Place Value

Math Lesson: Comparing Numbers Learning Objective: After comparing numbers, the students will know the difference between a digit and a number. The students will also be able to apply their knowledge in place value, by making new numbers and identifying the place value. The students will analyze and evaluate the place value by writing the number in expanded form rather than standard form. CA Math Standards: AF 1.5 Use expanded notation to represent numbers. NS 1.0 Students understand the place value of whole numbers. NS 1.2 Compare and order whole numbers to 10,000 Anticipatory Set: (15 minutes) Number of the Day (Notebooks)- 10 Write the Number of the Day at the top of the notebook paper. Ask students to tell everything they know about that number. Ask students to think of several models and equations that would represent the Number of the Day. Ask students to represent the Number of the Day in at least four or more different ways. Have students document these in their daily math journals. Choose students to share whose representations will move the class towards further development of number and operational sense. Examples for “10” 6+6=12 12=22-10 3x4= 12 12=10+10-8 10+2+12 2x2x3+12 ½ of 24= 12 24 / 2 = 12 1 ten and two ones Instruction: What is the different between a digit and numbers? Digits are any one of the ten symbols 0,1,2,3,4,5,6,7,8,9 used to write numbers. A number is made up of any combination of these digits.

There is an infinite amount of numbers we can make from these digits. You can think of the highest number you can think of and make it a bigger number by adding 1. Some digits are even, some digits are odd. Even numbers are always multiples of 2 The way we arrange these digits, using place value is how we create numbers. 2 21 279 2,135 Know place values from ones  10,000 Show these place values on a chart (attached) The value of 1,627 1 thousand 6 hundreds 2 tens 7 ones Show standard form: 1,627 Expanded Form 1,000+600+20+7 Word Name: One thousand, six hundred twenty-seven (Write what I say) Guided Practice: The children will receive a sheet protector, marker, and worksheet based on place values. Students will create numbers. Students will show their partner the number. The partner will identify the number in standard form. Then the partner will identify the place value of each digit. The partner will say the word name of the number. Independent Practice: Blue Practice Workbook page Assessment and Closure: For homework tonight, you are going to do 2 worksheets. These worksheets are in your homework cubbies. Go over the practice problems and what they ask. Students will do the Reteach 1.2 and Challenge 1.2 for homework. Reflection:

Were there points in the lesson that were not understood? Do I need to give additional help to the class or certain individuals? Did I begin and end on time, check the classroom environment, and work through the mechanics of the class efficiently? Did I set a pace that was neither too fast nor too slow? What did I do particularly well today? What can I do better tomorrow?
