Area unit is fast approaching and the best way to teach this unit is hands on! Composite area can sometimes be tricky for students who cannot mental break down the big picture into smaller figures. So, what better way to learn composite area than with tangrams.
Students start with finding the area of each piece of the tangram set. Then as they are making the shape with the tangrams, they can just add up the area of the pieces. Thus they have the composite area.
For this activity, I printed ten sets of tangrams on card stock and five sets of the tangram picture sheets that could be shared between the groups. I laminated the tangram picture sets because students sometimes feel the urge to write on papers. I know the tangram pieces won't stay nice for long but should last for a while.
Hope this helps you with composite area!
Tangrams!
