“Where’s
the math?” This is a question that can be answered by students as they examine
pictures from a virtual math trail. Expanding a student’s awareness of the
world is emphasized throughout this activity. As students share thoughts and
verbally express ideas, they are able to grow and communicate with other mathematically.

Students discover the
relationships between area and perimeter as they prep for playing Square Off, a
wonderful Calculation Nation
®
game. This lesson helps students understand the math of area and perimeter, which
will help to maximize their scores when playing the game. Creating human-sized
rectangles and working with geoboards provide concrete experiences before
moving on to pictorial and abstract work with area and perimeter of rectangles.
