**Title:** Geometric Shadows

**Description:**
Students will identify objects as translucent, transparent, or opaque. Upon seeing the shadow of the opaque object, students will identify the geometric figure created by the shadow.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
**Standard(s): **

[MA2015] (2) 26:

*halves, thirds, half of, a third of*, etc.; and describe the whole as two halves, three thirds, or four fourths. Recognize that equal shares of identical wholes need not have the same shape. [2-G3]

**Title:** The Horizons of Soil in My Backyard

**Description:**
Students will work in small groups to dig holes 1 meter deep. Students will work with measurements as they dig and measure. Students will observe the different types of soil and how the soil changes as they dig. Students will write and draw in their journals about the soil horizons. The need for soil as an important natural resource will be discussed. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project, funded by the Malone Family Foundation.

**Title:** Using the Number Line to Compare

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students determine differences using the number line to compare lengths. Because this model is based on linear measurement, it is a distinctly different representation from the models presented in the first two lessons of this unit. At the end of this lesson, children are encouraged to predict differences and answer puzzles involving subtraction.
