On Tuesday the students learned how to divide decimals. Divide as you do whole numbers and place the decimal point the quotient directly above the decimal point in the dividend.
If the divisor has one decimal place, then you multiply both the dividend and the divisor by 10, or move the decimal one place to the right. If the divisor has two decimal places, then you multiply the dividend and the divisor by 100 or move the decimal two places to the right.

On Monday, the students learned how to multiply decimals. To multiply decimals, first multiply as you do whole numbers and then place the decimal point in the product. The number of decimal places in the product equals the sum of the number of decimal places in the factors (factors are the numbers you multiply together and product is the answer you get in a multiplication problem).
The students took notes in their spirals and can take the spirals home. While we were going over examples, they would write, “ignore the decimal at the beginning of the problem” and “pay attention to the decimals at the end of the problem.”
