Hi! So on the Unit Review and the Test/Retest, there are questions where they give the Area of the circle and the student has to come up with the radius or the diameter which would mean that they would need a good understanding of square roots. And this unit, nor any prior units for 7th grade math, teach the square root concept. I will probably create my own and teach it prior to the Area of a Rectangle--and make the section Square Numbers/Square Roots/Area of Squares. I just thought you should be aware of this. Have a good one!
Deb - thank you for the feedback. We will work on fixing this over the summer while we are reviewing our materials. - Melissa
