![]() So I'll write zero point, if I did that that would be two tenths. Alright, let's do, let's do one more of these. Would be nine hundredths, which is exactly what we have there. So how do I represent that? So zero, that's the ones place. So I have 100 squares here, equal squares, so I've divided it into hundredths, and I've shaded in one, two, three, four, five, six, seven, eight, You see I have 10 columns and each of them has 10 squares in it, so 10 times 10 is 100. Represented by the shaded area? So over here, let's see, I have a hundred squares. So it's going to be three wholes and in the tenths place we would put five. They're equal, so they'reĭivided into tenths, and we've shaded in five of them. We have one, two, three, four, five, six, seven, eight, nine, ten vertical bars. What decimal is representedīy the shaded area? So we have three wholes, and then this whole isĭivided into tenths, now it's divided into these vertical bars. Because the space immediately to the right of the decimal points, Two and seven tenths, we could write 2.7. Write it as mixed number we'd write it as two and seven tenths, but they say what decimal is represented by the shaded area? So instead of writing So this is going to be one, two, and seven tenths. Each of these bars is equal to a tenth and we have seven of them shaded in. Set the number of sections in each model to 1, 10, or 100, and then click in the models to shade sections. And then over here, we've taken a whole and we've divided it into one, two, three, four, five, six, seven, eight, nine, ten equal sections. Model and compare decimals using area models. Represented by the shaded area? So it's going to be This is another whole, so together that's two. And we're done.That each square below represents one whole. And then if you were to do a percent, well, this is 44 per 100, or 44/100, but even here I like lookĪt it as 44 per 100 or 44%. Now, what about as a decimal? Well, 44/100, you could say, well, you have your ones place, and then this is the same thing. We could divide the numeratorĪnd the denominator by four, in which case you would get 11 over 25. Row is 10, 20, 30, 40, and then one, two, three, four. And how many of them are there? Well, let's see, this From estimation, to area models, to grids, one of these is bound to. ![]() Explore different strategies in this unit and find the one that works best for you. When it comes to multiplying decimals, theres more than one way to get the job done. This is a 10 by 10 grid, so there's 100 equal sections here. From estimation, to area models, to grids, one of these is bound to help you master decimals multiplication. So see if you can represent this as the part that's shaded Or another way of thinking about it, 60 per, instead of 100 you could say cent. Multiply the numerator and the denominator by 10, that's the same thing as 60 per 100. Now, what about a percentage? Well, percent means per 100, so one way to thinkĪbout it is six over 10 is the same thing as what per 100? That is equal to, if we And so we have 6/10, so you could just put it right over there. What decimal would it be? Pause the video again and If you divide the numeratorĪnd the denominator by two, that's the same thing as three over five. So the blue represents 6/10 of a whole, or it represents, youĬould just say, 6/10. Nine, 10 equal sections, and six of them are filled in. Into one, two, three, four, five, six, seven, eight, c) For this question, use the part-whole model to fill in the place value grid, decimal box and sentence stems. ![]() Well, let's first thinkĪbout it as a fraction. Part that is shaded in blue as a fraction, as a decimal, and as a percent. What we're going to do in this video is try to represent the Assume that this entire square represents a whole.
