Multiplying decimals 3

The topic  is a topic under the 6th Grade Math Mission. This exercise practices multiplication of decimals. There are numbers with various amounts of decimal places, and which involve multiple lines of work via the standard algorithm.

Types of Problems
There is one type of problem in this exercise:


 * 1) Find the product: This problem simply asks for the product of two decimal numbers. The student is expected to find the correct answer and write it in the available spot.Md3-1.png

Strategies
This exercise is easy to get accuracy badges because the algorithm itself is familiar from earlier topics. The speed badges are hard unless one uses a calculator.
 * 1) You do not need to line up decimal points to multiply decimals.
 * 2) Multiply the numbers as if there were no decimals, then count the decimal places you will need on the final answer. This works because each decimal point is like dividing by a copy of ten.
 * 3) A calculator goes against the spirit of practicing complicated multiplication problems, but can dramatically improve speed.
