively contribute to our scientific understanding of Alberta’s ecosystems. Beyond being an exciting, free tool for education, engagement and growth, NatureLynx encourages users to network and mobilize their efforts, both socially and scientifically.

Alberta Community Bat Program: The Neighbourhood Bat Watch website is a place where you can join people from across Canada in reporting your own roost or bat sightings, and participating in the annual bat count.

Call of the Wetlands: a citizen science program that enables the public to monitor amphibians as an important indicator of wetland health.

eBird: Our goal is to gather this information in the form of checklists of birds, archive it, and freely share it to power new data-driven approaches to science, conservation and education.    

eButterfly: A real-time, online checklist and photo storage program, e-Butterfly is providing a new way for the butterfly community to report, organize and access information about butterflies in North America.

WormWatch: monitoring program used to identify ecological changes that may be affecting our environment.

FrogWatch: Worldwide, many wetland species are declining in numbers or have recently become extinct. Monitoring frog and toad populations is one way to check the health of wetland areas.

Citizen Science Portal-Government of Canada: This site included even more citizen science project across the country. Use #ScienceAroundMe to find and share exciting ways to take part in science.
