Mathematics — Grade 4

Language families

In Intrigue of the Past, page 4.7

Students will identify and locate the three language families of contact period North Carolina and calculate the physical area covered by each language family.

Format: lesson plan (grade 4 and 8 Mathematics and Social Studies)

Inside, outside, and all around

Students will distinguish between perimeter, area, and volume. They will use tangrams and graph paper to create two-dimensional figures that will be measured for area and perimeter. By creating layers of centimeter cubes, the students will explore the concept of volume.
