Sixth grade does have kids write and graph inequalities, but this one is beyond sixth grade level under Common Core: they don’t really do any operations with negative numbers yet, and definitely don’t solve inequalities with negative coefficients or numbers.

Thanks, as always, Julie. I changed it to 7.EE.4. Does that seem to fit better?

It’s a 6th grade TEK in Texas. Thank you!

Perfect for 7th grade! Can’t wait to do this!

-3x<-2

Can I spice this up for high school students and make it a two-step inequality with fractions?

your we do it all the time
