Order: Order is involved with many things because it structures the way things are, such as the order of math problems, or order in the government.

Teaching fourth graders about the order of operations in math involves structuring lessons to cater to different learning styles. Girls benefit from social learning and group work, while boys engage better with quick, interactive lessons.

Math: Order of operations

It involves knowledge of addition, subtraction, multiplication, etc. and the knowledge of putting them in order to get the correct answer
Math doesn't really have non-examples as there is only really one way to do a problem. but it would be helpful to continue providing many examples to help students see what it all involves. It can still be confusing for students who are not familiar with math and they can still get confused/caught up on some of the rules
multiplication and division comes first, then comes addition and subtraction
do anything in the parenthesis first
PEMDAS Please Excuse My Dear Aunt Sally
15+5-10= answer: 10
(10+5*2)-2= answer: 18

Under generalize: Students could try to just solve everything in the parenthesis and forget the order because they have to worry about solving things first

A lot of it could just come from being confused and not remembering

Over generalization: not specifically about order of operations, but students can hear the term that "multiplication is just repeated addition."(because it doesn't allow for half numbers and other fractions like that.) which it is in some cases, but would have to just be corrected at a later time when they get into deeper math

(2*2+(4+5))-5= answer: 8

Units I could teach

English: writing
Order of the way words go in a sentence
Government
Government systems
The order of how cities and governments are run
Military branches
Mathematics
Order of operations
Science
Different ranks of animals
Health
different kinds of health and moral codes in later years of health

Students: Fourth Graders

Children should already know how to add and subtract, maybe know how to do basic multiplication and division
They are still growing and need encouragement
Girls would need to work in groups and have the social connections they need to help them learn Lessons for boys should be kept quick and interactive: I could use examples in math problems that would keep them engaged
