Ten Deep (Decimals)
[Intro: spoken over jazz-funk piano] Pencils up. Every place is worth ten of the place to its right. Ten deep. [Verse 1] Decimal point's the border — wholes on the left, parts on the right, Tenths, hundredths, thousandths — every step a tenth as big, that's tight. Move one place to the left — ten times bigger every time, Move one place to the right — a tenth as much, down the line. Point four-five — say it right — "forty-five hundredths," that's the name, Three point oh-seven — "three and seven hundredths" — "and" is where the point came. A zero at the end changes nothing — point five, point five-oh, same size, A zero in the middle holds a place — point oh-five's ten times smaller — recognize. Every whole number's got a point at the end, hiding out of sight, Eight is eight point oh — drop it in when you line 'em up right. [Hook] Ten deep (ten deep!) — every place is ten times the next, Ones, tenths, hundredths — know the names and pass the test. Line the points up in a column — tenths with tenths, that's the law, Times ten, the point moves right — divide by ten, it moves left, that's all. (Ones!) (Tenths!) (Hundredths!) — ten deep — now you know. [Verse 2: double-time] Comparing? Line the points up, pad the short one out with zeros, then compare, Point six or point five-eight? Point six-oh beats fifty-eight hundredths — check it there. More digits doesn't mean it's bigger — start on the left and go place by place, The first spot where the digits differ — bigger digit wins the race. Rounding? Find your place, then peek one digit to the right, Five or more, round it up — four or less, it stays — that's right. Three point four-seven-six to the hundredths — the six says bump it — three point four-eight, Drop the digits after it — rounding's how you estimate. Adding or subtracting? Stack the points in a straight line, Four point five plus two point three-six — four point five-oh — six point eight-six, fine. Seven minus two point three-five — write seven point oh-oh — borrow down, Four point six-five — the point drops straight to the answer, holding ground. [Hook] Ten deep (ten deep!) — every place is ten times the next, Ones, tenths, hundredths — know the names and pass the test. Line the points up in a column — tenths with tenths, that's the law, Times ten, the point moves right — divide by ten, it moves left, that's all. (Ones!) (Tenths!) (Hundredths!) — ten deep — now you know. [Beat Switch: darker heavier drums, aggressive cadence] Multiplying? Forget the points — multiply like whole numbers, then count, Decimal places in the factors — that's the places in the amount. Point three times point two — three times two is six — two places — point oh-six, Two point five times one point two — twenty-five times twelve, three hundred — two places — three, that's the fix. Dividing by a decimal? Slide the divisor's point until it's whole, Slide the dividend's the same — same number of jumps, that's the goal. Four point eight divided by point six — now it's forty-eight by six — eight, Dividing by a whole? Bring the point straight up — keep the columns straight. Eight point four divided by four — two point one — the point stayed in its lane, Count your places, check your size — a decimal slip's a ten-times pain. [Hook] Ten deep (ten deep!) — every place is ten times the next, Ones, tenths, hundredths — know the names and pass the test. Line the points up in a column — tenths with tenths, that's the law, Times ten, the point moves right — divide by ten, it moves left, that's all. (Ones!) (Tenths!) (Hundredths!) — ten deep — now you know. [Outro: spoken, beat drops to piano] "Three snacks, a dollar twenty-five each. You pay with a five." One point two-five times three — three point seven-five. Five point oh-oh minus three point seven-five — line the points up. One dollar and twenty-five cents back. Every place — ten times the next. Ten deep. Class dismissed.
