*All students will have to know all Math Vocabulary Words and be able to apply each to an example given. Students have vocabulary cards and definitions of each before every lesson. All vocabulary words will be on their Review Tests and Chapter Tests.
Add- Join together sets to find the total or sum. Example: 2 + 5= 7
Addend- Any numbers or quantities being added together. Example: 2 + 3 = 5 2 and 3 are the addends
5 is the sum
fact family- Addition and subtraction sentences that use the same numbers. (6, 7, 13)
Example: 6 + 7 = 13 13 - 6 = 7
7 + 6 = 13 13 - 7 = 6
Greater than- Example 7 > 2 7 is larger than 2 ( Alligator mouth eats the larger number)
Less than- Example 2 < 7 2 is less than 7
Sum- The answer to an addition problem 3 + 4 = 7 7 is the sum
Double- Two addends that are exactly the same 5 + 5 = 10
Near Doubles- Two addends that are next to each other 4 + 5 = 9
Difference- The answer to a subtraction problem. 9 -2 = 7 is the difference
Count back- Start at the largest number and count back the addend you are subtracting and the number you land on is the difference.
Missing addend: The addend that you need to find in an addition or subtraction problem. 8 + ___ = 10 2
10 - ___ = 8 2
7 = 5 + ___ 2
Chapter 9- Vocabulary
Bar Graph: a graph that uses bars to show data
data: Numbers or symbols that show information
Line Plot: A graph used to show how often a number occurs
key: Tells what, or how many, each symbol stands for
picture graph: A graph that has different pictures to show information collected
survey: to collect data by asking the same question
tally marks: marks used in a survey to collect data
symbol: A letter or figure that stands for something
