Students use two rules (one on the length and one on the width) to create square units. Students use rules or another straight edge tool to create square units and determine the area. Students then show their thinking as to how they find the area: counting squares, repeated addition, or multiplication. An extension activity would be for students to create multiply ways to find each area.
There are 6 different rectangles for students to use in order for students to develop the skill of finding area. The first 3 figures have whole number lengths and widths. The last 3 figures have one fractional side and one whole number side.
Also included is a 4 question quiz assessing various skills needed in order to understand area. The first 3 questions have whole number lengths and widths. The last question has one fractional side and one whole number side.
