Today we’re on to another topic already! Unit 6 focuses on learning the standard algorithm (or shortcut) for multiplication and division. We then use those skills in real-world problems. Our lesson today recaps our objectives, how estimating helps in multiplication, and how the partial algorithm (“box method”) connects to the standard algorithm.

Subtracting decimals
In class today we focused on using estimation while subtracting decimals. We also reviewed the steps to subtract decimals.
Using estimation when adding decimals
Our lesson today focuses on using the skill of estimation when adding decimals. We also looked at various ways to draw different representations of decimals.
Estimating – a math superpower
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.
Rounding decimals
Let’s look at rounding decimals from a different perspective. We spent some time investigating a different method of rounding.
