I started my area unit with a short review of simplifying radicals and special right triangles. It’s ALWAYS needed.
The first lesson was about the area of parallelograms and triangles. They learn these formulas in pre-algebra, but I think they needed a little review and I include special right triangles. I also have students highlight the perpendicular parts, so that they can find the base and the height easier. Highlighting helps my struggling kids.
The next day, we talked about the area of rhombuses, kites, and trapezoids. The examples in the flip book include special right triangles and the Pythagorean Theorem.
I also have a foldable that students can use to help organize the area formulas. I made it optional for students to complete this foldable. I also included notes about regular polygons. I just had them take notes in their notebook for those pages. No pictures, sorry. :(
Then, we moved on to circles. The first day, we talked about circumference and arc length. I have a post about how I explain the difference between arc length and arc measure.
The next day, we talked about the area of a circle and the area of a sector. I didn’t do segment area with my kids this year. They struggled with the area of a sector and I didn’t want to create a disaster. I was allowed to leave out a few little topics this year because our math standards were being revised this school year.
The last lesson of the unit was perimeter and area of similar figures. I broke it down as simple as possible. On the flaps of the foldable were the different types of problems. Inside each flap there are two practice problems.
