October Math Workshop

OCTOBER MATH WORKSHOP

                             

In October, the second grade will be completing unit 2 (measurement) and begin our third unit. Unit 3 is a large unit and has many lessons. This unit will take us to the end of November.  

                       

Unit 3 Place Value, Counting and Comparison of Numbers to 1,000

In this unit the children expand their understanding of units by bundling ones, tens, and hundreds up to a thousand.

Key Vocabulary: 

Standard Form: e.g. 576

 
Expanded Form: e.g. 576 =500 + 70 + 6

Word Form: e.g. Five hundred seventy-six

Unit Form: Stating the amount of hundreds, tens, and ones in each number, e.g., 11 is stated as 1 ten 1 one, 27 as 2 tens 7 ones, 100 as1 hundred, and 576 as 5 hundreds, 7 tens, 6 ones

Base-Ten Numeral: The idea that 1000 equals 10 hundreds, 100 equals 10 tens, and so on

Bundling: Putting smaller units together to make a larger one, e.g. putting 10 tens together to make a hundred

Regrouping: Renaming, (instead of “carrying” or “borrowing,”) e.g., a group of 10 ones is “renamed” a ten when the ones are bundled and moved from the ones to the tens place.

How you can help at home:

-Ask how many ones, tens, and hundreds are in numbers that you and your child come across
-Continue to review addition and subtraction skills.
-Help your child begin to compare numbers by asking questions about “more than”, “less than”, and “equal.”
