A is for Animal Reports

• We wrote animal reports in writing class.
  It was a Christmas project. We learned about our
  animals habitats, and qualities. We also learned
  about the food they eat and their social skills.
  To find facts about our animals we used websites
  on the computer. We presented our reports to
  second-grade. That is why A is for animal reports.

4
B is for Biographies

• We learned about biographies in social studies.
  It was in unit 1, chapter 2. A biography is a
  book that tells about someone who is important in
  history. We wrote our own biographies about
  someone who was important to history. We
  presented our biographies to second grade and our
  parents. It was called Biography Day. To find
  facts for our biographies, we used the computer
  and a library book. That is why B is for
  biographies.

5
C is for Cursive

• We learned about cursive in handwriting
  class. In cursive all of the letters in a word
  connect. All of third grade has their own cursive
  handwriting book. Jan Z. Olsen was the person
  who created our cursive handwriting books.
  Cursive letters look differently than print
  letters. They are also made differently. That is
  why C is for cursive.

6
D is forDivision

• Division means to separate in to two or
  more equal groups. We learned about division in
  math class. We learned division in units 4, 7,
  and 9. All of the units were called
  multiplication and division. This is how you do
  division first you have to find out the total
  number of items you are sharing. Then you have to
  find out how many groups are sharing. Then you
  have to give each group an equal number of the
  items. Sometimes there are extra. That is called
  the remainder. That is why D is for division

7
E is forEstimate

• This is what estimate means. Estimate
  means when you find an answer that is close to
  the exact answer. Sometimes it may be impossible
  to find the exact answer, so you have to
  estimate. We learned about estimation in math
  class. The operations you can estimate with are
  addition and subtraction. To estimate, you must
  first round to the nearest tens. If the number in
  the ones place is below 5, You must round down.
  If the number in the ones is above 5, You must
  round up. That is why E is for estimate.

8
F is forFractions

• Fractions are a part taken from a whole. It can
  also mean the part that was not taken. We learned
  about fractions in math class. We learned about
  fractions in unit 7. The unit was called
  fractions. In a fraction, there are two numbers.
  The top number is called a numerator. The bottom
  number is called a denominator. This is an
  example of a fraction, (one-fifth). That
  is why F is for Fractions.

9
G is forGeometry

• This is a definition for geometry. Geometry
  means the study of shapes. We learned about
  geometry in math class. It was in unit 6. The
  unit was called geometry. In geometry we learned
  about lines, line segments, and rays. We also
  learned about 3 dimensional shapes, and polygons
  in geometry. That is why G is for geometry.

10
H is forHistory

• History means a story of real events. It also
  means a record of events and their causes. We
  learned about history in social studies. It was
  in unit 2 lesson 3. The lesson was called every
  community has a story. You can learn about
  history by reading a book. One of the histories
  we read about was Mount Dora. That is why H is
  for history.

11
I is for Inference

• An inference is when you use the facts
  the author gives to make a guess. A synonym is
  drawing conclusions. We learned about inferences
  in reading class. It was a skill for every theme.
  To make an inference you must first find all of
  the details. Then you make a guess about
  something the author didnt directly say. That is
  why I is for inference.

12
J is forJefferson

• Jefferson was an American who became the
  president. He was the third president. We learned
  about Jefferson in social studies. I read about
  him for biography day. I wrote my own biography
  about Jefferson. To find facts for my biography I
  used the computer and a library book. An example
  of a book about Jefferson is The History of
  Jefferson. That is why J is for Jefferson.

13
K is forKilo

• Kilo means thousand in the metric system.
  If you said kilogram, you would be saying
  thousand gram. We learned about kilo in math
  class. It was in units 3 and 10. We learned about
  kilo to help learn about measuring. Some examples
  of words that start with kilo are kilogram.
  Kilograms are used for weight. Another example is
  kilometer. Kilo meters are used for measuring
  distance. That is why K is for kilo

14
L is forLattice

• Lattice means one method for solving
  multiplication problems. Another way of
  multiplying is partial products. We learned about
  lattice in math class. It was in unit 9. The unit
  was called multiplication and division. To do
  lattice you need to first draw 2,3,or 4 boxes.
  Then you draw a line through each box so they
  look like this. Then put the number with two
  digits on the top of the boxes, and the number
  with one digit on the side so they look like
  this. Then you multiply the number in the ones
  digit of the number on the top times the number
  on the side. Then multiply the number in the tens
  digit of the number on the top times the number
  on the side. Here is an example
• That is why L is for Lattice.

15
M is forMean

• The mean I am talking about does not mean
  rude or bad. It means the average number in a set
  of data. We learned about the mean in math class.
  It was in unit 10. the unit was called
  measurement and data. This is how you find the
  mean. First you add up all of the data values.
  Then divide by the number of data. That is why M
  is for mean.

16
N is forNumber Grids

• A number grid is a table with rows and
  columns that lists numbers in order. A calendar
  is an example of a number grid. We learned about
  Number grids in math class. It was in unit one.
  The number on the right of a number on the number
  grid is the next number. The number on the left
  is the number before. The number above is 10 less
  and the number below is 10 more. That is why N is
  for number grids.

17
O is forOdd Number

• An odd number is a number that can not be
  exactly divided by 2. We learned about odd
  numbers in math class. It was in unit one. This
  is how to tell if a number is odd or not. If the
  number is divided by two and there is a
  remainder, the number is odd. Some examples of
  odd numbers are 1,3,5,7,9,11,13, and 15. That is
  why O is for odd numbers.

18
P is forParallel

• Parallel means lines that can go on forever
  with out crossing or meeting. We learned about
  parallel lines in math class. It was in unit six.
  The unit was called geometry. Two lines are
  parallel when they can go on forever without
  touching. An X does not have parallel lines
  because the two lines touch. Here is an example
  of parallel lines //. That is why P is for
  parallel.

19
Q is forQuadrangle

• A quadrangle is a polygon with 4 sides 4
  angles. A word that means the same as quadrangle
  is quadrilateral. We learned about quadrangles in
  math class. It was in unit 6. The unit was called
  geometry. A shape is not a quadrangle unless it
  has 4 sides and 4 angles. Some shapes that are
  quadrangles are squares, rectangles,
  trapezoids, and rhombuses. They look like this
• That is why q
  is for quadrangle

20
R is forRegular polygon

• A regular polygon is a polygon whose sides
  are all the same length and angles are all the
  same size. We learned about regular polygons in
  math class. It was in unit 6. The unit was called
  geometry. If a polygons sides and angles are all
  the same size, Than that shape is a regular
  polygon. If all of the sides and angles are not
  the same sizes, than that shape is not a regular
  polygon. Some examples of regular polygons are
  , squares, triangles, and
  hexagons.

That is why R is for regular polygons
21
S is forSquares

• A square is a quadrangle with whose sides are
  all the same length. A square is an example of a
  regular polygon. We learned about squares in math
  class. It was in unit 6. The unit was called
  geometry. If two of the sides on a quadrangle are
  shorter than the other two, than that shape is
  not a square. If all of the sides and angles are
  the same length than that shape is a square. This
  is what a square looks like

That is why S is for square
22
T is forTurn Around Facts

• Turn around facts are numbers that can be
  added or multiplied in any order. We learned
  about turn around facts in math class. It was in
  unit 1 and 2.When you are adding, to do the turn
  around rule you just switch the two numbers that
  you are adding. You do the same thing with
  multiplication. For subtraction you switch your
  answer with the first number you are subtracting.
  Here is an example of the turn around rule
  527, 257. That is why T is for turn around
  rule.

23
U is forU.S customary system

• The U.S customary system is a measurement
  system that is used most commonly in the United
  states. We learned about the U.S customary
  system in math class. It was in unit 10. The unit
  was called measurement and data. The other
  measurement we learned about was the metric
  system. That is used everywhere but the U.S.A.
  Some examples of U.S customary units are inches,
  feet, yards, and miles. That is why U is for U.S
  customary system.

24
V is forVolume

• Volume means the amount of space inside a
  3-dimensional object such as a cube or prism. We
  learned about volume in math class. It was in
  unit 10. The unit was called measurement and
  data. To find the volume you first have to find
  the area of the base. Then you multiply that by
  the height of the object. That is how you find
  the volume. That is why V is for volume.

25
W is forWeight

• Weight means a measurement of how heavy
  something is. We learned about weight in math
  class. It was in unit 3. The unit was called
  measurement. If you were weighing in the U.S
  customary system you would say something is ____
  pounds. If you are weighing in the metric system
  you would say something is ____ pounds. That is
  why W is for weight.

26
X is forXylophone

• An xylophone is a musical instrument that
  is played by hitting small wooden blocks with a
  padded mallet. We learned about xylophones in
  music class. Ms. Mohn taught us about them. To
  play an xylophone you first need two padded
  mallets. Then you gently hit the wooden bars with
  mallet. Each bar makes a different sound. That is
  why X is for xylophone.

27
Y is forYard

• A yard is a unit of measuring length in the
  U.S customary system. We learned about yards in
  math class. It was in unit 3 and 10. Here are
  some equivalencies to a yard. One is that 3 feet
  equals 1 yard. Also 36 inches equals one yard.
  That is why Y is for yards.

28
Z is forZero

• Zero means the number that starts the
  negative and positive numbers. We learned about
  zero in math class. It was in unit 1. On a number
  line the number zero would be before the number
  one and after the number negative 1. That is why
  Z is for zero.

29
In Conclusion

• We wrote our ABC books to review most of
  the things that we learned in third grade. We
  also wrote them to make sure we understand most
  concepts in third grade. I also remembered some
  concepts that I forgot. These ABC books helped us
  get ready for fourth grade.
