Imaginative Math and Fractions

Description

The student has already in the first three grades been introduced to the four processes and has achieved skills in addition, subtraction, multiplication and division. Now in the fourth grade we enter into the world of smaller parts to gain facility in applying the four processes to fractions. Fractions are introduced within the context of a story of a king and his lands, who divides them first into quadrants (fourths), and then further divides the lands into pastures and fields, farmland and orchards, and ever smaller fractional parts.

Sample Lesson

The Land of Wylynn

In the second year, the King parceled the land into eighths. The new bridge road divided the southern regions, and the ravine along the steppes in the northwest divided the northern territories.
