Vocabulary Cards and Word Walls
The vocabulary cards in this file match the Common Core Georgia Performance Standards. The cards are arranged alphabetically. Each card has three sections.
o Section 1 is only the word. This is to be used as a visual aid in spelling and pronunciation. It is also used when students are writing their own “kid-friendly” definition and drawing their own graphic.
o Section 2 has the word and a graphic. This graphic is available to be used as a model by the teacher.
o Section 3 has the word, a graphic, and a definition. This is to be used for the Word Wall in the classroom. (See ideas for everyday use of a Word Wall below.)
These cards are designed to help all students with math content vocabulary, including ELL, REACH, special education, and regular education students.
Ideas for everyday use of a Word Wall to develop vocabulary knowledge and fluency by the students
Give 3 cloze sentences for student to fill in with words from Word Wall (for example, We walked around the ____________ of the school.)
Have students write own sentences with words from the Word Wall. Have students share three sentences written by their cooperative group on an overhead or document
camera. Have students share examples of hearing, seeing, or using a word from the Word Wall from their
personal lives. Make a game by giving a definition for a word and students race to write the word on the board. Have students make a connection between pairs of words to help memory. Ask students to tell the two
words that they think go together or are connected in some way and to justify their reasoning. Give a clue about a word and then ask students to find the word on the wall that goes with the clue (for
example, This word names a polygon with five sides. … pentagon) Select a Word Wall word and ask students to work with a partner to create a quick web of all the words
they can think of that go with that word. Say a sentence, but leave out a word (from the wall). Have students guess which word belongs in the
sentence. Scramble the letters in a word. Give students a clue to its meaning and see if they can unscramble the
word. Share a topic with the class (e.g., multiplication) and ask students to find all of the words on the wall
that connect to the topic. Make a picture or photo book using the Word Wall words using a scrapbook format, PowerPoint, or
video. Write a story, poem, paragraph or letter including a set number of words from the Word Wall.

deviation
In statistics, the
absolute deviation of
an element of a data
set is the absolute
difference between
that element and a
given point.
The weights of the three
people are 56 Kgs, 78
Kgs, and 88 Kgs.
Step 1: Find the mean. (56+78+88)/3 =
74
Step 2: Determine the deviation of each
variable from the mean.
56 – 74 = -18
78-74=4
90-74=16
Step 3: Make the deviation „absolute”
by squaring and determining the roots.
(eliminate the negative)
(18 + 4 + 16)/3 = 12.67 is the mean
absolute deviation.
The weights of the
three people are 56 Kgs, 78
Kgs, and 88 Kgs.
Step 1: Find the mean.
(56+78+88)/3 = 74
Step 2: Determine the deviation
of each variable from the mean.
56 – 74 = -18
78-74=4
90-74=16
Step 3: Make the deviation
„absolute” by squaring and
determining the roots.
(eliminate the negative)
(18 + 4 + 16)/3 = 12.67 is the
mean absolute deviation.
