Triangles
This unit enables scholars to apply the rule for area of a triangle (area equals half base times height). They practice multiplication and division strategies as they calculate areas.

How Close Is Our Estimate?
Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Marvelous Mathematics
Students make a table on the computer, but create fractions and equivalent fractions through the use of color. They are able to manipulate fractions in order to gain a greater understanding of the meaning of whole number that is broken...
Curated OER
Reflections
Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...
Curated OER
Area Adventure
Learners calculate the area of figures using the formula: length x width = area. They solve area problems using paper squares, geoboards, and real-world problems.
Curated OER
Geometry in Art
Students examine mathematical symbols and formulas included in works of art. They analyze quilts for shapes and they each make their own quilt from squares using geometric shapes.
