Areas of Parallelograms, Triangles, and Trapezoids: 5 page visual "doodle notes" set -
When students color or doodle in math class, it activates both hemispheres of the brain at the same time. There are proven benefits of this cross-lateral brain activity:
- new learning
- relaxation (less math anxiety)
- visual connections
- better memory & retention of the content!
Students fill in the sheets, answer the questions, and color, doodle or embellish. Then, they can use it as a study guide later on. Graphic doodle and sketch notes take full advantage of Dual Coding Theory (the way brains process visual and linguistic information) to maximize retention.
- area of a parallelogram (rectangles as well as parallelograms without right angles)
- why it is equivalent to the area of a rectangle with the same length and width
- identifying base and height in different orientations
- altitude of a parallelogram
- using the formula, understanding why it works, labeling units
- composite figures made from parallelograms
- area of a triangle (right triangles and oblique as well)
- why it is equivalent to half of the area of a rectangle with the same base and height
- using the formula for area of triangles and showing why it works
- reminder to use square units for answers
- area of a trapezoid
- why the formula works in terms of "average of the bases"
- showing the concept with equivalent regions of the figure
- practice and examples
Check out the preview for more detail about this item and the research behind it.
Visual note taking strategies like sketch notes or doodle notes are based on dual coding theory. When we can blend the text input with graphic/visual input, the student brain processes the information differently and can more easily convert the new learning into long-term memory.
This strategy also integrates the left and right hemispheres of the brain to increase focus, learning, and retention!
