How many tens are equal to 6 hundreds?

This number model shows 6 hundreds. How many tens are equal to 6 hundreds?1In this lesson you will learn how to identify equal number of ones, tens, and hundreds by using number models.In this lesson you will learn how to identify equal number of ones, tens, and hundreds by using number models.2Our number system is made of 10 digits.

0, 1, 2, 3, 4, 5, 6, 7, 8, and 9

Each digit has its own place value in a number.Lets ReviewLets review. Our number system includes digits zero through nine. Each digit has its own place value in a number.3

Base Ten BlocksOnesTensHundredsLets ReviewLets review our base ten blocks. Ones are represented by individual cubes. 10 ones make a group of ten. 10 tens make a hundred. (Not sure if I should use the vocabulary cubes, rods, and flats.)4___hundreds101010104= ___tens= ____ones40040100100100100Core LessonLets look at this number model. Each flat represents a hundred. So lets count each one to see how many hundreds are represented here1, 2, 3, 4. There are four hundreds. I wonder how many tens we have. Remember each flat has 10 tens1,2,3,4,5,6,7,8,9,10. Since we know that each flat is a group of 10 tens we can count by tens to find the number of tens10, 20, 30, 40. The number model shows 40 tens. We now know that 4 hundreds is the same as 40 tens. Now lets see how many ones are represented. Each flat represents 100 ones, so we can count by hundreds to find out how many ones we have in 4 hundreds100, 200, 300, 400.5___hundreds7= ___tens= ____ones70070Core LessonLook at this number model. Each flat represents a hundred. So lets count each one to see how many hundreds are represented here1, 2, 3, 4, 5, 6, 7. There are 7 hundreds. I wonder how many tens we have. Since we know that each flat is a group of 10 tens we can count by tens to find the number of tens10, 20, 30, 40, 50, 60, 70. The number model shows 70 tens. We now know that 7 hundreds is the same as 70 tens. Now lets see how many ones are represented. Each flat represents 100 ones, so we can count by hundreds to find out how many ones we have100, 200, 300, 400, 500, 600, 700.6___hundreds =3 ___tens= ____ones30030Core LessonHere we have 30 rods. Remember a rod represents tens. So we have 30 tens. To find the number of hundreds, we can group the rods into groups of ten (rectangles fade in grouping the rods). Ten groups of ten makes a hundred (reveal the 100 under each group). Now we can easily see that we have 1,2, 3 hundreds. Lets count by hundreds to see how many ones we have100, 200, 300. We have three hundred ones. From this number model we can see that 3 hundreds equal 30 tens and 3 hundreds equal 300 ones.
