CFU Students, you already know how to identify the place and value for the digits of a decimal number. Now, we will use this skill to add decimal numbers. Make Connection We will add decimals. Learning Objective Activate Prior Knowledge A decimal number includes place values lower than the ones place. Digits to the right of the decimal point represent values less than one. 8 1. 2. 3. 4. 1 2 145 16 2 6 5 “Eight and twelve hundredths” “Fourteen and five tenths” “Sixteen” “Five and twenty-six hundredths” 1. 8.12 2. 14.5 3. 16 4. 5.26 Place Value 45 2 1 3 Decimal Point Ones Tens Hundreds Tenths Hundredths Write the decimal numbers in the Place Value chart below and read them aloud.....

Add decimals Concept Development Addition (  ) means to put together. To add, numbers are lined up by the place value of their digits. A quick way to line up decimal numbers by place value is to line up their decimal points. Composing a number means moving a group of numbers to the next higher place value. Composing is needed when the sum is 10 or more in a place-value column 1. 1 lined up and down (gesture) Vocabulary Tom and his grandfather went fishing. They both caught a fish.
