Your child was learning about geometry and measurement. We focused on geometric figures called quadrilaterals (four = quad & side = lateral). Terms that we used to further sort shapes were: parallelogram, rectangle, square, and rhombus. We played a geometry “headband” game so that the students could work on these terms by asking specific questions. Of course we included other 2D shapes.
This unit has many vocabulary terms, therefore, math flashcards came home last week to assist.
We have also been talking about area and perimeter. Perimeter = distance around the rectangle. The formula that the students have been using is: side + side + side + side = Perimeter of a rectangle. Area = square units inside the rectangle. The formula that the students have been using is: base x height = Area squared.
