This is my math journal of what I learned and my amazing Math Teacher Mr. Hilling.

Math Journal 2023

What I'm learning about Expressions and Equations:  Im learning that there are different equations that give you the same answer

What I'm learning about me as a mathematician: im learning that math is hard.

Unit 2 Arithmetic Expressions Including Division of Fractions

What I'm learning about Arithmetic Expressions including Division of Fractions:

Im learning how to divide and multiply fractions and decimals. for example if you convert 9/10 into a decimal it would be .9

What I'm learning about me as a mathematician:

i can use this type of math to help me with stuff like measuring.

What I'm learning about Rational Numbers:  An irrational number cannot be expressed in the form of fractions. Rational numbers are terminating decimals but irrational numbers are non-terminating and non-recurring.

1. Am i starting with + or - ? 2. Am i making it bigger or smaller? 3. Will my answer be + or -?

Rules: 1. Adding a negative is the same as subtracting a positive. 5+1=5-1. 2. Subtracting a negative is the same as adding a positive. 5 - -1= 5=1

What I'm learning about me as a mathematician:Being a mathematician is hard. A lot of stuff you got to know to be a mathematician

What I'm learning about Area, Volume and Surface Area: Im learning that to get the area you have to multiply  length x width x height

What I'm learning about me as a mathematician:  Im getting better at math  as  months and years  goes on

Coordinate plane- is when you take a horizontal line and a vertical number line and intersect them.

coefficient - a number that is multiplied by a variable

Variable - A letter that represents a number

Solution to an equation - a number that can be used in place of varible to make the equation true equivalent expressions - equivalent expressions are always equal to eachother term - a part of an expression dependent variable - the result of a calculation independent variable - is used to calculate the value of another variable

What I'm learning about Statistics and Probability: Numerical data is if you ask a  question that the answer would result in numbers for example "How many  siblings do you have?" is numerical data,   Categorical data  is  when you ask a question like "Whats your favorite  breakfast?" 

What I'm learning about me as a mathematician: i can use what i know  to figure out what i dont

Pawns = X = Varible Cubes ❑ = Constant Legal moves = when you take 1 pawn from each side at the same time. Balance = when the both sides of the scale are the same

Hands on equations (HOE) Helps me understand algebra by letting me know and understand that you have to balance it out and figure out what the value of x is or any other letter.

Ratio - Comparing two numbers Equivalent Ratio - ratios that are the same when we compare them Unit - A type of measurement Tape Diagram - something u can draw to represent a math problem Ratio Table - a model that also represents a math problem

KCF - Keep change flip. when you divide fractions keep the first fraction the same , change ÷ to x , flip the second fraction then multiply. Dividing fractions - Dividing numbers in fraction form. Variable - A number that was assumed (kinda like estimate). Constant - A number that stays the same. Mixed number - whole number and fraction put together. Improper fraction - The top number is larger then the bottom Convert - change. Decimal - a . in a number.

Unit 1~ Ratios and Unit Rates Unit 2~ Arithmetic Expressions Including Division of Fractions Unit 3~ Rational Numbers Unit 4~ Expressions and Equations Unit 5~ Area Volume and Surface Area Unit 6~ Statistics and Probability Glossary

What I'm learning about Ratios and Unit Rates: I'm learning how to compare ratios and unit rates. For example if there are 1 sunflower and 1 rose you would say 1:2 if you say 2:1 it would be automatically wrong because 1 sunflower come before 2 rose

What I'm learning about me as a mathematician: I can use ratios to help me to make something like a recipe. for example, to make purple paint you should have 3 cups of red paint and 2 cups of blue. ratios help you know that that is 3:2
