In TOPIC 1, we will be learning about place value and how to read large numbers. Below you will find helpful information for each math lesson, as well as websites you can visit to practice and reinforce what we are learning in class.
LESSON 11: REPRESENTING NUMBERS
Lesson Objective:
Students will read and write 3digit and 4digit numbers.
Students will read and write 3digit and 4digit numbers.
There are many way to show numbers.
Look at the chart below. This is how you can show the number 1,247 with place value blocks.
A number written in a way that shows only its digits is in STANDARD FORM. So the standard form of the number above is 1,247. Notice we write a comma between the thousands and hundreds place.
A number written as the sum of the values of digits is in EXPANDED FORM. For example, 1,247 in expanded form is 1,000 + 200 + 40 + 7.
A number written in words is in WORD FORM. The word form of 1,247 is: one thousand two hundred forty seven.

Students will name numbers in different ways.
This lesson discusses how numbers can be named in different ways by using different numbers of ones, tens, hundreds, or thousands. For example, 1,200 can be named as one thousand, twohundred or as twelve hundred.
GREATER NUMBERS
Lesson Objective: Students will read and write numbers in the ten and hundred thousands.
This lesson is working with larger numbers.
A PERIOD is a group of digits in a number, starting from the right. Two periods are separated by a comma.
A PERIOD is a group of digits in a number, starting from the right. Two periods are separated by a comma.
The number shown above on the place value chart, can be written in 3 different ways.
STANDARD FORM: 9,876,543
EXPANDED FORM: 9,000,000 + 800,000 + 70,000 + 6,000 + 500 + 40 + 3
WORD FORM: nine million, eight hundred seventy six thousand, five hundred forty three
STANDARD FORM: 9,876,543
EXPANDED FORM: 9,000,000 + 800,000 + 70,000 + 6,000 + 500 + 40 + 3
WORD FORM: nine million, eight hundred seventy six thousand, five hundred forty three
