What does an equation have that expression does not
equals sign
What are the two expressions for volume?
(base x height) and (length x width x depth)
Name the dimension for cubic units and the dimension for square units?
Cubic units are 3d and square units are 2d
What does it mean to double and halve? Example: (12 x 13)
Double 13 to get 26 and halve 12 to get 24
What is the order of operations?
Parenthesis, exponent, (multiplication & division), (addition & subtraction)
What does evaluate mean?
solve
Solve this problem: I take the sum of 3 and 5 then divide by 2.
Need parenthesis & solve: (3 + 5) / 2 = 4
What is the difference between a fraction and a whole number?
Something like...A fraction is part of a whole number... a fraction like 1/4 is less than 1, and 1 is a whole number.
Name two place values before and after zero on a number line.
tens, ones, tenths, hundredths
Write an expression using the letter 'Z'
something like... z+2 or 3z or 21-z ... NO EQUALS SIGN
Evaluate and write an equation: If my base of a rectangular prism is 30 and there are 3 layers, what is the volume of the shape?
30 x 3 = 90 cubic units3
What is the ending unit and the name of a shape that has all equal sides and is 2 dimensional?
Square, with square units 2
Write an expression & an equation using the letter 'T'
Something like... 2+t & 3-t=5
What 3d shape has two different sized sides, and list its ending unit.
Rectangular prism & cubic units3
Is this an expression or an equation? What do we solve for first?
9 - 2 + 3 - 4 + 5
expression & solve 9 - 2 first
Solve this equation for B: (((2 + 3) x 4) - 2) = B, what does B equal?
5 x 4 = 20 - 2 = 18 cubic units3
What is a prime number? What is a composite number?
Something like... a prime number is one that cannot be divided by anything but one/ itself. A composite number can be divided by other numbers besides 1 & itself. Like 11 is prime and 6 is composite.
last is minus 1 & it is an equation
What does L x W x H have in common with B x H?
Something like... L x W is the base and both get multiplied by height
What is the difference between a 3d & 2d shape? Explain using equations like B x H & LxWxD...
Something like..a 3d shape does not have layers, height, it only has a base. Or it only has L x W and no D.
What is the commutative property of multiplication & addition?
Something like ... it is the same no matter where they are, like (3 x 2) equals 6 and so does (2 x 3). Same with addition, (4 + 5) = 9 as does (5 + 4).
What is the Distributive property of multiplication & addition?
Something like... a multiplication fact can be broken up into the sum of two other multiplication facts. Break into numbers like factors. Break into smaller parts like (23 x 3) can be broken into (20 x 3) & (3 x 3).
What is the Associative property of multiplication & addition ?
Something like... You can group the factors in different ways, and the product will be the same. Like grouping on (Base) x height, to (length x width) x height. Like (2 + 3) + 4 = 2 + (3 + 4) and same with multiplication. Can be grouped differently but equal the same.
What is the Identity property of multiplication and addition?
Something like ... The product of any number times one is that number. It keeps it's identity when added or multiplied. Like 3 + 0 = 3 same with 21 x 1 = 21
Solve this problem: If Emersyn has 56 stickers, and she has 5 friends. How many stickers does each friend get? Remainder of stickers?
