This Google Slides presentation contains a daily problem to focus on each aspect of the CCSS 6th grade math fluency standards NS.1, NS.2, NS.3 and NS.4. This is perfect for interactive whiteboards, or simply working out the problem on your whiteboard with the students. That is my intent for the white space left on each slide.
There are 10 problems for each of these:
Dividing Fractions within Word Problems
Finding the GCF
Finding the LCM
Using the Distributive Property to find Equivalent Expressions
If you prefer a spiral review method of teaching these standards you might like: https://www.teacherspayteachers.com/Product/6th-Grade-Daily-Math-Fluency-Practice-NS1-NS2-NS3-NS4-1808754
