In math, our focus has been on understanding the value of numbers, or place value. Children have been using base ten blocks to build and write numbers in the hundreds and/or thousands, depending on the challenge they need. We have also learned about writing numbers in number words and expanded form. For example, 126 is written as 100+20+6 and one-hundred twenty-six. As you may have heard, many states across the country have adopted the "Common Core Standards" for literacy and math. The emphasis for second graders in math is on addition/subtraction and building a strong sense of numbers through 1000. To meet these new, rigorous standards your child will be working in depth with numbers this year, at an individualized level. To differentiate for various student needs, I meet with math groups of about 4 children each day. Yesterday we began talking about comparing two numbers and the vocabulary "greater than" and "less than.," and "equals." We'll continue this work today and next week.

We have also been using cuisenaire rods to explore numbers and master addition facts. Cuisenaire rods provide a visual and tactile approach to developing number sense and are a favorite math tool in our classroom.

We look forward to having families in at Open House to see our math work and these hands-on math tools! See you Wednesday October 2nd at 6:30!
