Patterns are arrangements of shapes, colors, numbers, letters, words, and etc. for which you can predict which comes next.
Variable - a letter that represents an unknown number.
eg : x, A, n
Expressions - any single number or variable, or combination of operations ( +, -, x, / ) involving numbers. eg : 5, r, 8t, x+9, 2y, -7
Value - a known or calculated amount
Constant - a number that does not change. Increase or decrease that value of an expression.
Numerical Coefficient - a number that multiples the variable
Linear Relation - a pattern made by two sets of numbers that results in points along a straight line on a coordinate grid
eg :
Graph - a visual way to show how two sets of numbers relate to each other
Relationship - a pattern formed by two sets of numbers

Patterns And Expressions
Patterns- Are arrangements of shapes, colours, letters, numbers, etc. For which you can predict what comes next
Constant- A number that does not change. Increases or decreases the value of the expression no matter what the value of the variable
Example: 2x+4, 4 is the constant
Variable- A letter that represents an unknown number
Example: 2x+4, x is the variable
Numerical Coefficient- A number that multiplies the variable
Example: 2x+4, 2 is the numerical coefficient
Expression- Any single number or variable, or a combination of operations involving numbers and variables
Example: 2y-7, 11x, and 14 are expressions
Equation- Mathematical statement with two expressions that have the same value
Example: x+2=3, y-7=(-4)
Value- A known or calculated amount
Linear Relation- A pattern made by two sets of numbers that results in points along a straight line on a coordinate grid
Graph- A visual way to show how two sets of numbers relate to each other
Relationship- A pattern formed by two sets of numbers
Constant- A number that does not change. Increases or decreases the value of the expression no matter what the value of the variable

Patterns and Expressions
For example, in 3y + 2= 14. The 2 is the constant
For example, in 3y + 2= 14. The 3 is the numerical coefficient

Number of the Day
1. Divide the number by two.
2. Expanded Form. (Eg. 1000+200+30+4+0.5+0.06+0.007+1234.567
3.Write the number in words. (Eg. One thousand, two hundred, thirty-four and five hundred sixty-seven thousandths)
4.Round to the nearest hundred. (01234 the hundred stays, 56789 it goes up)
5.What digit is in the tenths place. (For this, it's important to know your place value
6. Double the number. (x2)
7. Find the Circumference. (use the formula: C=2(pi)r)
8. Make a power. ( n*: n is the base, the star is the exponent)
9. Make the power in factored form (the power you did for #8). (Eg. 4x4x4x4x4=1240)
10. Cube the in the ones place. (n*: n is the digit in the ones place, the star is the exponent for cube)
11. Square the in the hundreds place. (n*: n is the digit in the hundreds place, the star is the exponent for squared)
12. Use calculator and round to the nearest hundredth.
13. The product of all the digit. (1x2x3x4x5x6x7=5040. If there is a zero in the number the product is 0)
14. Prime Numbers in the Number of the Day. (Numbers with 2 factors, one and its self)
15. Find the area. (Use the formula: A=(pi)r(squared))
16. Use the divisibility rules.
17. Find the prime factors.
18. Use integer notes.
19. Use subtracting integer notes.
20. Create a fraction.
21. Create an improper fraction.
22. Create a mixed fraction.
23. Convert into a decimal.
24. Create a picture for #21.
25.Convert answer to #21 into a percent.
2. Expanded Form. (Eg. 1000+200+30+4+0.5+0.06+0.007+1234.567
