Place Value of Decimals Select the matching decimal for each number name. 0.650 0.605 600.005 0.065 6.050 Sixty-five thousandths Six hundred five thousandths Matching Students should discuss why sixty-five thousandths is not equal to 0.650 because this is 65 tenths or 650 thousandths and that 0.065 is correct. Students should discuss why 600.005 is not the answer because this is 600 and 5 thousandths and although there is the number 65 in 0.650 is equal to 65 hundredths or 650 thousandths. The correct answer 0.065 has the number 65 and its last digit is in the thousandths. MAFS.5.NBT.1.3a

Rename Decimals Select all the ways that 0.35 can be renamed. Ⓐ 35 tenths Ⓑ 3.5 × 1 10 Ⓒ 350 thousandths Ⓓ 3 and 5 hundredths Ⓔ 35 × 1 10 Ⓕ 35 hundredths B, C, F You can have students discuss why these are the correct answers and what the incorrect answers are equal to. A – 3.5 B – is correct because 0.35 is 1/10 of 3.5 C – is correct because adding a zero in the thousandths place will not change the value D – is equal to 3.05 E – same as A F – is correct because the last digit (5) is in the hundredths place MAFS.5.NBT.1.3a
