1. What is an algebraic equation?

a) An equation that has all of its values

b) An equation that contains unknown values
b) An equation that contains unknown values

Ex: 5+__=7 or 5+x=7
2. What is the definition of congruent?

a) A pair or group of shapes that have the same shape and size

b) A pair of shapes that are similar, but not exactly the same

c) A pair of shapes that are completely different from each other
a) A pair or group of shapes that have the same shape and size

The color difference does not matter!!
3. What is a conjecture?

a) An uneducated guess

b) A random idea about math

c) An observation or general conclusion based on a number of facts
c) An obeservation or general conclusion based on a number of facts

Ex: A student observes that 6+0=6, 5+0=5, and 2+0=2. The student's conjecture might be that when you add zero to a number, you get the number you had at the start.
4. What is a coordinate graph?

a) A grid on which you write numbers

b) A 2-dimensional grid which describes the location of an object using the x-axis and the y-axis

c) A piece of graph paper
b) A 2-dimensional grid which describes the location of an object using the x-axis and the y-axis

Think about when you are plotting points on a grid. You were using a coordinate grid, and you may not have known it.
5. What is the dividend?

a) The amount that is divided by another number, or shared equally.

b) The number at the end of a division problem

c) The answer to a division problem
a) The amount that is divided by another number, or shared equally.

Ex: In the equation 15/3=5, the dividend is 15. In other words, the dividend is the number that is being divided.
6. What is the divisor?

a) The answer to a division problem

b) The number that is being divided

c) The number by which another number is divided, or the number of equal groups into which an amount is shared
c) The number by which another number is divided, or the number of equal groups into which an amount is shared

Ex: In the equation 21/3=7, the divisor is 3. In other words, the divisor is the number that is dividing the other number.
7. What is an equation?

a) A multiplication problem

b) A number sentence showing the amount on one side of the equal sign has the same value as the amount on the other side
b) A number sentence showing the amount on one side of the equal sign has the same amount on the other side.

Ex: 5+3=6+2
8. What is expanded notation?

a) A number

b) A set of data

c) Decomposing numbers to show the value of each digit
c) Decomposing numbers to show the value of each digit

Ex: 628 = 600 + 20 + 8
9. What is a factor?
