Parent Note on Place Value from BAIP

Introduction
This activity sheet will provide you with suggestions on how you can practice the concepts for this standard with your child. There are two types of activities that are available to you on this activity sheet: Activities and Teachable Moments. Activities offer you suggestions on short, structured activities that you can complete with your child. Teachable Moments provide you with quick, easy activities that you can integrate into your daily routine.

Parent Note:
This week in class, we are working on mathematical concepts that are tied with the fourth grade Kansas Mathematics Standard 1, Benchmark 2, Indicator K1, which states: Standard 1 that your child will use numerical and computational concepts and procedures in a variety of situations by Benchmark 2 demonstrating an understanding of whole numbers with a special emphasis on Place value; recognizing, using, and explaining the concepts of properties as they relate to whole numbers; and extending these properties to fractions (including mixed numbers), decimals, and money. The student shows Indicator K1 by identifying, modeling, reading, and writing numbers using numerals, words, and expanded notation from hundredths place through one-hundred thousands place.

Overview for Parents:
This lesson is about demonstrating an understanding of whole numbers with a special emphasis on place value. The numerical system uses periods to identify a group of three digits of a number, separated from other digits by a comma. Within each period, numbers are grouped by tens. Each group of ten determines a Digit's place value. Place value terms are read as the following: hundredths, Tenths, ones, tens, hundreds, thousands, ten-thousands, and one-hundred thousands. A place value chart helps students visualize the value of each digit.

Activities that require children to recognize, use, and explain place value as it relates to whole numbers help them develop an understanding of number sense. To identify, model, read, and write numbers using different forms of whole numbers, children need to understand the place value system. Place value can be defined as the value of a digit depending on where it is placed in a number. For example, in the number 10,956, the digit 1 is in the ten-thousands place. Once a child understands the value of a given digit, the child then has a deeper understanding of what the digit's value is. This allows children to successfully read and write a number in various forms, i.e. numbers (standard), word, and expanded notations. Expanded notation is the method of writing numbers as the sum of powers of ten or as the sum of its units. For example, the number eight hundred seventy-four thousand, two-hundred thirty-nine and thirteen hundredths = 874,239.13 and 874,239.13 = (8 × 100,000) + (7 × 10,000) + (4 × 1,000) + (2 × 100) + (3 × 10) + (9 × 1) + (1 × .1) + (3 × .01) = 800,000 + 70,000 + 4,000 + 200 + 30 + 9 + 0.1 + 0.03.

Concepts:

* Use number sense to identify, model, read, and write numbers in number form using numerals from the hundredths place through one-hundred thousands place.
* Use number sense to identify, model, read, and write numbers in Word form using numerals from hundredths place through one-hundred thousands place.
* Use number sense to identify, model, read, and write numbers in Expanded form using numbers from hundredths place through one-hundred thousands place.
