# 1st Grade Math Worksheets and Class Information

1st grade math initially has four specific areas of focus. These are:

• The attributes of geometric shapes as well as their composition
• Understanding units of length and basic linear measurement
• Understanding the relationships of whole numbers including the grouping of ones and tens
• Develop an understanding of addition, subtraction, as well as sums within 20

The small numbers students have been working with up until the 1st grade are used and expanded upon here by learning strategies for adding and subtracting whole numbers. Length based and discrete objects are used to create models in order to learn to compare, take apart, take from, put together and add to differing situations as well as develop arithmetic operations including addition and subtraction.

Addition and subtraction, counting, and understanding the connections between these concepts is paramount in early 1st grade lesson plans and can build a strong foundation that will be needed later as the concepts and operations become increasingly difficult. It is also important to learn the relationships between the various functions in order to illustrate clearly that there is often many ways to solve the same problem.
