Building on the base 10 system understanding, here are some other properties of math to know.
Identity Property: watch this video

Associative property: watch this videos

Commutative property: The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.

Closure property:The Closure Property states that when you perform an operation (such as addition, multiplication, etc.) on any two numbers in a set, the result of the computation is another number in the same set .

What are Base 10 blocks?
Working with other Base numbers: Any number 1,2,3,4,5, etc. can form a sequence of numbers, and have rules for place value just like the "Base Ten System," we use today.

Base ten blocks are teaching tools that help students learn about the base ten exchange system, and place value.

Are you having math anxiety? Does learning math cause you to stress out? No worries follow these steps to help ease the stress of the unknown!
First explore the topic
look through the new chapter
skim through the content of the chapter!
Take a few notes of the information
Watch a few video examples
Try out a homework problem
If you get confused about how to solve the homework then re-watch a video. Try out the steps of the math solving process, taking care to pause the video when you need to.
Still stressed? Take 5-10 minutes and watch a fun video about puppies, or do something for 5 minutes that has nothing to do with math. Maybe its cleaning up your dishes from this morning! Came back and try again! see you in 5 or 10 minutes
