Bellwork for 9/8 Find the GCF. 1.) 64 and ) 16 and 48 Find the LCM. 3.) 14 and 70 4.) 12 and 54

GCF Greatest common factor = largest number that is a factor of each number – List factors (rainbow) – Bday cake (multiply numbers on left side of cake) *Factors are smaller or equal to original numbers

LCM Least common multiple = smallest number that is a multiple of each number – List multiples (x1, x2, x3, etc.) – Bday cake (multiply numbers on left side AND bottom of cake) *Multiples are larger or equal to original numbers

Rounding 1.Underline the place value you are rounding to 2.Circle the digit to its right – If digit is less than 5, keep the rounding digit the same – If digit is 5 or higher, add one to the rounding digit 3.Drop all digits after the rounding digit

Round to the nearest hundredth

Round to the nearest tenth

Order of Operations

Solve using the order of operations 49 – 80 ÷ x 3

Solve using the order of operations [ (18 ÷ ) ] + 5 3

Divide Decimals DMSCB! 1.Move decimal in divisor to the right until it is at the end of the number 2.Move decimal in dividend the same amount 3.Bring decimal straight up to quotient 4.Divide like normal adding zeros to dividend if necessary

Solve 1458 ÷ 0.3

Solve ÷ 2.7

Multiply Decimals 1.Ignore decimals and multiply normally 2.Count the number of decimal places (digits after the decimal point) in both factors 3.Place the decimal point that many places from the right in the product

Solve 0.98 x 4.6

Add and Subtract Decimals 1.Line up decimal points – Whole numbers have hidden decimal at the end 2.Add or subtract digits in same place value position 3.Add zeros to end of decimal if needed *Order matters when subtracting—first number on top, second number on bottom
