Tomorrow we will have a small, in-class, graded assignment (basically a pop quiz) on our decimal topics so far.
You should know how to...
*write a decimal in word form and vice versa:
ex: four and twenty-two thousandths = 4.022 OR 12.07 = twelve and seven hundredths
*Shade in a 10ths or 100ths grid to represent or read a decimal:
*estimate with addition, subtraction, multiplication and division
For addition and subtraction, round the numbers to the highest common place value.
ex: 24.67 + 8.04 (the ones place is the highest common place value)
25 + 8 = 33
For multiplication, round EACH number to it's own highest place value.
ex: 213.94 x 7.04
200 x 7 = 1400
For division, round the DIVISOR first and then find a compatible number for the dividend.
ex: 55.827 / 8.09
56 / 8 = 7
*Round decimal values to a given place value.
ex: 14.567 = 14.6 or 254.839 (hundredths) = 254.84
*Compare decimal values.
ex: 12.5 > 12.49 or 0.354 < 0.4
*Put decimal values in order.
Line up the decimals, annex zeros as needed and compare.
You should complete the review worksheet for homework tonight. (correction on number one- Only the 4 should be underlined) Study for the pop quiz tomorrow and don't forget to act surprised when I tell you about it tomorrow. :)
