![]() DOUBLE YOUR EFFORTS: Skip count by 3 tenths or 6 hundredths etc… before you get to decimal multiplication as well. Compose and decompose decimals using part whole models and number lines right away! When you get to the addition/subtraction lessons, you will be miles ahead.Find all of my favorites under the decimal tile on the GAME GRID. Try Hit the Button Number Bonds with decimal numbers, Greg Tang Place Value and expanded form place value. Change some of your own tried and true games to work with decimal numbers. Explore computation mentally before algorithms! ALWAYS PLAY FIRST, because it’s not exploring if we already learned about it.Yes, there are still fact families! Yes, there are still commutative, associative and distributive properties! Compare decimal fraction number properties to whole number properties.Explore which fraction numbers can easily be written as decimals and which cannot and um.Play lots of games writing numbers as “fraction numbers, decimal numbers and word numbers”.Examine decimals on number lines as the infinite quantities between all other whole numbers.Make decimal numbers out of manipulatives, words, money and fractions at the same time.Use actual place value manipulatives and play money in part whole models to compose and decompose numbers.I use a blank number chart and manipulatives while we count – there is a full lesson and more ideas in the Decimal Task Resource. Personally, I do a super quick count by hundreds, tens, and ones and then ask my students, “According to the pattern, what will we count by next?” Even in fourth grade, there is always one who says “tenths” or “decimals”. Introduce decimal numbers with counting circles.Remember that struggle builds strength and it is SOOOO worth it. 47 on 100, or 47 hundredths, 4 tenths, plus seven hundredths.Incorporate these sense making routines into your instruction, wherever you can! But please try to BEGIN with them next time. Plus these one, two, three, four, five, six, seven Which is the same thing as 40 hundredths, shaded in blue. So you see, 47 hundredths, which is all the stuff shaded, that's the same thing as the four tenths. The star right over here, I could write that as seven hundredths. So the star right over here, this is going to, let me actually, let me erase this. So 40 hundredths plus seven hundredths is the same thing as four But what's left over? Well, we still have the So hopefully you're convinced that 40 hundredths is the same So 40 divided by 10 is four, 100 divided by 10 is 10. ![]() ![]() And you'd also divide the numerator by 10, going from hundredths to tenths. The denominator by 10, when you go from hundredths to tenths. Another way you could think about it, when you go from hundredths to tenths, each 10 hundredths, each 10 hundredths, is are equal to one tenth. And so you see, these 40 hundredths that are in blue right over there, that's the same thing as one tenth, two tenths, three tenths, and four tenths. Into a hundred equal sections, but into ten equal sections. Notice, if you look at the orange lines, I've divided my square not So this would be four tenths, (mumbles) doing five tenths, six tenths, six tenths, seven tenths, eight tenths, and nine tenths, and then 10 tenths. If I'm taking the larger, if I'm taking the larger square, instead of dividing it into hundredths, I divide it into tenths. And all I'm doing here, is I'm dividing the larger thing into tents, into tenths, I should say. One is, you could think about dividing this larger, larger square into tenths, so this would be a tenth right over here, that would be a tenth, this would be another tenth, that's two tenths. Now, 40 hundredths is the same thing as four tenths. This is 10, 20, 30, 40 hundredths, plus, one, two, three, four,įive, six, seven hundredths. You see that over here,ġ0, 20, 30, 40 hundredths. ![]() Alright, so let's, let'sĬould say immediately, is we could say that 47 over 100 is equal to 40 hundredths, 40 hundredths. And my question to you is, what is the star going to be equal to? The star is equal to what? And pause the video to I wanna write it as four over 10, plus, plus something over 100. I wanna write it as 40 over, actually lemme write it this way. Now what I'm curious about is, I wanna break up this fraction. ![]() Hundredths of the entire, of the entire whole. Or you could say that this, what's shaded in in blueĪnd green right over here, this represents 47 hundredths. So over here, we have colored in 47 out of 100 equal, smaller squares. So this, this picture right over here, we've taken this square, we've divided it into 100Įqual, smaller squares, and then we've colored in, let's see how many we've colored in. ![]()
