Map Scale and the Pioneer Journey
Fourth graders, using a map, ruler and calculator, determine the distance the pioneers traveled from Nauvoo, Ill. to the Salt Lake Valley.
Curated OER
Angles
In this math learning exercise, students measure a series of angles. Then they measure the angles in the triangles and determine the sum of the angles.

Adding and Subtracting Fractions with Like Denominators
Students add or subtract fraction parts of mixed numbers before adding or subtracting the whole number parts. In this fractions lesson, students learn to use a ruler to help them add and subtract fractions with like denominators.
Curated OER
Natural Selection
Students observe, measure and record variations that may be due to genetic inheritance. They look at the length of seeds for germinating pinto and lima beans and measure the distance between eyes in humans. They graph and discuss the...
