Overview Continued
Students will better understand counting to 100 by 1’s, 2’s, 5’s, and 10’s, place value for ones and tens, odd/even numbers to 10, coin combinations to $1.00, and addition/subtraction facts to 20 including doubles. Students will also gain greater understanding of estimation, ordinal numbers (first, second, third), and the concepts of greater than, less than, and equal to. Second graders will use shapes to identify, describe, draw, and compare geometric shapes, explore and describe color, shape, and size of shapes, and use shapes to create and reproduce designs and patterns, explain the answers to math problems, and demonstrate the difference between adding and subtracting.

Students will understand more math vocabulary and practical uses of problem solving words and strategies, more complex geometric concepts and patterns, a variety of measurements, and how to explain their mathematics thinking and processing. Toward the end of the year, second graders will learn to communicate in mathematics, compute in the four basic operations, place value, odd and even numbers, data/predictions/probability, coordinate planes, and perimeter and area.

Enduring Understandings are important ideas that students should carry with them years beyond the instruction received this year.
