Estimating is a valuable skill which can be applied frequently in everyday life and can also help simplify problems and check solutions. Estimating uses the skill of rounding to different place values depending on the accuracy of estimation desired.
Let’s look at rounding decimals from a different perspective. We spent some time investigating a different method of rounding.
Rounding decimals is an important skill in estimation and other parts of math. Today’s lesson reviewed how we round decimals using several techniques and reminders. Which one makes the most sense to you?
Our lesson focused on how to order decimals by size, using our skills in place value and decimal comparison.
Today’s lesson focused on how to order and compare decimals, using our skills in place value.
Let’s look at four different ways of representing whole numbers and decimals: standard form, word form, expanded form, and expanded notation. How would these forms help use to understand the concepts?
Here’s the rubric we will use for grading our notebooks.
In today’s lesson we set up our math journals and explored the base ten system. Our guiding question concept: our system has only ten digits (0 to 9), but can represent an infinite amount of numbers. How does that work? Place value is the secret sauce. We compared our system to other number systems which had different concepts of place value.
Welcome to 5th Grade math! We are starting today with a review of some of the vocabulary and concepts we use in discussing our number system.
